Is the Email Encrypted? How to Tell if an Email is Transmitted Using TLS

encrypted email transmission

SMTP TLS encryption is popular because it provides adequate data protection without creating a complicated user experience for email recipients. Sometimes, though, the experience is too seamless, and recipients may wonder if the message was protected at all.

Luckily, there is a way to tell if an email was encrypted using TLS. To see if a message was sent securely, we can look at the raw headers of the email. However, it requires some knowledge and experience to understand the text. It is actually easier to tell if a recipient’s server supports TLS than to tell if a particular message was securely transmitted.

To analyze a message for transmission security, we will look at an example email message sent from Hotmail to LuxSci. We will explain what to look for when decoding the message headers and how to tell if the email was transmitted using TLS encryption.

An Example Email Message

First, we must understand how an email message typically travels through several machines on its way from the sender to the recipient. Roughly speaking:

  1. The sender’s computer talks to the sender’s email or WebMail server to upload the message.
  2. The sender’s email or WebMail server then talks to the recipient’s inbound email server and transmits the message to them.
  3. Finally, the recipient downloads the message from their email server.

It is step 2 that people are most concerned about when trying to understand if their email message is transmitted securely. They usually assume or check that everything is secure and OK at the two ends. Indeed, most users who need to can take steps to ensure that they are using SSL-enabled WebMail or POP/IMAP/SMTP/Exchange services so that steps 1 and 3 are secure. The intermediate step, where the email is transmitted between two different providers, is where messages may be sent insecurely.

To determine if the message was transmitted securely between the sender’s and recipient’s servers (over TLS), we need to extract the “Received” header lines from the received email message. If you look at the source of the email message, the lines at the top start with “Received.” Let’s look at an example message from a Hotmail user below. The email addresses, IPs, and other information are obviously fake.

LuxSci:

The Outlook email was sent to a LuxSci user. The Received headers appear in reverse chronological order, starting with the server that touched the message last. Therefore, in this example, we see the LuxSci servers first.

Received: from abc.luxsci.com ([1.1.1.1])
	by def.luxsci.com (8.14.4/8.13.8) with ESMTP id r7JEfLgH003867
	(version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=NOT)
	for <user-xyz@def.luxsci.com>; Mon, 19 Aug 2019 10:41:21 -0400
Received: from abc.luxsci.com (localhost.localdomain [127.0.0.1])
	by abc.luxsci.com (8.14.4/8.13.8) with ESMTP id r7JEfK0Z030182
	for <user-xyz@def.luxsci.com>; Mon, 19 Aug 2019 09:41:20 -0500
Received: (from mail@localhost)
	by abc.luxsci.com (8.14.4/8.13.8/Submit) id r7JEfKXD030178
	for user-xyz@def.luxsci.com; Mon, 19 Aug 2019 09:41:20 -0500
Received: from dispatch1-us1.ppe-hosted.com (dispatch1-us1.ppe-hosted.com [2.2.2.2])

	(version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=NOT)
	for <someone@luxsci.net>; Mon, 19 Aug 2019 09:41:19 -0500

Proofpoint:

LuxSci uses an email filtering service, Proofpoint. Messages reach Proofpoint’s servers before being delivered to LuxSci. Here’s what their servers report about the email transmission:

Received: from unknown [65.54.190.216] (EHLO bay0-omc4-s14.bay0.hotmail.com)
	by dispatch1-us1.ppe-hosted.com.ppe-hosted.com
        (envelope-from <someone@hotmail.com>);
	Mon, 19 Aug 2019 08:41:18 -0600 (MDT)

Outlook:

And finally, here’s what we see from Oultook’s server.

Received: from BAY403-EAS373 ([65.54.190.199]) by bay0-omc4-s14.bay0.outlook.com
       with Microsoft SMTPSVC(6.0.3790.4675); 
       Mon, 19 Aug 2019 07:41:19 -0700

How to Use Received Message Headers to Tell if the Email is Encrypted

The message headers contain information that can help us determine if an email is encrypted. Here are a few helpful notes to help you decode the text:

  1. We said this above, but the message headers appear in reverse chronological order. The first one listed shows the last server that touched the message; the last one is the first server that touched it (typically the sending server).
  2. Each Received line documents what a server did and when.
  3. There are three sets of servers involved in this example: one machine at Hotmail, one machine at Proofpoint, where our Premium Email Filtering takes place, and some machines at LuxSci, where final acceptance of the message and subsequent delivery happened.

Presumably, the processing of email within each provider is secure. The place to be concerned about is the hand-offs between Hotmail and Proofpoint and between Proofpoint and LuxSci, as these are the big hops across the internet between providers.

In the line where LuxSci accepts the message from Proofpoint, we see:

(version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=NOT)

This section, typical of most email servers running “sendmail” with TLS support, indicates that the message was encrypted during transport with TLS using 256-bit AES encryption. (“Verify=not” means that LuxSci did not ask Proofpoint for a second SSL client certificate to verify itself, as that is not usually needed or required for SMTP TLS to work correctly). Also, “TLSv1/SSLv3” is a tag that means that “Some version of SSL or TLS was used;” it does not mean that it was SSL v3 or TLS v1.0. It could have been TLS v1.2 or TLS v1.3.

So, the hop between Proofpoint and LuxSci was locked down and secure. What about the hop between Hotmail and Proofpoint? The Proofpoint server’s Received line makes no note of security at all! This means that the email message was probably not encrypted during this step.

Hotmail either did not support opportunistic TLS encryption for outbound emails, or Proofpoint did not support receipt of messages over TLS, and thus, TLS could not be used. With additional context, you can know which server supports TLS and which does not.

In this case, we know that Proofpoint supports inbound TLS encryption. In fact, from another example message where LuxSci sent a message to Proofpoint, we see the Received line:

Received: from unknown [44.44.44.44] (EHLO wgh.luxsci.com)
	by dispatch1-us1.ppe-hosted.com.ppe-hosted.com
        (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits))
	with ESMTP id b-022.p01c11m003.ppe-hosted.com
        (envelope-from <from@domain.com>);
	Mon, 02 Feb 2009 19:28:27 -0700 (MST)

The red text makes it clear that the message was indeed encrypted. Based on the additional context, we can deduce that the Hotmail sending server did not securely transmit the email using TLS.

How To Tell if an Email is Encrypted With TLS

  1. When analyzing your message headers, consider the following items to determine if the email is encrypted:
    1. The receiving server will log what kind of encryption, if any, was used in receiving the message in the headers.
    2. Different email servers use different formats and syntax to display the encryption used. Look for keywords like “SSL,” “TLS,” and “Encryption,” which will signify this information.
    3. Not all servers will record the use of encryption. While LuxSci has always logged encryption use, not every email service provider does. It is possible to use TLS encryption and not log it. Sometimes, there is no way to tell from the headers if a message is encrypted if it is not logged.
    4. Messages passed between servers at the same provider do not necessarily need TLS encryption to be secure. For example, LuxSci has back-channel private network connections between many servers so that information can be securely passed between them without SMTP TLS. So, the lack of TLS usage between two servers does not mean the transmission between them was “insecure.” You may also see multiple received lines listing the same server: the server passes the message between different processes within itself. This communication also does not need to be TLS encrypted.
    5. If you are a LuxSci customer, you can view online email delivery reports to see if TLS was used for any particular message. We record the kind of encryption in the delivery reports, so it’s easy to see which emails were encrypted.

How can you Ensure Emails Are Securely Transmitted?

With some servers not recording TLS in message headers, how can you determine if a message was transmitted securely from sender to recipient?

To answer this question accurately, you must understand the properties, servers, and networks involved. It may be easy to determine that the message was transmitted securely if included in the header information. However, the absence of information does not necessarily mean the message was insecurely transmitted. You can only know this if you know what each system’s servers record.

In our example of a message from Hotmail to LuxSci, you need to know that:

  1. Proofpoint and LuxSci will always log the use of TLS in the headers. We can infer that the Hotmail to Proofpoint transmission was not secure as nothing was recorded there.
  2. The transmission of messages within LuxSci’s infrastructure is secure due to private back channel transmissions. So, even though there is no mention of TLS in every Received line after LuxSci accepts the message from Proofpoint (in this example), transferring the messages between servers in LuxSci is as secure as using TLS. Also, the same server can add multiple received lines as it talks to itself. Generally, these hand-offs on the same server will not use TLS, as there is no need. In the LuxSci example, we see this as “abc.luxsci.com” adds several headers.
  3. We don’t know anything about Hotmail’s email servers, so we don’t know how secure the initial transmissions within their network are. However, since we know they did not securely transmit the message to Proofpoint, we are not confident that the transmissions and processing within Hotmail (which may have gone unrecorded) were secure.

