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:

The sender’s computer talks to the sender’s email or WebMail server to upload the message.
The sender’s email or WebMail server then talks to the recipient’s inbound email server and transmits the message to them.
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])
	by abc.luxsci.com (8.14.4/8.13.8) with ESMTP id r7JEfIkK030002
	(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:

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).
Each Received line documents what a server did and when.
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

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:

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.
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.
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.

Patient Engagement ROI: The Business Case for Secure Email in Healthcare

April 28, 2026
Pete Wermter

Every IT investment in healthcare today is being evaluated through a sharper lens.

Budgets are tighter. Expectations are higher. AI is the shiny object. Across healthcare organizations, leadership is asking the same question: how does this investment drive measurable results?

That’s where Patient Engagement ROI comes in, and where many traditional approaches fall short.

The Hidden Cost of Ineffective Communication

Patient engagement isn’t just a healthcare priority. It’s a financial one.

Missed appointments, gaps in care, and low response rates all translate directly into increased costs, operational inefficiencies, and a poor patient experience. Yet many organizations still rely on fragmented, manual, or non-personalized communication strategies.

Why?

For many, it’s because of uncertainty around HIPAA compliance, and what’s allowed and not allowed. Too often, healthcare IT and marketing teams avoid using valuable patient data to avoid security and compliance risks, especially over the email channel. The result is often generic outreach that fails to connect, and fails to deliver meaningful results, such as better health outcomes, fewer missed appointments, and increased sales.

How Secure Email Delivers ROI in Healthcare

Among all healthcare IT investments, secure email stands out for one reason: it directly impacts both patient engagement and staff and process efficiency.

With the right HIPAA-compliant marketing automation platform, secure email enables organizations to:

Deliver personalized, relevant messages using PHI data in their emails
Automate outreach at scale with triggered, engagement-driven campaigns
Improve patient response rates and adherence for better outcomes
Reduce manual workload across teams for greater productivity

This is where patient engagement ROI becomes tangible.

Instead of one-size-fits-all messaging, organizations can connect with patients based on unique needs and health conditions, such as appointments, care plans, preventative care reminders, new product needs, and more. And because it’s automated, these improvements scale without adding to workloads.

Turning Compliance into Better Outcomes and Growth

HIPAA is often viewed as a constraint. In reality, it’s an opportunity. If you have the right tools.

At LuxSci, we focus exclusively on secure healthcare communications, helping organizations safely unlock the value of their data and communications. Our solutions are designed to remove the friction between compliance and communication, so you don’t have to choose between security and growth.

With capabilities like flexible encryption, advanced segmentation, and high-volume delivery, secure email marketing becomes more than a safeguard, it becomes a growth driver.

And with industry-leading security performance and recognition, organizations can trust that their communications are protected at every level with LuxSci.

Scaling Patient Engagement ROI with Automation

The real power of secure email comes when it’s combined with automated healthcare workflows.

HIPAA compliant marketing automation allows you to build multi-step, data-driven patient journeys that run continuously in the background, taking adaptive steps based on each individual’s email engagement activity. This can include:

Appointment reminders that reduce no-shows
Follow-up communications that improve outcomes
Preventative care outreach for check-ups, annual test and care reminders
New product offers, upgrades and promotions
Educational email campaigns that drive long-term engagement and better health

Each interaction is an opportunity to improve both patient experience and your financial performance. Over time, these incremental gains compound, resulting in significantly higher patient engagement that delivers real value to your business.

Why Act Now?

Healthcare organizations can no longer afford IT investments that don’t deliver clear, measurable value. Secure email, powered by HIPAA compliant marketing automation, offers one of the most direct paths to improving engagement, efficiency, and outcomes, all while maintaining the highest standards of security.

What Is B2B Marketing in Healthcare?

April 27, 2026
Erik Kangas

B2B marketing in healthcare describes the promotion of products and services to healthcare businesses rather than to patients or the public. The audience can include provider groups, payers, laboratories, medical suppliers, health technology firms, and service companies working across the sector. The work calls for a more measured approach than many other business categories because buying decisions tend to involve several stakeholders, internal review, and close attention to data handling, workflow impact, and commercial fit. Good execution depends on clear communication, useful content, and a strong sense of how healthcare organizations evaluate change.

