HIPAA Security Rule Update: Email Encryption Rule Delayed to 2027

July 22, 2026
Pete Wermter

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.

HIPAA Security Rule Email Encryption Requirements

July 8, 2026
Tom Deeb

Your Email Platform Is Becoming Critical Healthcare Infrastructure

July 1, 2026
Pete Wermter

Most healthcare organizations view email as a utility, a necessary tool for sending messages between staff, communicating with patients, sending out newsletters, connecting workflows, and so on. Historically, IT teams focused on keeping it running, security teams worried about phishing, and compliance teams made sure sensitive emails were encrypted.

Today, however, that view is rapidly becoming outdated.

Email has evolved into one of healthcare’s most critical digital infrastructure components, and also one of it’s biggest security threats. It’s a core channel for patient engagement, care coordination, revenue cycle operations, digital marketing, remote monitoring, and increasingly, AI-powered communications. The organizations that recognize this shift are building communications platforms designed for security, performance, automation, and growth. With the new HIPAA Security Rule requiring email encryption on the horizon, those companies that don’t may find themselves constrained by systems that were never intended to support modern healthcare.

Email Is No Longer Just a Messaging Tool

Healthcare organizations now depend on email to support dozens of mission-critical workflows every day.

Patients receive appointment reminders, registration instructions, imaging results, billing notifications, Explanation of Benefits (EOBs), prescription updates, preventive care reminders, patient education, and post-discharge follow-up. Marketing teams deliver personalized wellness campaigns and service line promotions. Clinical systems generate transactional notifications. Revenue cycle teams rely on secure digital communications to accelerate payments and reduce paper costs.

For many organizations, mission-critical patient communications flow through email every month.

When viewed collectively, email is more than a simple communications channel. It has become operational infrastructure with high levels of security needed and increasing compliance requirements.

The Stakes Continue to Rise

As healthcare becomes more digital, every communication carries greater business and clinical importance.

A delayed billing email may postpone payment. A failed appointment reminder can increase no-show rates. An undelivered care management message may impact patient outcomes. A misconfigured security policy can expose protected health information (PHI). Poor deliverability can undermine expensive patient engagement initiatives before they ever reach the inbox.

These are no longer isolated IT issues. Email can affect revenue, patient satisfaction, operational efficiency, compliance, and organizational reputation.

Today’s healthcare leaders require email infrastructure to provide the same reliability and visibility they demand from electronic health records, identity management systems, and other core infrastructure.

AI Is Raising the Bar Even Higher

There’s little doubt that artificial intelligence (AI) promises to transform patient communications.

Healthcare organizations everywhere are exploring AI-generated patient education, personalized outreach, intelligent scheduling, multilingual communications, and automated follow-up programs.

But AI also increases the importance of the underlying communications infrastructure.

Generating more personalized emails means little if organizations cannot:

Automatically protect PHI.
Apply consistent security policies.
Maintain complete audit trails.
Deliver messages reliably.
Integrate with EHRs, RCM and CRM platforms, and customer data platforms.
Demonstrate compliance during an audits.

In many ways, AI amplifies both the opportunities and the risks. Your email platform can help determine whether AI initiatives succeed or create new compliance and operational challenges.

Infrastructure Matters More Than Features

Healthcare buyers have traditionally evaluated email platforms based on individual features such as encryption, spam filtering, or secure portals.

Those capabilities remain important, but they no longer tell the whole story.

Today’s healthcare organizations should be evaluating communications platforms the same way they evaluate any mission-critical infrastructure.

Questions increasingly include:

Can it support both transactional and marketing communications?
Does it automatically enforce security policies without relying on user decisions?
Can it integrate with EHRs, CRM systems, CDPs, and business applications?
Will it scale during peak communication periods?
Does it provide detailed audit logging and reporting?
Can it adapt as regulatory expectations evolve?
Does it maintain high deliverability at enterprise scale?
Does it support single-tenant dedicated infrastructure for high performance and increased security?

These infrastructure characteristics often determine long-term success far more than any single feature comparison.

Email and the Future Of Secure Healthcare Communications

Healthcare is steadily moving toward a world where nearly every patient interaction is digital, personalized, and data-driven.

Healthcare leaders often ask whether they need a more secure email solution. That may be the wrong question.

The better question is whether their communications infrastructure is ready for where healthcare is headed over the next decade.

The HIPAA Security Rule Missed Its May Deadline — Here’s What We Know

June 9, 2026
Pete Wermter

The proposed HIPAA Security Rule update has become one of the most closely watched healthcare compliance developments in recent years. Designed to strengthen cybersecurity protections for electronic protected health information (ePHI), the proposal could significantly reshape how healthcare organizations approach risk management, ePHI encryption, and mandatory email encryption requirements.