Was the email message sent and received using encryption?

We skipped steps 1 and 3 and focused on step 2 – the transmission between servers. Steps 1 and 3 are equally, if not more, necessary. Why? Because eavesdropping on the internet between ISPs is less of a problem than eavesdropping near the sender and recipient (i.e., in their workplace or local wireless hotspot). So, it’s essential to ensure messages are sent securely and received securely. This means:

  • Sending: Use SMTP over SSL or TLS when sending messages from an email client or use WebMail over a secure connection (HTTPS).
  • Receiving: Ensure your POP or IMAP connection is secured via SSL or TLS. If using WebMail to read your email, be sure it is over a secure connection (HTTPS).
  • WebMail: There is generally no record in the email headers to indicate if a message sent using WebMail was transmitted from the end-user to WebMail over a secure connection (SSL/HTTPS).

You can typically control one side and ensure it is secure; you can’t control the other without taking extra steps. So, what can you do to ensure your message is secure even if it might not be transmitted with encryption or if the recipient tries to access it insecurely?

You could use end-to-end email encryption (like PGP or S/MIME, which are included in SecureLine) or a secure web portal that doesn’t require the recipient to install or set up anything to get your secure email message. These methods meet HIPAA and other regulatory compliance requirements for secure data transmission and provide complete confidence that the message will be sent and received securely.

LuxSci’s SecureLine offers flexible encryption options, including TLS, secure web portal, PGP, and S/MIME. Its dynamic capabilities can determine what types of encryption the recipient’s server supports to ensure your emails are always sent securely.

What Is a HIPAA Violation? Types, Examples & How to Avoid Fines

Few terms in healthcare get thrown around as loosely as “HIPAA violation.” It gets invoked when a nurse mentions a patient’s diagnosis to a friend outside of work, when a technician talks about a well-known patient who came through the clinic, or when a physician casually brings up a person’s rare diagnosos at a backyard barbecue — situations that sound like violations but often have nothing to do with the actual law. That confusion isn’t just an oversight, but rather, it points to a gap in understanding what HIPAA covers, who it applies to, and what genuinely puts an organization at risk.

For health care providers, compliance officers and IT professionals, the stakes behind that confusion are anything but casual. The Department of Health and Human Services (HHS) Office for Civil Rights (OCR) has issued settlements ranging from a few thousand dollars to over $16 million for the same underlying failures, such as a missed risk assessment, an unencrypted laptop, a chart accessed by the wrong person. This guide breaks down what actually constitutes a HIPAA violation, the most common ways organizations end up on OCR’s radar, what genuinely falls outside HIPAA’s scope, and what to do if you’re managing risk or responding to an incident right now.

If your organization handles PHI over email — one of the highest-risk channels for exactly this kind of violation — our HIPAA Compliant Email guide is a useful next read once you’ve worked through this one.

What Is a HIPAA Violation?

A HIPAA violation occurs when a covered entity, business associate, or a member of either’s workforce fails to comply with a standard set out in the HIPAA Privacy Rule, Security Rule, or Breach Notification Rule — or fails to follow an internal policy implemented to support HIPAA compliance.

That definition matters because it draws a hard boundary around who can actually commit one. HIPAA applies to:

  • Covered entities — healthcare providers, health plans, healthcare suppliers, payers, and healthcare clearinghouses
  • Business associates — vendors and contractors that create, receive, maintain, or transmit protected health information (PHI) on a covered entity’s behalf
  • Workforce members — employees, volunteers, and contractors of either of the above
image What Is a HIPAA Violation? Types, Examples & How to Avoid Fines

HIPAA does not apply to private individuals acting outside of a covered role — a distinction that trips up far more people than you’d expect, and one we’ll come back to later in this guide.

The Health Insurance Portability and Accountability Act (HIPAA) was designed to protect the confidentiality of medical records and patient data while still allowing healthcare organizations to function and share information when appropriate. A violation happens when that balance breaks down — when PHI is accessed, used, or disclosed in a way the law doesn’t permit, or when required safeguards simply aren’t in place.

The Three HIPAA Rules a Violation Can Break

Every HIPAA violation traces back to one (or more) of three core rules. Understanding which rule is in play helps clarify what actually went wrong — and what needs to be fixed.

RuleWhat It GovernsExample Violation
Privacy RuleWho can access, use, and disclose PHI, and under what circumstancesSharing a patient’s diagnosis with someone outside their care team without authorization
Security RuleAdministrative, physical, and technical safeguards for electronic PHI (ePHI)Failing to encrypt emails in transit or a laptop that stores patient information
Breach Notification RuleRequirements for notifying affected individuals and HHS after a breach of unsecured PHIMissing the 60-day deadline to notify patients after a data breach

Most real-world violations involve more than one rule at once, such as a stolen, unencrypted laptop is a Security Rule failure that can also trigger Breach Notification Rule obligations. Keeping the three rules distinct in your own documentation, though, makes it much easier to identify exactly where a gap exists.

Most Common Types of HIPAA Violations

These are the violation categories that show up most often in OCR settlements, and the ones every provider, payer, and supplier organization should actively guard against.

Unauthorized Access / Snooping

This is the violation most people have actually heard about, usually because of a celebrity or high-profile patient case that made headlines. A staff member accesses a patient’s medical record without a legitimate, job-related reason — often out of curiosity, not malice — and it still counts as a serious violation.

What’s easy to miss here: the violation is about the access itself, not just what happens to the information afterward. Looking at a chart you have no clinical reason to view is a violation the moment it happens, even if you never repeat, share, or act on what you saw. Hospitals take this seriously enough to flag high-profile patient charts automatically and audit access in real time — which is exactly why staff who snoop tend to get caught quickly, and why termination is the near-universal outcome when they do.

A useful way to think about it: the sensitivity of the underlying information isn’t what determines whether accessing it was a violation — the authorization to access it through that specific system is and if a job role requires it. Pulling PHI through a restricted system without a legitimate reason is a violation even in cases where the same information might, in theory, be available through some other, non-restricted channel. Improper access through the wrong door is still improper access.

Example: Dr. Huping Zhou was sentenced to four months in federal prison after accessing celebrity medical records 323 times with no legitimate reason. UCLA Health System was separately fined $865,000 related to similar unauthorized access incidents.

Failure to Conduct a Risk Analysis

The Security Rule requires covered entities and business associates to conduct an organization-wide risk analysis identifying vulnerabilities to the confidentiality, integrity, and availability of ePHI. Skipping this step — or doing a superficial version of it — is one of the single most commonly cited failures in OCR settlements, because it’s foundational: nearly every other safeguard depends on knowing where your actual risks are.

Example: Premera Blue Cross paid $6,850,000, and Excellus Health Plan paid $5,100,000, both tied in part to failures to conduct adequate risk analyses before major breaches occurred.

Insufficient Access Controls

Access controls determine who can view or modify ePHI, and they need to be granular enough that staff can only access the minimum information necessary for their role. When access controls are too loose, such as shared logins, no role-based restrictions, no automatic logoff, organizations lose the ability to actually enforce the “minimum necessary” standard HIPAA requires.

Example: Anthem Inc. paid $16,000,000, the largest HIPAA settlement to date, following a breach connected in part to access control failures affecting nearly 79 million individuals.

Failure to Encrypt ePHI on Portable Devices

Laptops, phones, and USB drives leave the building. When they’re lost or stolen without encryption, an isolated incident becomes a reportable breach — because unencrypted PHI on a missing device is, by definition, unsecured PHI.

Example: Children’s Medical Center of Dallas paid $3.2 million after multiple incidents involving lost, unencrypted mobile devices containing ePHI.

Missing or Incomplete Business Associate Agreements

Any vendor that creates, receives, maintains, or transmits PHI on a covered entity’s behalf — from a billing company to an email provider — is a business associate under HIPAA, and business associates are legally required to sign a Business Associate Agreement (BAA) before handling that data. Skipping this step, or using a vendor without one, is a violation regardless of whether anything actually goes wrong with the data itself.