Why healthcare buying requires a different approach

Healthcare companies rarely move through a buying process in a straight line. One person may open the conversation, though several others can influence whether it goes any further. Finance may want a clearer commercial case. Operations may focus on staffing, efficiency, and implementation pressure. IT may look at access, system fit, and data management. Compliance teams may review privacy implications or contractual language. B2B marketing in healthcare works better when the writing reflects those realities early. Buyers are looking for material that helps them assess risk, discuss options internally, and move forward with fewer unanswered questions.

A Difference in stakeholder priorities

A single account can contain several audiences at once. That is part of what makes this area demanding. A hospital operations leader may care about throughput and day to day workflow. A payer executive may be more interested in administrative efficiency or review times. A supplier may focus on coordination, ordering processes, or communication across partner relationships. Content becomes stronger when it takes those different perspectives seriously. The message does not need to become overly technical. It needs enough accuracy and relevance for each reader to feel that the company understands the conditions attached to their role.

Why credibility matters in every channel

Healthcare buyers tend to read promotional material carefully. They notice vague claims, inflated language, and unsupported promises very quickly. That is why credibility has to be built into the writing itself. A clean explanation of a business problem can carry real weight. A grounded case example can help a reader picture how a solution would work in practice. Clear language around implementation, support, privacy, or service structure can also help keep the conversation moving. When protected health information enters the picture, HIPAA may become part of the review as well, especially for companies handling regulated data or supporting covered entities and business associates.

Content to support real decisions

The most useful assets in this space are the ones that help buyers think more clearly. An article can frame a problem in a way that supports internal discussion. An email sequence can keep a company visible while review is taking place. A service page can answer practical questions before a meeting is booked. B2B marketing in healthcare gains traction when content has a clear job and a clear reader. That focus usually produces stronger engagement than broad copy built around generic thought leadership language. Buyers respond well to material that respects their time and gives them something worth passing along.

What strong performance looks like

Success in healthcare is rarely captured by surface numbers alone. Traffic and opens may show that content has reached people, though those signals do not say much on their own about buying intent. Better indicators include repeat visits from the same organization, replies from relevant contacts, deeper engagement with security or implementation pages, and growing activity across several stakeholders in one account. Those patterns can tell commercial teams where interest is becoming more serious. B2B marketing in healthcare proves its value when it helps those teams follow up with better timing, better context, and material that fits the next stage of evaluation.

What Is B2B Medical Marketing?

April 27, 2026
Erik Kangas

B2B medical marketing is the promotion of products and services to medical organizations, rather than to patients or general consumers. The audience can include provider groups, laboratories, payers, health technology companies, medical manufacturers, and service firms that sell into the healthcare space. The work involves more scrutiny than many other business sectors because buying decisions are reviewed through operational, financial, legal, and data related lenses. That environment shapes the way messages are written, the way proof is presented, and the pace at which commercial relationships develop.

Where B2B medical marketing fits in healthcare

Medical companies rarely buy on impulse. A new platform, service, or product may affect staff workflows, procurement planning, record handling, contract review, or coordination between teams. For that reason, B2B medical marketing sits close to the practical side of business decision making. Good content helps a buyer assess whether something will work inside an existing organization. It gives shape to the problem, explains the offer in plain terms, and provides enough context for internal discussion. In a medical setting, that matters because a single contact may show interest while several others influence whether the conversation continues.

Why the buying process feels slower

The pace of healthcare purchasing can frustrate vendors that are used to quicker decisions. Interest does not always translate into movement because the next step may depend on approval from finance, operations, IT, procurement, or compliance. Each group reads with a different priority in mind. An operations lead may look for staffing impact. An IT team may focus on access controls, system fit, and data use. Finance may ask whether the commercial case is persuasive enough to justify more review. B2B medical marketing works best when content reflects those realities from the start. Messages that feel rushed or overwritten tend to lose ground early.

Trust and proof carry weight

Medical buyers are used to reading claims with care. They want to know what the service does, how it fits into day to day work, and what kind of burden it may place on the people using it. That is why trust has to be earned through the material itself. Clear examples help. Credible case studies help. Sound explanations of process, security, implementation, or support also help because they answer the questions serious buyers are already asking. When privacy or protected health information enters the picture, references to HIPAA and related data handling expectations may also become part of the evaluation. B2B medical marketing gains traction when the language sounds careful, informed, and accountable on every page.