Example: North Memorial Health Care of Minnesota paid $1.55 million after failing to enter into a BAA with a business associate that later experienced a breach.

Impermissible Disclosures of PHI

This category covers PHI shared with someone who wasn’t authorized to receive it — a press release naming a patient, a social media post, filming patients without consent, or telling family or coworkers more than they’re entitled to know.

Example: New York Presbyterian Hospital paid $2,200,000 after filming patients for a documentary without proper consent.

Improper Disposal of PHI

Paper records tossed in regular trash instead of being shredded, or old hard drives discarded without being wiped, both count as impermissible disclosures — PHI doesn’t stop being protected just because someone’s done using it.

Example: Parkview Health paid $800,000 after leaving patient medical records unattended in a driveway during a records transfer.

Exceeding Breach Notification Deadlines

Once a breach of unsecured PHI is discovered, the Breach Notification Rule sets a hard 60-day deadline to notify affected individuals (and HHS, for breaches involving 500+ records). Missing that window turns a bad situation into a compounding one.

Example: Presence Health paid $475,000 for failing to notify affected individuals within the required timeframe following a breach.

Denying Patient Access to Records

Patients have a right to access their own medical records, generally within 30 days of a request, without excessive fees or unreasonable barriers. Denying or delaying that access is one of the more consistently enforced violation categories in recent years.

Example: Cignet Health of Prince George’s County paid $4,300,000 for denying 41 patients access to their own medical records.

Every one of these categories comes back to the same underlying question: does your organization actually have documented, enforced processes for who can touch PHI, how it’s protected, and what happens when something goes wrong? If email is part of that picture — and for nearly every healthcare organization, it is — our HIPAA Compliance Checklist walks through exactly what needs to be in place.

What Is Not a HIPAA Violation (Common Misconceptions)

HIPAA gets invoked constantly in situations it has nothing to do with — and clearing up that confusion matters, because it helps healthcare professionals, IT and compliance teams focus their actual attention where it belongs.

A family member discussing your health isn’t a HIPAA violation. HIPAA governs covered entities, business associates, and their workforces — not private individuals speaking in a personal capacity. Your mother telling a relative about your diagnosis might be a breach of your trust, but it’s not a HIPAA violation, because she isn’t bound by HIPAA in the first place.

Confusing HIPAA with FERPA or the ADA is common, and usually incorrect. Educational records fall under FERPA (the Family Educational Rights and Privacy Act), not HIPAA — a teacher discussing a student’s grades or attendance isn’t a HIPAA issue. Similarly, questions about a disability accommodation, like a mask exemption or a service animal, generally fall under the Americans with Disabilities Act (ADA), not HIPAA.

Asking about someone’s health isn’t the same as disclosing it. HIPAA restricts what covered entities and their workforces can disclose, it doesn’t restrict what any individual, including a coworker, cashier, or stranger, can ask. Someone asking why you’re wearing a mask or requesting proof of a medical condition might be inappropriate or even illegal under a different law, but it isn’t itself a HIPAA violation.

Vague references aren’t the same as identifiable disclosures. HIPAA violations require that protected health information (PHI) be tied to an identifiable individual. Referring to “a patient” or “a young adult male” in casual conversation is too vague to trigger a violation. Naming a specific person — “my patient, Mike, who lives on Oak Street” — alongside health information crosses that line.

A simple way to keep the distinction clear:

  • A nurse telling friends a specific patient’s name, date of birth, and diagnosis → HIPAA violation.
  • A pharmacist telling a customer their prescription refill is delayed → not a HIPAA violation.

The line isn’t about whether something feels private. It’s about whether protected health information tied to an identifiable person was disclosed by someone bound by HIPAA in the first place.

HIPAA Violation Penalties: The 4-Tier Structure

OCR calculates civil penalties based on the violator’s level of culpability, not just the severity of the incident. Understanding which tier applies matters, because the same underlying mistake can result in wildly different consequences depending on whether it was a one-off oversight or a known, ignored risk.

TierCulpability LevelFine Range (Per Violation)Annual CapExample Scenario
Tier 1No Knowledge$100 – $50,000$25,000The organization could not have reasonably known about the violation
Tier 2Reasonable Cause$1,000 – $50,000$100,000The organization should have known, but the violation wasn’t due to willful neglect
Tier 3Willful Neglect (Corrected)$10,000 – $50,000$250,000Willful neglect occurred, but the issue was corrected within 30 days
Tier 4Willful Neglect (Not Corrected)$50,000 (fixed)$1.5 million+Willful neglect occurred and was not corrected in time

Penalty amounts are periodically adjusted for inflation, and current maximum penalties can exceed $2 million annually per violation category — figures worth confirming against HHS’s current published rates before citing specific numbers internally.

Criminal penalties sit outside this civil tier structure entirely. Knowing or willful violations can result in criminal fines ranging from $50,000 to $250,000, plus up to 10 years in prison for the most serious offenses — typically reserved for cases involving intent to sell, transfer, or use PHI for personal gain or malicious harm.

How Are HIPAA Violations Discovered?

Violations don’t usually surface because someone confesses. They’re found through a handful of consistent channels:

  • Audit logs and automated access-flagging. Most modern EHR systems automatically flag unusual access patterns — a chart accessed by someone outside the care team, or a spike in access to a high-profile patient’s record. This is precisely how most unauthorized-access violations come to light; systems are built to catch exactly this pattern.
  • Patient complaints. Patients can, and do, file complaints directly with HHS when they believe their information was mishandled.
  • Breach self-reporting. Covered entities and business associates are required to self-report breaches meeting certain thresholds.
  • OCR compliance audits. HHS periodically conducts proactive audits of covered entities and business associates, independent of any specific complaint or breach.

One nuance worth understanding: not every violation escalates the same way. A single, isolated mistake, such as an email sent to the wrong recipient or a chart accidentally opened, is often handled through internal correction and documentation. A repeated pattern of the same behavior is a different story entirely, and is far more likely to become something an organization is required to report to HHS. This is one of the most important distinctions for healthcare organizations and compliance teams to build into internal escalation policies: document every incident, but treat repetition as a signal that internal correction alone is no longer sufficient.

How to Report a HIPAA Violation

If you’re a patient, employee, or compliance officer who has identified a potential violation, there are two established paths ti report a violation, and they aren’t mutually exclusive.

Step 1: Report it to the employer or covered entity directly. Most healthcare organizations have an internal compliance officer or reporting process specifically for this purpose. Internal reporting is often the fastest way to get a genuine mistake corrected before it escalates.

Step 2: File a complaint with HHS’s Office for Civil Rights. If internal reporting isn’t appropriate, isn’t effective, or the violation is serious enough to warrant it, complaints can be filed directly through HHS’s official complaint portal. Complaints generally must be filed within 180 days of when the violation was discovered, though extensions are sometimes granted for good cause.

A few practical notes:

  • Anonymous reporting is possible, but limited. OCR accepts anonymous complaints, but the lack of contact information can restrict how thoroughly they’re able to investigate.
  • Retaliation against someone who reports in good faith is itself prohibited under HIPAA.
  • Not every complaint results in a formal investigation — OCR reviews each complaint to determine whether it falls within HIPAA’s scope before proceeding.

How to Avoid HIPAA Violations & Fines

For Organizations

  • Conduct — and document — a genuine risk assessment. This isn’t a one-time checkbox; risk assessments should be revisited whenever systems, vendors, or workflows change.
  • Sign a BAA with every vendor that touches PHI, including email, billing, and IT service providers — no exceptions.
  • Implement role-based access controls so staff can only access the minimum PHI necessary for their specific role.
  • Encrypt ePHI in transit and at rest, especially on portable devices and email, where enforced encryption remains one of the most consistently under-implemented safeguards.
  • Train staff regularly, not just at onboarding. A single training session at hire rarely holds up against years of evolving risk.

For Individual Staff Members

  • Only access patient records tied to a legitimate, job-related reason — never out of curiosity, even for patients you know personally.
  • Never discuss identifiable patient information outside of your care team, including with family, friends, or on social media.
  • Report suspected violations, including your own mistakes, immediately rather than waiting to see if anyone notices.
  • Treat every device and email containing PHI as if it could be lost, stolen, or misdirected tomorrow, because eventually, statistically, one will be.

Since email remains one of the highest-volume channels for exactly this kind of accidental exposure, secure, HIPPA compliant solutions, such as LuxSci’s SecureLine encryption technology, are built specifically to remove the guesswork — enforcing encryption automatically rather than relying on staff to remember to apply it correctly every time.

HIPAA vs. State Privacy Laws

HIPAA sets a federal floor, not a ceiling. States are free to enact privacy laws that are stricter than HIPAA, and when they do, the stricter standard generally governs. This matters for multi-state healthcare organizations especially, such as a provider, payer, or supplier operating across state lines may need to comply with HIPAA everywhere, plus additional, more stringent requirements in specific states.

This guide focuses on federal HIPAA requirements, but compliance officers should treat HIPAA as the baseline, not the finish line, when evaluating their organization’s full regulatory exposure.

What Should I Do Now?

Understanding what counts as a HIPAA violation is the first step. Actually closing the gaps that lead to one is the harder, ongoing work — and email is one of the most common places that work quietly falls through the cracks.

Here are three ways to keep moving forward:

  1. Read our HIPAA Compliant Email guide to understand exactly what makes an email platform compliant — and where standard email tools like Gmail and Microsoft 365 fall short.
  2. Work through our HIPAA Compliance Checklist to audit your organization’s current safeguards against what HIPAA actually requires.
  3. Explore LuxSci’s SecureLine encryption technology to see how enforced encryption and a signed BAA work together to close the exact gaps that show up most often in OCR settlements.
  4. Read our Definitive Guide on the New HIPAA Security Rule, making email encryption mandatory in 2027

Frequently Asked Questions

1. What are the most common HIPAA violations?

The most common violations include unauthorized access to patient records, failure to conduct a risk analysis, insufficient access controls, failure to encrypt ePHI on portable devices, missing Business Associate Agreements, impermissible disclosures of PHI, improper disposal of records, and exceeding breach notification deadlines.

2. What’s the difference between a HIPAA violation and a FERPA or ADA issue?

HIPAA governs protected health information handled by covered entities and business associates in healthcare settings. FERPA governs education records, and the ADA governs disability discrimination and accommodation. A teacher discussing grades falls under FERPA, not HIPAA. A question about a disability accommodation typically falls under the ADA, not HIPAA.

3. How do I report a HIPAA violation?

Report it directly to the employer or covered entity first, if appropriate. If that isn’t effective or the violation is serious, file a complaint with HHS’s Office for Civil Rights within 180 days of discovering the violation, using the official HHS complaint portal.

4. Can I sue someone for violating HIPAA?

No. HIPAA does not provide a private right of action, meaning individuals cannot sue directly under HIPAA. Patients can file a complaint with HHS/OCR, and in some cases may have separate legal remedies under state privacy or negligence laws.

5. Is looking up a patient’s chart without a work reason a HIPAA violation, even if I don’t share the information?

Yes. Accessing a patient’s record without a legitimate, job-related reason is a violation the moment it happens — it doesn’t require sharing, saving, or acting on the information afterward. This is one of the most consistently enforced categories, particularly for high-profile or celebrity patients whose charts are routinely audited.

LuxSci Email Security

What Is Secure Email? The Complete Guide for Healthcare Organizations

In healthcare IT, the term “secure email” gets thrown around loosely. Vendors slap the label on anything with a padlock icon, and internal teams often assume that because their provider offers TLS, they’re covered. They’re not, and the gap between what’s assumed and what’s actually required is where data breaches occur and HIPAA violations happen.

This guide breaks down exactly what secure email means from a technical and regulatory standpoint, why the email platform your staff uses every day probably isn’t compliant out of the box, and what to look for when evaluating a provider that needs to protect PHI at scale. If you want the full picture of what compliance requires beyond email specifically, our HIPAA Compliance Checklist is a useful companion read.

What Is Secure Email?

Secure email refers to an email system that protects the confidentiality, integrity, and availability of message content — specifically PHI — through a combination of technical safeguards and contractual protections. It’s not a single feature. It’s a stack of controls working together.

At minimum, secure email in a healthcare context includes:

  • Enforced encryption in transit, so messages can’t fall back to plaintext delivery
  • Encryption at rest, so stored messages remain protected on the server
  • Authentication protocols (SPF, DKIM, DMARC) that prevent spoofing and impersonation
  • Access controls and audit logs that track who accessed what, and when
  • A signed Business Associate Agreement (BAA) with the email provider

The distinction that trips up most organizations is this: encryption is a component of secure email, not the whole picture. A provider can offer encryption and still fail to meet HIPAA requirements if that encryption isn’t enforced, if there’s no BAA in place, or if audit logging doesn’t exist. Secure email is the combination of all these pieces functioning as a system, which is why it needs to be evaluated holistically rather than checked off feature by feature.

For healthcare provider, payer, and supplier organizations, this matters because email remains one of the highest-volume channels for PHI exposure, from clinical referrals to patient billing statements to routine staff communication. Getting the definition right is the first step toward closing the compliance gap.

Why Standard Email Is Not HIPAA-Compliant

Many healthcare organizations run on Gmail (Google Workspace) or Microsoft 365, and most assume they’re protected because encryption exists somewhere in the stack. That assumption is the single most common — and most dangerous — misconception in healthcare email security.

Here’s the problem: standard email services use opportunistic TLS by default. TLS is attempted between mail servers, but if the receiving server doesn’t support it, the message is delivered anyway — unencrypted, in plaintext. Neither the sender nor the recipient typically sees a warning. The email just goes through.

This isn’t a hypothetical edge case. IT professionals managing healthcare email infrastructure have flagged this exact issue directly: opportunistic TLS is often enabled by default and creates a false sense of security, since it offers no guarantee that a given message, including one containing PHI, won’t be transmitted in plaintext if the recipient’s mail server doesn’t support encryption. Organizations assume they’re protected simply because TLS is technically “on,” without realizing it isn’t enforced.

That gap has real consequences under HIPAA. The Security Rule currently treats transmission encryption as an “addressable” safeguard, meaning covered entities can, in theory, implement an equivalent alternative measure instead. In practice, regulators and auditors from the Office for Civil Rights (OCR) expect enforced encryption as the standard of care. “Addressable” has never meant optional — it means an organization needs a documented, defensible reason if it isn’t doing enforced encryption, and few reasons hold up under scrutiny. Finally, under OCR’s proposed changes to the HIPAA Security Rule for ePHI, scheduled for final publication in July 2027, email encryption moves from addressable to mandatory.

Beyond the encryption gap, standard consumer and even most business email plans typically lack:

  • A BAA that’s actually offered and signed (available on some enterprise tiers, but not automatic)
  • Enforced access controls beyond basic password authentication
  • Audit logging sufficient to meet HIPAA Security Rule requirements
  • Built-in encryption at rest guarantees for stored messages

None of this means Gmail or Microsoft 365 are inherently insecure products. It means their default configuration is built for general business use, not for an environment where every misrouted or intercepted message carries breach notification liability. Making either platform HIPAA-appropriate requires layering on additional tools, policies, and critically, a provider relationship that includes a signed BAA covering the exact services in use. 

The Technical Components of Secure Email

Secure email is built upon five technical layers. Understanding each one, and where it fails in standard email, clarifies exactly what a compliant solution needs to deliver.

Encryption in Transit (TLS)

Transport Layer Security (TLS) encrypts the connection between mail servers as a message travels from sender to recipient. There are two flavors, and the difference between them is the crux of most healthcare email compliance failures:

  • Opportunistic TLS attempts an encrypted connection but falls back to unencrypted delivery if the receiving server doesn’t support it. This is the default across most consumer and business email platforms.
  • Enforced TLS requires an encrypted connection for delivery to succeed. If encryption can’t be established, the message fails to send rather than going out in plaintext, or a link to secure portal can be sent to securely access the information.

HIPAA’s Security Rule lists encryption as addressable, but enforced TLS has become the de facto standard that auditors and OCR expect from covered entities and business associates handling PHI over email. As one healthcare IT professional put it while debating this exact tradeoff internally: the goal is to require TLS for all outbound email and then document the remaining controls around it, treating enforced TLS as the technical baseline, with policy and process built on top.

Encryption at Rest

Transit encryption only protects a message while it’s moving. Once it lands on a mail server — sender’s outbox, recipient’s inbox, backups, archives — it needs to remain encrypted in storage. This is encryption at rest, and it’s where many organizations underestimate their exposure.