Content needs a job to do

A medical buyer reading an article, email, or landing page is usually looking for something useful rather than something flashy. The content may need to explain a workflow issue, support an internal conversation, prepare a reader for a product discussion, or clarify how a service would be introduced. That practical role should shape the writing. B2B medical marketing is stronger when each asset has a clear purpose and a clear reader. One article may help an operations contact define a bottleneck. Another may help a compliance stakeholder understand how data is handled. Another may give procurement a cleaner view of scope and process. Content works harder when it can travel inside the account and still make sense to the next person who reads it.

What good measurement looks like

Performance in this area is not captured by one metric. Page views and open rates may show that something has attracted attention, though they do not say much on their own about buying intent. Better signs come from repeat visits from the same account, deeper engagement with implementation or security pages, replies from people with decision making authority, and movement from light interest to active review. B2B medical marketing earns its value when it helps commercial teams see where attention is turning into evaluation. That is where better timing, stronger follow up, and sharper account insight begin to matter.

Zero Trust Email Security in Healthcare: A Requirement for Sending PHI?

April 15, 2026
Pete Wermter

As healthcare organizations embrace digital patient engagement and AI-assisted care delivery, one reality is becoming impossible to ignore: traditional perimeter-based security is no longer enough. Email, still the backbone of patient and operational communications, has become one of the most exploited attack surfaces.

As a result, Zero Trust email security in healthcare is moving from buzzword to necessity.

At LuxSci, we see this shift firsthand. Healthcare providers, payers, and suppliers are no longer asking if they should modernize their security posture, but how to do it without disrupting care delivery or patient engagement.

Our advice: Start with a Zero Trust-aligned dedicated infrastructure that puts you in total control of email security.

Let’s go deeper!

What Is Zero Trust Email Security in Healthcare?

At its core, Zero Trust email security in healthcare applies the principle of “never trust, always verify” to every email interaction involving protected health information (PHI).

This means:

Continuous authentication of users and systems
Device and environment validation before granting access
Dynamic, policy-based encryption for every message
No implicit trust, even within internal networks

Unlike legacy approaches that assume safety inside the network perimeter, Zero Trust treats every email, user, and endpoint as a potential risk.

Why Email Is a Critical Gap in Zero Trust Strategies

While many healthcare organizations have begun adopting Zero Trust frameworks for network access and identity, email often remains overlooked.

This is a major problem.

Email is where:

PHI is most frequently shared
Human error is most likely to occur
Phishing and impersonation attacks are most effective

Without a Zero Trust email security approach, organizations leave a critical gap in their defense strategy, one that attackers can actively exploit.

Healthcare Challenge: Personalized Communication and PHI Risk

Modern healthcare ecosystems are highly distributed:

Care teams span multiple locations
Third-party vendors access sensitive systems
Patients expect digital, personalized communication

This creates a complex web of PHI exchange—much of it through email.

At the same time, compliance requirements like HIPAA demand that PHI email security is addressed at all times.

The result is a growing tension between:

Security and compliance
Usability, engagement, and better outcomes

From Static Encryption to Intelligent, Adaptive Protection

Traditional email encryption methods often rely on:

Manual triggers
Static rules
User judgment

This introduces risk. A modern zero trust email security in healthcare model replaces this with:

Automated encryption policies based on content and context
Flexible encryption methods tailored to recipient capabilities – TLS, Portal Fallback, PGP, S/MIME
Seamless user experiences that human error – automated email encryption, including content

At LuxSci, our approach to secure healthcare communications is built around this philosophy. By automating encryption and providing each customer with a zero trust-aligned dedicated infrastructure, organizations can protect PHI without relying on end-user decisions or the actions of other vendors on the same cloud, significantly reducing risk while improving performance, including email deliverability.

Aligning Zero Trust with HIPAA and Emerging Frameworks

Zero Trust is not a replacement for compliance, it’s an enabler. A well-implemented Zero Trust approach helps organizations:

Meet HIPAA requirements for PHI protection
Reduce the likelihood of breaches
Strengthen audit readiness and risk management

More importantly, it positions healthcare organizations to align with emerging cybersecurity frameworks that increasingly emphasize identity, data-centric security, and continuous verification.

PHI Protection Starts with Email

Zero Trust is no longer a conceptual framework, it’s becoming the operational standard for healthcare IT, infrastructure, and data security teams.

But success depends on execution. Email remains the most widely used, and vulnerable, communication channels in healthcare. Without addressing it directly, Zero Trust strategies will fall short.

Here are 3 tips to stay on track:

Treat every email as a potential risk
Automate encryption at scale – secure every email
Enable personalized patient engagement with secure PHI in email

At LuxSci, we believe that HIPAA compliant email is the foundation for the future of secure healthcare communications, protecting PHI while enabling better patient engagement and better outcomes.

How To Overcome Email Encryption Challenges in Healthcare

April 14, 2025
Pete Wermter

Encryption is a critical security measure for protecting electronic protected health information (ePHI) included within email communications, and a key technical safeguard under the HIPAA Security Rule. However, despite its efficacy in helping protect sensitive patient data from malicious actors, encryption can be difficult to successfully implement.

Technical complexity, user resistance, and compatibility issues across different email systems can emerge as persistent problems, leading to frustration, risky workarounds, and, ultimately, increased risk of ePHI exposure and compliance violations. Without thoughtful deployment and support, encryption can become a barrier to successful secure email communication in healthcare, as opposed to a measure that underpins it.

To help you ensure secure, HIPAA compliant email communication, this post discusses the main encryption challenges you’re likely to encounter, how they can diminish your email security posture, and the measures you can take to overcome them.

What Is Email Encryption?

Before we discuss the most frequent email encryption challenges faced by healthcare organizations, here’s a quick refresher on what email encryption is and why it’s so important for securing sensitive patient data.

Email encryption is the process of scrambling the content of a message to make it unreadable as it’s sent to recipients or stored in a database. Only the intended recipient, who has the encryption key, can decrypt the email and access the data within.

Consequently, in the event an encrypted message is intercepted by malicious actors in transit or exfiltrated from a data store during a security breach, they won’t be able to make sense of it. This renders any ePHI included in the message unintelligible and, therefore, worthless, adding another layer of security that preserves patient privacy – and keeps your business safe.

Common Email Encryption Challenges

Let’s move on to detailing some of the most frequent encryption challenges that must be overcome by healthcare organizations to ensure secure email communication and HIPAA compliance.

Decrypting Messages Is Too Difficult

The more difficult or drawn out it is for recipients to decrypt their email messages, the more likely they’ll simply go unread or end up deleted. If the decryption process is too cumbersome, which could include requiring a user to log into a separate site (i.e., a web portal), verify their identity multiple times, create a new account, or install additional software, it adds complexity. This can drive users to seek workarounds or cut corners, such as having information sent to them through unsecured channels, which puts your company at risk.

Similarly, email clients, browsers, and security settings may impact the decryption process, causing compatibility issues that prevent users from accessing their messages. Within a healthcare setting, where timely communication is crucial, such obstacles can disrupt workflows, slow down patient care, and lead to HIPAA compliance violations if users resort to unencrypted alternatives.

Encryption that Requires Manual Intervention

Some email encryption tools require users to manually encrypt messages. If users forget to apply encryption or misconfigure settings, sensitive patient data could be exposed, leading to compliance violations and ePHI exfiltration.

For employees who handle ePHI and need to send encrypted emails, remembering to enable encryption (vs. automated encryption) is an extra step that introduces the risk of human error into the process. To offer a related, and more relatable, example: how many times have you forgotten to include an attachment when sending an email, even when referencing the attachment in the message? It’s all too easily done. In the same way, an inexperienced, tired, or distracted user could simply neglect to turn on or correctly configure encryption before sending an email, putting patient data at risk.

Increased IT and Administrative Overhead

The two email encryption challenges outlined above contribute to a third overarching difficulty for healthcare organizations: an increased workload for its IT, security and operations teams.

First of all, IT, security and operations must establish and continuously enforce encryption policies, configuring rules that ensure sensitive patient data is encrypted while non-sensitive, business communication continues to flow unobstructed. Misconfigured policies can cause over-encryption, resulting in user inaccessibility and disruptions, or under-encryption, leading to exposure of ePHI and HIPAA compliance violations.

Second, IT support teams must troubleshoot user issues: namely employees and external recipients who are unfamiliar with encryption protocols and need support in overcoming difficulties in message decryption. These could be caused by compatibility issues between different email clients or systems, expired or missing digital certificates, incorrect key exchanges, or confusion surrounding accessing encrypted messages through portals or attachments.