Encryption in transit alone offers zero control over a message after it’s been delivered. If the destination server isn’t itself encrypting stored data, or if a backup snapshot is taken without encryption, PHI sitting in an inbox is exposed regardless of how securely it arrived. HIPAA’s Security Rule requires safeguards for ePHI both in transit and at rest, a compliant secure email provider needs to guarantee both, not just one.

End-to-End Encryption (S/MIME, PGP)

End-to-end encryption (E2EE) encrypts message content itself, not just the connection it travels over — meaning even the email provider can’t read the content. Two standards dominate here:

  • S/MIME uses certificate-based encryption and is common in enterprise environments, such as healthcare, particularly where organizations already manage a public key infrastructure.
  • PGP (Pretty Good Privacy) uses a public/private key model and is more common in technical or security-conscious communities, though it’s less frequently deployed at scale in healthcare due to key management complexity.

E2EE isn’t a baseline requirement for every PHI-containing email, enforced TLS plus encryption at rest satisfies most use cases. But it becomes necessary for especially sensitive communications, cross-organization data sharing where you don’t control the recipient’s infrastructure, or when a business associate agreement specifically requires it.

Authentication (SPF, DKIM, DMARC)

These three protocols work together to prevent domain spoofing and email impersonation, a growing attack vector against healthcare organizations specifically, given how often phishing campaigns impersonate providers, payers, or patients.

  • SPF (Sender Policy Framework) specifies which mail servers are authorized to send email on behalf of a domain.
  • DKIM (DomainKeys Identified Mail) adds a cryptographic signature verifying a message wasn’t altered in transit.
  • DMARC (Domain-based Message Authentication, Reporting & Conformance) tells receiving servers what to do when SPF or DKIM checks fail, and provides reporting visibility.

Without these configured correctly, an organization’s domain can be spoofed to send convincing phishing emails to patients or staff, creating a security failure that compounds the compliance risk of email interception.

Digital Signatures

Digital signatures verify sender identity and confirm a message hasn’t been tampered with between sending and receipt. Paired with encryption, they close the loop on message integrity, confirming not just that content was protected, but that it came from who it claims to have come from and arrived unaltered.

What Makes Email HIPAA-Compliant Specifically

Technical safeguards alone don’t make email HIPAA-compliant. Compliance is a combination of technology, contracts, and documented processes — all four need to be in place simultaneously. This includes:

A signed BAA with your email provider – Any vendor that transmits, processes, or stores PHI on your behalf is a business associate under HIPAA, and business associates are legally required to sign a BAA before handling that data. Email providers have persistent access to ePHI — even end-to-end encrypted messages pass through their infrastructure at some point — which makes this requirement absolute, not situational. If a provider won’t sign a BAA, using them to send or store PHI isn’t a compliance risk you can mitigate; it’s a violation from the start.

Encryption as an addressable safeguard – Under 45 CFR §164.312(e)(2)(ii), the HIPAA Security Rule lists encryption of ePHI in transit as “addressable” rather than strictly “required.” In practice, this doesn’t mean optional, it means an organization must implement it, or document and justify an equivalent alternative safeguard. Enforced encryption has become the expected standard, and with the newly proposed HIPAA Security Rule planned for July 2027 publication, NPRM would formalize that expectation by making encryption of ePHI in transit and at rest mandatory rather than addressable. Organizations still relying on opportunistic TLS as their “equivalent alternative” should treat this as a closing window.

Access controls and audit logs – HIPAA requires the ability to track who accessed PHI, when, and what they did with it. This means role-based access permissions, multi-factor authentication, and a complete, retained audit trail — not just for compliance reporting, but for identifying and responding to incidents quickly.

The encryption safe harbor – This is one of the most consequential, and most underused, provisions in HIPAA. If PHI is sent via properly encrypted email and ends up misdirected to the wrong recipient, it is not a reportable breach under the Breach Notification Rule, because the encrypted content is considered unreadable and therefore not “unsecured PHI.” The exact same misdirection with unencrypted email is a reportable breach, triggering notification obligations to the individual and to HHS/OCR. Encryption isn’t just a security best practice here, it’s the line between a non-event and a formal breach investigation.

HITRUST certification as a trust signal – When evaluating vendors, HITRUST CSF certification is a strong external indicator that a provider’s security controls have been independently assessed against a recognized healthcare-specific framework. It’s not a HIPAA requirement in itself, but it meaningfully reduces the diligence burden on your side when vetting a provider.

Types of Healthcare Email That Must Be Secure

Not all internal debate here is about “should we secure email” — it’s about scope. Which specific email flows actually carry PHI, and therefore need to run through a compliant channel? In practice, the answer is broader than most teams initially assume.

Screenshot 2026 07 29 at 9.47.13 AM What Is Secure Email? The Complete Guide for Healthcare Organizations

The common thread: if a message references anything that could identify a patient in connection with health information — a name next to a diagnosis, an account number tied to a service date, an annual test reminder — it needs to move through a secure channel, regardless of whether it’s clinical, financial, or administrative in nature.

How to Evaluate a Secure Email Provider for Healthcare

Vendor evaluation in this category tends to go one of two ways: teams either take a provider’s “HIPAA-compliant” label at face value, or they get buried in RFP questions without knowing which answers actually matter. Ask these key questiosn to focus the evaluation on what’s operationally and legally significant.

“Does the provider sign a BAA? This is the first filter, not the last. If a vendor won’t sign a BAA — or offers a heavily limited one — everything else is irrelevant. Some organizations go a step further and negotiate indemnity or make-whole clauses into the BAA itself, seeking financial protection beyond the baseline liability allocation.

What encryption methods are supported? Confirm specifically whether the provider offers TLS only, or also supports S/MIME and/or PGP for end-to-end encryption where needed. TLS-only coverage is sufficient for most standard PHI communication; organizations with cross-border data sharing or especially sensitive use cases may need E2EE options available.

Is encryption enforced or opportunistic? This is the single most important technical question to ask directly, in those terms. A vendor that describes its encryption vaguely, without distinguishing enforced from opportunistic delivery, hasn’t answered the question. Push for specifics.

How are large attachments handled? Lab results, imaging files, and clinical documents often exceed standard attachment size limits. Confirm the provider has a secure, compliant method for large file transfer that doesn’t force users onto an unencrypted workaround.

What audit logging and reporting capabilities exist? You need visibility into delivery, access, and any failed encryption attempts, not just a generic sent/received log. Ask whether logs are retained for a period consistent with your organization’s HIPAA documentation requirements.

Do they support high-volume transactional email? Appointment reminders, billing notices, and patient communications at scale require infrastructure built for volume without sacrificing per-message compliance. Confirm the provider’s platform is built for this your specific pattern, not just person-to-person messaging.

Is the platform US-based with US data residency? For many healthcare organizations, where data physically resides — and under which jurisdiction — is a material factor in vendor risk assessment, particularly for payers and larger provider organizations with strict data governance policies.”

One operational factor worth weighing alongside these questions: secure email portals — the kind that require recipients to click through to a separate web page to read a message — solve the encryption problem but often create a real adoption problem. IT teams have reported a direct conflict between phishing-awareness training and portal-based workflows: staff and patients trained not to click suspicious links in emails are, understandably, reluctant to click the “secure link” a portal email contains. This is a legitimate reason many organizations increasingly prefer platforms that enforce encryption transparently in the background — like LuxSci’s SecureLine encryption technology — rather than routing every message through a separate portal experience.

Secure Email Checklist for Healthcare Organizations

Every safeguard covered in this guide comes down to a handful of concrete, verifiable actions. Use the checklist below as a working reference for what needs to be in place across your legal agreements, technical controls, and internal processes. This is not a one-time setup task, but something worth revisiting as your email volume, vendors, and regulations evolve. Share it across  your compliance and IT teams as a starting point for an internal audit.

  • Legal and Contractual – BAA signed with email provider and all third-party vendors handling PHI.
  • Encryption – Forced TLS, not opportunistic only for emails in transit and all stored data encrypted with AES-256 bit encryption.
  • Access and Audit – Unique user IDs, role-based access, and login monitoring with advanced MFA enabled for all email accounts; audit logs active and maintained.
  • People and Processes – Staff trained in PHI handling, established breach response plan, annual email security policy review.