Lastly, IT and governance teams must keep up-to-date with changing regulatory updates and email security threats. As compliance requirements evolve, healthcare organizations must reassess encryption standards, upgrade outdated protocols, and ensure that their workforce adheres to best practices. Without an adequate strategy and the right systems in place, managing encryption can become a constant drain on IT bandwidth, taking personnel away from other aspects of their work that contribute to patient care.

Effective Strategies For Email Encryption

Having discussed the most common encryption challenges and how they can impact a company’s email security posture, let’s look at some of the most powerful mitigation strategies, which will improve the email encryption experience for both senders and recipients.

Balance Security With Ease of Use

To overcome the challenges of user inaccessibility, human error, and excessive administrative overhead, healthcare organizations must balance the ease of use of their encryption solutions with the level of security they provide.

While opting for the most secure encryption protocols intuitively seems like the best option, extra security often comes at the expense of usability, which can render the encryption irrelevant if users decide to circumvent it altogether, as outlined earlier. Instead, it’s essential to evaluate the sensitivity of message content and select a corresponding level of encryption.

Moving onto practical technical examples, Transport Layer Security (TLS) is a widely used email encryption standard, thanks to its ease of implementation and use, i.e., once activated, no further action is required by the user to encrypt the message content. However, TLS only encrypts ePHI in transit, i.e., when being sent to recipients, which may prove insufficient for highly sensitive patient data.

In contrast, encryption protocols such as Secure/Multipurpose Internet Mail Extensions (S/MIME), AES-256 and Pretty Good Privacy (PGP) provide more comprehensive encryption, safeguarding the ePHI contained in email communications both in transit and at rest, i.e., when stored in a database. Now, while this makes them more effective at securing patient data and achieving HIPAA compliance, these standards are more complicated to implement and to use than TLS encryption.

S/MIME requires users to obtain and install digital certificates from a Certificate Authority (CA), which verifies their respective identities and provides the public key for encryption. Consequently, both the sender and recipient must have valid certificates; if either party’s certificate is revoked or expires, they won’t be able to encrypt or decrypt the message, respectively.

With PGP, meanwhile, users must manually generate and exchange public/private keys. This offers greater flexibility than S/MIME but requires careful key management, which can be confusing for non-technical users. If a recipient doesn’t have the sender’s public key, they won’t be able to decrypt the message. Additionally, both S/MIME and PGP require a public key infrastructure (PKI), which can add considerable administrative overhead, particularly in regards to the management of certificates, public keys, and user credentials.

Accounting for this, healthcare organizations can balance security with accessibility by employing a tiered encryption strategy: using TLS for lower-risk communication while opting for S/MIME or PGP for more sensitive communications.

Enable Automatic Encryption

Subsequently, the challenge of balancing security with accessibility can be remediated by deploying an email delivery platform that not only removes the need for manual user intervention but also automatically applies the appropriate encryption standard based on message content and delivery conditions. Rather than relying on users to choose the correct method—or worse, bypass encryption altogether—modern email solutions like LuxSci can intelligently enforce encryption without affecting the user experience.

Many healthcare companies rely on TLS encryption because it eliminates the need for encryption keys or certificates, additional log-ins, etc. For this reason, it’s often referred to as ‘invisible encryption’ for its lack of effect on the user experience.

However, to be most effective, both the sender’s and recipient’s email servers must support enforced TLS (i.e., TLS 1.2 and above). In the event the recipient’s email server doesn’t support TLS, the email message will be delivered unencrypted or fail to send altogether, depending on the server configurations. Additionally, once the email is delivered to the recipient’s inbox, unless the recipient’s email infrastructure encrypts messages at rest, it will be stored in an unencrypted format.

Consequently, while TLS is ideal for email messaging that doesn’t contain highly sensitive ePHI, it’s insufficient for all healthcare communication. To ensure the secure and HIPAA compliant inclusion of patient data in emails, healthcare organizations should opt for an email solution that supports automated, policy-based encryption, which can upgrade to S/MIME or PGP when necessary. This offers the combined benefits of optimal ePHI security, minimal administrative burden, and removing the need for staff intervention.

Invest in Employee Education

While a flexible encryption policy and deploying email solutions that support automation will go a long way towards overcoming email encryption challenges, these efforts can still be undermined if users aren’t sufficiently educated on their benefits and use. For this reason, it’s crucial that healthcare companies take the time to educate their employees on both the how and why of email encryption.