What Should I Do Now?

Secure email isn’t a single setting you switch on — it’s a combination of enforced encryption, a signed BAA, access controls, and documented process working together. Get any one piece wrong, and the rest doesn’t hold up under an OCR audit or a breach investigation.

If your organization is still relying on opportunistic TLS, an unsigned or incomplete BAA, or a patchwork of workarounds to move PHI through email, now is the time to close that gap, especially with the proposed 2025 HIPAA Security Rule update poised to make encryption a mandatory requirement rather than an addressable one in 2027.

Below are three ways you can continue your journey to securing your healthcare email:

  1. Explore LuxSci’s SecureLine encryption technology to see how automated encryption, enforced TLS, and a signed BAA work together — no complex configuration required.
  2. Read our HIPAA Compliance Checklist to understand the full scope of what your organization needs to have in place beyond email.
  3. Stay ahead of the new regulation with Email Encryption Under the New HIPAA Security Rule for a closer look at what the mandatory encryption shift means for your organization.

FAQs

1. Is email HIPAA compliant?

Email can be HIPAA compliant, but only when the right safeguards are in place — enforced encryption, a signed BAA with your email provider, access controls, audit logs, and staff training on PHI handling. Standard email without these safeguards is not compliant.

2. Do I need to sign a BAA with my email provider?

Yes. Email providers have persistent access to ePHI — even encrypted messages pass through their servers — making them Business Associates under HIPAA. A signed BAA is required. If your provider won’t sign one, you cannot legally use them to send or store PHI.

3. What is the difference between opportunistic TLS and enforced TLS — and which does HIPAA require?

Opportunistic TLS attempts encryption but falls back to plaintext if the recipient’s server doesn’t support it. Enforced TLS stops delivery rather than sending unencrypted. HIPAA’s Security Rule treats transmission encryption as an addressable specification, in practice, enforced TLS is the standard auditors and OCR expect. The proposed 2025 HIPAA Security Rule NPRM would make encryption of ePHI in transit a mandatory requirement in 2027.

4. What happens if I send PHI in an unencrypted email?

It is an impermissible disclosure under HIPAA’s Privacy Rule and triggers the Breach Notification Rule, requiring you to notify the individual and HHS/OCR within 60 days. Penalties range from $100 to $50,000 per violation. Had the email been properly encrypted, the same incident would qualify for HIPAA’s encryption safe harbor, meaning no notification required.

5. Is Gmail or Microsoft 365 HIPAA compliant for sending patient emails?

Neither is compliant in their default configuration. Both use opportunistic TLS, meaning PHI can be sent in plaintext if the recipient’s server doesn’t support encryption. A signed BAA is available on enterprise plans but doesn’t close the technical gap alone. A purpose-built HIPAA-compliant email platform is the reliable solution.

New HIPAA Security Rule Update: Mandatory Email Encryption Delayed to 2027

If you’ve been waiting for the final word on the new HIPAA Security Rule before you touch your email encryption strategy, you now have an official reason to keep waiting.

Our advice: Don’t do it.

What is the new HIPAA Security Rule for ePHI?

The Department of Health and Human Services’ Office for Civil Rights had targeted May 2026 for a final rule implementing the most significant update to the HIPAA Security Rule in over two decades. The proposal eliminates the “addressable” standard and makes encryption of ePHI in transit and at rest mandatory for every covered entity and business associate. That deadline came and went quietly. Now we know why: an updated federal regulatory agenda shows OCR’s timeline has moved to July 2027, with the rule-making downgraded from “final rule stage” to “long-term action.” OCR is still working through more than 4,700 public comments on the January 2025 proposal.

For an industry that had been expecting a tighter deadline, a year-plus delay is the kind of news that invites a collective exhale — and a shelved project plan. At LuxSci, we think that would be a mistake, for three reasons:

  • The current rule already requires you to address encryption. “Addressable” was never “optional.” It has always meant you must implement the safeguard, implement an equivalent alternative, or document in writing why neither is reasonable for your organization. Most healthcare organizations have never done that documentation rigorously, and OCR’s existing enforcement authority applies today, not in 2027.
  • Breach costs haven’t waited for the rule. IBM’s 2025 Cost of a Data Breach Report puts the average healthcare breach at $7.42 million, still the highest of any industry. At the same time, email remains the number one attack vector into healthcare organizations. None of that risk is paused by a regulatory delay.
  • Delay is not withdrawal. OCR has not signaled it’s abandoning the encryption mandate, only that it’s taking longer to finalize it. Organizations that build now toward the standard already proposed will be ahead (and more secure) regardless of exactly when, or in what final form, the rule lands. Organizations that wait risk a compressed scramble once it does.

What should healthcare IT and compliance leaders actually do with this news?

Reevaluate your ePHI security posture, recalibrate its urgency, and use the extra runway to do the job right, instead of racing against a deadline. This includes:

  • Getting a real inventory of where ePHI moves by email today, inbound and outbound, and where encryption is inconsistent or absent.
  • Closing the documentation gap on “addressable” now, while you have time to do it well rather than defensively.
  • Pushing your email vendor for concrete answers on encryption standards, MFA enforcement, audit logging, and breach notification — the same technical controls the proposed rule would make mandatory.
  • Building (or updating) a written, enforcement-ready posture: policies, vendor agreements, certifications and verifications, test results, and training records that would hold up under an OCR investigation today, not just in a future compliance deadline.

Can a Website Be HIPAA Compliant?

A website can be HIPAA compliant when it incorporates security measures, privacy protections, and data handling practices that meet HIPAA regulatory requirements. Healthcare organizations must implement encryption, access controls, audit logging, and secure data storage for websites that collect, store, or transmit protected health information. A well configured HIPAA compliant website helps healthcare providers maintain patient privacy while offering online services.

HIPAA Website Requirements

Websites handling protected health information must meet the standards established in the HIPAA Security Rule. These requirements include encryption for data transmission using protocols like TLS 1.2 or higher. Access controls limit website data viewing to authorized personnel with appropriate login credentials. Audit logging tracks all user activities and data access attempts across the website. Session timeouts automatically log out inactive users to prevent unauthorized access. Regular security testing identifies and addresses potential vulnerabilities. These measures work together to protect patient information from unauthorized access or disclosure.

Website Hosting and Infrastructure

HIPAA compliant hosting provides the foundation for a secure healthcare website. When selecting a hosting provider, healthcare organizations look for companies willing to sign a Business Associate Agreement (BAA). This legal document establishes the hosting provider’s responsibilities for protecting health information. The physical location of servers matters, with many HIPAA compliant services using data centers with restricted access, environmental controls, and monitoring systems. Network protection typically includes firewalls, intrusion detection, and regular security updates. Organizations often choose dedicated hosting environments rather than shared servers to maintain data separation.

Patient Data Collection and Forms

Most healthcare websites collect information through online forms. HIPAA compliant websites include appropriate authorization language on these forms before gathering protected health information. Well-designed websites explain how patient data will be used in clear, accessible language. Form data requires protection both during transmission and after submission. Many websites use secure database connections and encryption for stored information. Healthcare organizations determine what information they actually need to collect, following the minimum necessary standard from HIPAA regulations. User-friendly form design can improve completion rates while maintaining compliance.

Secure Patient Portals and Interaction

Patient portals on HIPAA compliant websites allow secure access to medical records, appointment scheduling, and provider communications. These portals employ authentication measures like password requirements and account recovery processes. Many implement automatic timeout features that log out inactive users after a set period. Secure messaging features enable patient-provider communication without using standard email. The best patient portals maintain detailed logs of all system access and actions. Healthcare organizations integrate these portals with their electronic health record systems for data consistency and accuracy.

Mobile Responsiveness and App Integration

Modern HIPAA compliant websites function across various devices while maintaining security protections. Mobile responsive design allows patients to access information securely from smartphones and tablets. When healthcare organizations develop companion mobile apps, these applications need the same HIPAA compliance measures as their websites. Integration between websites and mobile applications requires secure API connections and consistent authentication methods. Many healthcare providers test their digital platforms across multiple devices to ensure both functionality and security. The mobile experience influences patient satisfaction with digital healthcare services.

Compliance Maintenance

Healthcare websites require regular updates and monitoring to maintain HIPAA compliance over time. Technology changes quickly, and security measures that worked previously may become outdated. Website administrators perform regular security scans and vulnerability testing. Organizations document these maintenance activities as evidence of compliance efforts. Staff training helps ensure everyone handling website data understands privacy requirements. As regulations evolve, websites need corresponding updates to privacy notices and security features. Many healthcare organizations work with compliance consultants who specialize in digital healthcare requirements.

LuxSci vs. Zix Webroot

LuxSci vs. Zix Webroot: Choosing the Right HIPAA Compliant Email Provider

There are many crucial factors to consider when developing and executing successful healthcare communication campaigns. First and foremost, you must ensure the protected health information (PHI) under your organization’s care is handled securely, as mandated by Health Insurance Portability and Accountability Act (HIPAA) regulations, which begins with selecting the right HIPAA compliant email provider for your company’s needs.

With the right email services provider (ESP) in place, healthcare providers, payers, and suppliers can confidently use PHI in their patient and customer engagement campaigns – safe in the knowledge they’re aligned with HIPAA’s tight regulatory guidelines.

To help you choose the best HIPAA compliant email provider for your healthcare organization’s email outreach objectives, this post compares two of the most well-known HIPAA compliant services on the market: LuxSci and Zix Webroot (from here, simply referred to as Zix). 

Comparing each email provider’s performance on several criteria, we’ll help you decide which solution best fits the needs of your healthcare organization and will help you better engage with your patients and customers. 

LuxSci vs. Zix: Evaluation Criteria

In our evaluation of LuxSci vs. Zix, we’ll be using the following criteria: 

  • Data Security and Compliance: undoubtedly the most important factor when it comes to ensuring HIPAA-compliant email communication within healthcare organizations, this reflects the extent to which each platform secures sensitive patient data as per HIPAA’s regulations. 
  • Performance and Scalability: the email platform’s ability to facilitate high-volume email communication campaigns, which also, subsequently, encompasses the platform’s throughput and how well they’re able to scale in line with an organization’s needs. 
  • Infrastructure: if the email service provider has the necessary security infrastructure in place to both adequately safeguard PHI and support bulk email marketing campaigns.
  • Marketing Capabilities: if the platform provides features that allow you to personalize and refine your patient engagement strategies.
  • Ease of Use: how easy each email service is to use; a deceptively important factor in light of the urgent need for employee cyber threat awareness training. 
  • Other HIPAA-Compliant Products: if the platform offers complementary features that aid healthcare organizations with their broader patient engagement, and growth, objectives. 

Now that we’ve covered the criteria by which we’ll be assessing each email platform, let’s compare LuxSci vs Zix to determine which is the best fit for your company’s needs. 

LuxSci vs. Zix: How Do They Compare?

Data Security and Compliance

LuxSci prides itself on being a fully HIPAA-compliant email service provider, offering end-to-end, flexible, and automated encryption, giving it an advantage in the protection of patient data in the event of its exfiltration by cyber criminals. Additionally, LuxSci is HITRUST-certified, illustrating its additional commitment to data privacy legislation and the securing of PHI. 

Zix is also fully HIPAA-compliant and, consequently, enables the use of PHI to personalize your email communications. That said, Zix doesn’t offer as many encryption options as LuxSci. Most notably, Zix doesn’t enforce Transport Layer Security (TLS) encryption or enable automated encryption. The absence of these features means that a healthcare organization’s security teams must perform more manual oversight when it comes to encryption of PHI, increasing the chance of human error.

Performance and Scalability

While Zix supports large email campaigns and provides detailed reporting functionality, LuxSci is the more prudent choice for high-volume email marketing campaigns. 

LuxSci maintains the necessary infrastructure to ensure the reliable delivery of hundreds of thousands to millions of emails per month (i.e., throughput – 1000s of emails per hour), all while adhering to HIPAA’s strict guidelines on preserving patient privacy.

Infrastructure

In the same way that LuxSci have advantages over Zix on data security capabilities, it performs well in this category too, which makes sense, as the two factors are interwoven. 

While offering a range of customary multi-tenancy infrastructure setups, Zix doesn’t accommodate dedicated, or single-tenancy, infrastructure options – for companies who can’t afford to depend on the security postures of the companies with whom they share servers. Zix, in line with its ability to facilitate large patient or customer engagement campaigns, provides enterprise-scale scalability. 

Zix also provides high availability and robust disaster recovery capabilities, so healthcare organizations can retain their operational capabilities in the event of a cyber attack. Or, alternatively, an unforeseen physical disaster that compromises a company’s infrastructure (power outages, fires, storms, intentional damage, etc.).

That said, LuxSci possesses all these features in addition to more comprehensive single-tenancy options, scalability, and secure email hosting.

Marketing Capabilities

As with our comparisons of LuxSci against email platforms like Paubox and Virtru, it’s somewhat futile to compare each platform’s marketing capabilities – as neither LuxSci or Zix are marketing platforms, in the vein of Adobe Campaign or Oracle Eloqua, for example. 

That said. LuxSci provides a HIPAA compliant marketing solution, offering automation, for streamlining email marketing campaigns, and, personalization options, for more engaging email communication campaigns. 

Ease of Use

Both LuxSci and Zix perform admirably in this category, but the edge goes to Zix, as LuxSci implementations often involve the complexities that come with large-scale, high volume use cases.

LuxSci, however, is known for offering best-in-class customer support backed by HIPAA security experts, honed as a result of over 25 years of facilitating and supporting email communication strategies for healthcare organizations of all sizes. 

Other HIPAA-compliant Products

With secure texting functionality, secure forms for HIPAA compliant data collection, and secure file sharing, LuxSci ranks well in this category.  Zix, in contrast, provides only secure file sharing – though, because of Zix Webroot’s capabilities, offers superior secure file sharing to LuxSci.

Healthcare Email Threat Readiness Strategies

Are you up to date on the latest email security threats?

In this post, we share details from our just-released Email Cyber Threat Readiness Report, exploring the most effective ways to strengthen your healthcare organization’s email cyber threat readiness in 2025.

Let’s go!

Conduct Regular Risk Assessments 

To strengthen your company’s email security posture, you must first identify vulnerabilities in your infrastructure that malicious actors could exploit. Frequent risk assessments will highlight the security gaps in your email infrastructure and allow you to implement the appropriate strategies to mitigate threats.

A comprehensive email risk assessment should include:

  • Assessment of email encryption practices.
  • Review of email authentication protocols, i.e., SPF, DKIM, DMARC.
  • Evaluation of access control policies and practices.
  • Assessment of malware detection capabilities.
  • Audit of third-party integrations.
  • Testing of employee email threat awareness through simulated attacks to determine threat readiness and training needs.
  • Review of incident response and business continuity plans, especially, in this case, in regard to email-based threats.

A risk assessment may also involve the use of vulnerability scanning tools, which scan your email infrastructure looking for conditions that match those stored in a database of known security flaws, or Common Vulnerabilities and Exposures (CVEs). Alternatively, healthcare companies often employ the services of ethical, or ‘white hat’, hackers who carry out penetration tests, in which they purposely attempt to breach your email security measures to pinpoint its flaws.

​​Implement Email Authentication Protocols

As touched on above, enabling and correctly configuring the right email authentication protocols is an essential mitigation measure against phishing and BEC attacks, domain spoofing and impersonation, and other increasingly common email threats. Just as importantly, it allows recipient email servers to verify that a message is authentic and originated from your servers, which reduces the risk of your domain being blacklisted and your emails being directed to spam folders instead of the intended recipient’s inbox.

The three main email authentication protocols are:

  • DomainKeys Identified Mail (DKIM): adds a cryptographic signature to outgoing emails, allowing the recipient’s server to verify that the email was not altered in transit. 
  • Sender Policy Framework (SPF): allows domain owners to specify which servers are authorized to send emails on their behalf, mitigating domain spoofing and other forms of impersonation.
  • Domain-based Message Authentication, Reporting & Conformance (DMARC): builds on SPF and DKIM by establishing policies for handling unauthorized emails. It instructs the recipient email server to monitor, quarantine, or reject emails that fail authentication checks. 

Establish Robust Access Control Policies

Implementing comprehensive access control policies reduces the chances of ePHI exposure by restricting its access to individuals authorized to handle it. Additionally, access privileges shouldn’t be equal and should be granted based on the employee’s job requirements, i.e., role-based access control (RBAC).