Even the most advanced encryption systems can fail if employees don’t understand how to use them properly, as well as what to look out for in their day-to-day email use. Some aspects of email encryption, such as recognizing secure message formats or troubleshooting delivery issues, may still require user awareness. With this in mind, employee training programs should focus on recognizing when additional encryption measures are necessary, how to ask for assistance, the dangers of unsecured channels, and how to report suspicious activity in addition to the practical aspects of using your email delivery platform.

Is GoDaddy HIPAA Compliant?

March 25, 2025
Erik Kangas

GoDaddy hosting services are not HIPAA compliant by default, as the company does not offer Business Associate Agreements (BAAs) for its standard hosting plans, which prevents healthcare organizations from legally storing protected health information on these platforms. While GoDaddy provides security features like SSL certificates and malware scanning, these measures alone do not meet the requirements for HIPAA compliance. Healthcare organizations need hosting providers that specifically support healthcare regulatory requirements.

GoDaddy’s Standard Hosting Services

GoDaddy’s regular web hosting packages lack several elements needed for HIPAA compliance. These plans typically use shared server environments where multiple websites operate on the same physical hardware, creating potential data separation issues. The standard backup systems do not guarantee the encryption required for protected health information. User access controls in basic hosting plans lack the detailed permission settings and authentication measures that HIPAA demands. GoDaddy’s terms of service for regular hosting plans do not address healthcare data requirements or regulatory protections. Healthcare organizations often mistakenly assume that adding SSL certificates to GoDaddy hosting creates HIPAA compliance.

Business Associate Agreement Availability

Healthcare organizations must obtain a Business Associate Agreement before using any service provider for protected health information. GoDaddy does not offer BAAs for its standard shared, VPS, or dedicated hosting services. Without this agreement, healthcare providers cannot legally store patient information on GoDaddy platforms regardless of added security measures. The company’s support documentation does not mention HIPAA compliance or BAA availability for any of its hosting products. This limitation reflects GoDaddy’s focus on general business websites rather than regulated industries with strict data protection requirements. Healthcare organizations may assume incorrectly that larger hosting providers automatically support HIPAA needs.

GoDaddy’s Security Features

GoDaddy includes certain security features that, while valuable, fall short of HIPAA requirements. SSL certificates encrypt data during transmission but don’t address storage encryption needs. Malware scanning helps protect websites from common threats but doesn’t meet the continuous monitoring standards for healthcare data. The available backup options lack guarantees about encryption or access controls for the backup files themselves. Account permissions do not provide the granular access controls needed for healthcare applications. Server update processes may not meet the timely patching requirements for systems handling sensitive information. These limitations make GoDaddy unsuitable for websites containing patient data despite its general security offerings.

HIPAA Compliant Hosting Alternatives

Healthcare organizations have several hosting alternatives that specifically address HIPAA requirements. Specialized HIPAA compliant hosting providers include appropriate security measures and offer BAAs as standard practice. These providers implement server-level encryption, detailed access logging, and physical security controls designed for healthcare data. Cloud platforms like AWS, Microsoft Azure, and Google Cloud offer HIPAA compliant configurations with available BAAs. Many healthcare-focused hosting companies provide compliance support services beyond just server space. The cost for these services usually exceeds standard GoDaddy plans but includes necessary compliance features.

Appropriate Uses for GoDaddy Services

GoDaddy hosting remains suitable for certain healthcare-related websites that don’t involve protected health information. Informational healthcare websites displaying services, provider biographies, and location details can use standard hosting. Marketing materials and educational resources without patient data fall outside HIPAA requirements. Healthcare organizations sometimes maintain separate websites—placing public information on standard hosting while keeping patient portals on HIPAA compliant platforms. This separation reduces costs while maintaining appropriate compliance for protected information. Organizations using this approach need clear policies about what information appears on which platform.

Evaluation Criteria for Hosting Services

Healthcare organizations should evaluate potential hosting providers using consistent criteria. Providers must offer Business Associate Agreements addressing their responsibilities under HIPAA. Hosting environments need encryption for data both during transmission and while stored on servers. Access controls should limit system access to authorized personnel with appropriate permissions. Audit logging capabilities must track all user activities and system events. Physical security measures for data centers should include restricted access and environmental protections. Regular security assessments help identify potential vulnerabilities. Organizations benefit from documenting their evaluation process to demonstrate due diligence in selecting HIPAA compliant hosting partners.