Zero Trust Architecture (ZTA), in contrast, is a rapidly emerging, and more secure, alternative to RBAC. ZTA’s core principles are “least privilege”, i.e., only granting the minimum necessary access rights, and “never trust, always verify”, i.e., continually asking for the user to confirm their identity as the conditions of their session change, e.g., their location, the resources they request access to, etc. 

Enable User Authentication Measures

Because a user’s login credentials can be compromised, through a phishing attack or session hijacking, for instance, access control, though vital, only protects ePHI to an extent. Subsequently, you must require a user to prove their identity, through a variety of authentication measures – with a common method being multi-factor authentication (MFA).

Recommended by HIPAA, MFA requires users to verify their identity in two or more ways, which could include:

  • Something they know (e.g., one-time password (OTP), security questions)
  • Something they have (e.g., a keycard or security token)
  • Something they are (i.e., biometrics: retinal scans, fingerprints, etc.). 

What’s more, it’s important to note that the need to enable MFA will be emphasized to a greater degree when the proposed changes to the HIPAA Security Rule go into effect in late 2025.

Identify and Manage Supply Chain Risk

While on the subject of access control, one of the most significant security concerns faced by healthcare organizations is that several third-party organizations, such as vendors and supply chain partners, have access to the patient data under their care to various degrees. As a result, cybercriminals don’t have to breach your email security measures to access ePHI – they could get their hands on your patients’ data through your vendors.

Consequently, third-party risk management must be a fundamental part of every healthcare organization‘s email threat mitigation strategy.  This requires you to ensure that each vendor you work with has strong email security measures in place. In light of this, a HIPAA requirement is to have a business associate agreement (BAA) in place with each third party, or business associate, so you both formally establish your responsibilities in securing ePHI. 

Set Up Encryption for Data In Transit and At Rest

Encrypting the patient data contained in email communication is a HIPAA regulation, as it prevents its exposure in the event of its interception by a cybercriminal. You should encrypt ePHI both in transit, i.e., when being included in emails, and at rest, i.e., when stored in a database.

Encryption standards sufficient for HIPAA compliance include:

  • TLS (1.2 +): a commonly-used encryption protocol that secures email in transit; popular due to being ‘invisible’, i.e., simple to use.
  • AES-256: a powerful encryption standard primarily used to safeguard stored data, e.g., emails stored in databases or archives.
  • PGP: uses public and private key pairs to encrypt and digitally sign emails for end-to-end security.
  • S/MIME: encrypts and signs emails using digital certificates issued by trusted authorities.

Develop a Patch Management Strategy

One of the most common means of infiltrating company networks, or attack vectors, is exploiting known security vulnerabilities in applications and hardware. Vendors release updates and patches to fix these vulnerabilities, so it’s crucial to establish a routine for regularly updating and patching email delivery platforms and the systems and infrastructure that underpin them.


Additionally, vendors periodically stop supporting particular versions of their applications or hardware, leaving them more susceptible to security breaches. With this in mind, you must track which elements of your IT ecosystem are nearing their end-of-support (EOS) date and replace them with suitable, HIPAA-compliant alternatives.

Implement Continuous Monitoring Protocols

Continuously monitoring your IT infrastructure is crucial for remaining aware of suspicious activity in your email traffic and potential security breaches. Without continuous monitoring, cybercriminals have a prime opportunity to infiltrate your network between periodic risk assessments. 

Worse, they can remain undetected for longer periods, allowing them to move laterally within your network and access your most critical data and systems. Conversely, continuous monitoring solutions employ anomaly detection to identify suspicious behavior, unusual login locations, etc. 

Develop Business Continuity and Disaster Recovery Plans

The unfortunate combination of organizations being so reliant upon email communication, email threats being so prevalent, and the healthcare sector being a consistent target for cyber attacks makes a data breach a near inevitability rather than a mere possibility. 

Consequently, it’s imperative to develop business continuity and disaster recovery protocols so you can resume normal operations as soon as possible in the event of a cyber attack. An essential part of a disaster recovery plan is making regular data backups, minimizing the impact on the service provided to patients and customers.

Implement Email Threat Awareness Training for Employees

Healthcare organizations must invest in email threat awareness training for their employees, so they can recognize the variety of email-based cyber attacks they’re likely to face and can play a role in their mitigation.

Email threat awareness training should include:

  • The different email-based cyber threats (e.g., phishing), how they work, and how to avoid them, including AI-powered threats.
  • Who to inform of suspicious activity, i.e., incident response procedures.
  • Your disaster recovery protocols.
  • Cyber attack simulations, e.g., a phishing attack or malware download.

While educating your employees will increase their email threat readiness, failing to equip them with the knowledge and skills to recognize email-based attacks could undermine your other mitigation efforts.

HIPAA Compliant

What Cloud is HIPAA Compliant?

No cloud platform is inherently HIPAA compliant without proper configuration and implementation. Major cloud providers including AWS, Microsoft Azure, Google Cloud, and Oracle Cloud can support HIPAA compliance when properly configured and covered by a Business Associate Agreement (BAA). Healthcare organizations must implement appropriate security controls, access restrictions, and monitoring regardless of which cloud they select. The HIPAA compliance of any cloud environment depends on both provider capabilities and how organizations configure their cloud resources.

Cloud Vendor Healthcare Capabilities

Leading cloud platforms offer services that support healthcare applications when properly implemented. Amazon Web Services (AWS) provides numerous HIPAA eligible services with appropriate security features and BAA coverage. Microsoft Azure includes healthcare-focused compliance frameworks and security implementations that align with HIPAA requirements. Google Cloud Platform lists HIPAA eligible services in their compliance documentation with clear guidance for healthcare implementations. Oracle Cloud offers capabilities for healthcare organizations building compliant environments. These providers maintain physical security for their data centers while providing tools for customers to implement logical security controls.

BAA Coverage and Responsibilities

Healthcare organizations must obtain a Business Associate Agreement from their cloud provider before storing protected health information in the cloud. These agreements establish the cloud provider as a business associate under HIPAA regulations. Each major provider offers standardized BAAs covering their services, though coverage varies between providers. Not all services from a provider fall under BAA coverage – organizations must verify which services qualify. The BAA establishes shared responsibility for securing protected healthcare information (PHI), with the cloud provider handling physical security and infrastructure while healthcare organizations remain responsible for application security and access management.

Implementing Cloud Security Measures

Creating a HIPAA compliant cloud environment requires several security implementations. Encryption for data at rest and in transit protects information from unauthorized access. Identity and access management controls restrict system access to authorized personnel. Network security measures include virtual private networks, firewall rules, and segmentation to isolate healthcare data. Logging and monitoring systems track user activities and system events. Backup and disaster recovery processes maintain data availability. Organizations must document these security implementations during audits or assessments to be considered fully HIPAA compliant.

Service Model Compliance Divisions

Different cloud service models affect how compliance responsibilities are divided between providers and healthcare organizations. Infrastructure as a Service (IaaS) gives organizations more control but also more responsibility for security implementation. Platform as a Service (PaaS) provides pre-configured environments with some security features built in. Software as a Service (SaaS) includes more provider-managed security but less customization. Healthcare organizations must understand where their responsibilities begin and end in each model. Documentation should clearly establish which security controls fall to the provider versus the healthcare organization based on the selected service model.

Healthcare-Optimized Cloud Solutions

Some providers offer specialized cloud environments designed for healthcare workloads. These environments include pre-configured compliance controls aligned with HIPAA requirements. Examples include AWS Healthcare, Microsoft Cloud for Healthcare, Oracle Cloud Infrastructure for Healthcare, and Google Cloud Healthcare API. These offerings often include healthcare-focused data models, integration capabilities, and security frameworks. While these environments simplify compliance efforts, organizations still must implement appropriate configurations and policies. The specialized nature of these offerings can provide advantages for healthcare-focused workflows and data handling requirements.

Maintaining Cloud Compliance

HIPAA compliance in cloud environments requires continuous management rather than one-time implementation. Organizations need processes for regular security assessments of their cloud configurations. Cloud security posture management tools help identify potential compliance gaps. Staff require training on cloud security practices and HIPAA requirements. Change management procedures should evaluate compliance impacts before implementing cloud configuration changes. Documentation must remain current as cloud environments evolve. These ongoing management practices help maintain HIPAA compliance throughout the lifecycle of cloud-based healthcare applications.