A final rule was expected as early as May 2026. However, that deadline has now passed without publication from the U.S. Department of Health and Human Services (HHS) Office for Civil Rights (OCR).

So, what happens next—and what should healthcare IT directors, CISOs, and compliance officers do now?

Where Things Stand Today

The HIPAA Security Rule Notice of Proposed Rulemaking (NPRM) was published on January 6, 2025, with the goal of strengthening cybersecurity protections for ePHI in response to escalating ransomware attacks, healthcare breaches, and growing concerns about cyber resilience across the healthcare sector.

The proposal generated thousands of public comments from healthcare providers, payers, business associates, technology vendors, and industry groups. OCR has spent much of the past year reviewing this feedback and evaluating the operational and financial impact of the proposed changes.

Although the Spring Unified Regulatory Agenda identified May 2026 as a target date for a final rule, that milestone came and went without publication. As of June 2026, the proposed HIPAA Security Rule update remains under review.

While some organizations may be tempted to take a wait-and-see approach, the missed deadline should not be interpreted as a signal that the initiative has stalled. If anything, the proposal offers valuable insight into the future direction of healthcare cybersecurity regulation.

The Growing Focus on Mandatory Email Encryption

One of the most discussed aspects of the proposed HIPAA Security Rule update is encryption.

Under the current HIPAA Security Rule, encryption is generally classified as an “addressable” implementation specification. Organizations can choose alternative safeguards if they document and justify their decisions through a risk analysis process.

The proposed changes would significantly reduce that flexibility. Instead, many security safeguards, including encryption controls, would become more prescriptive and difficult to avoid.

While the final language has not yet been released, healthcare organizations should pay close attention to the proposal’s clear message: protecting ePHI through encryption is increasingly viewed as a baseline cybersecurity requirement.

This is particularly important for email communications.

Email remains one of the most widely used communication channels in healthcare, supporting everything from patient engagement and care coordination to billing, scheduling, and marketing communications. As regulators continue to focus on reducing data breach risks, mandatory email encryption is emerging as a likely area of increased scrutiny.

What Healthcare Organizations Should Do Now

The current delay creates an opportunity, not a reason to postpone action.

Healthcare organizations can begin preparing for likely requirements today by evaluating the security controls highlighted throughout the proposed rule.

Key areas to review include:

Encryption of ePHI across systems and communications channels
Comprehensive asset inventories and ePHI data mapping
Enhanced risk analysis and risk management processes
Multifactor authentication (MFA)
Vulnerability scanning and penetration testing
Incident response planning and testing
Backup and recovery procedures
Email security and secure email encryption practices

Organizations that proactively strengthen these areas now will be better prepared regardless of the final rule’s implementation timeline.

Why Secure Email Encryption Should Be a Priority

For many healthcare organizations, email remains one of the largest compliance and security risks.

Human error, misdirected messages, phishing attacks, and inconsistent encryption practices continue to contribute to breaches involving protected health information. As a result, secure email encryption is increasingly becoming a foundational component of healthcare cybersecurity strategies.

Organizations that rely on manual encryption processes or employee judgment alone may find it difficult to meet evolving regulatory expectations.

Instead, healthcare organizations should look for solutions that automate encryption decisions, reduce user error, and provide flexibility based on the sensitivity of the communication.

At LuxSci, we have long believed that security and usability must work together. We are 100% focused on secure healthcare communications, helping healthcare providers, payers, and suppliers protect sensitive data while improving patient and customer engagement. Our proven secure email solutions, used by leading companies including Athenahealth, 1-800 Contacts, and Hinge Health, help organizations protect ePHI with automated encryption capabilities that support both compliance and operational efficiency. Our unique SecureLine encryption technology enables organizations to apply the appropriate level of protection while maintaining a seamless experience for patients, customers, and staff.

For organizations already using Microsoft 365 or Google Workspace, LuxSci Secure Email Gateway can add HIPAA-compliant email security and encryption without requiring users to change their existing workflows. This approach helps reduce risk, while preserving productivity and user adoption.

The Bottom Line

The HIPAA Security Rule final rule may have missed its anticipated May deadline, but the cybersecurity challenges driving the proposal remain very real.

The OCR is still expected to make the rule change, which could require mandatory encryption of ePHI by early 2027.

The time to prepare is now!

Healthcare organizations should view the proposed HIPAA Security Rule update as an advance warning of where regulatory expectations are heading. Stronger cybersecurity controls, enhanced risk management, ePHI encryption, and mandatory email encryption requirements are all likely to remain central themes in future compliance efforts.

The organizations that begin preparing now will not only be better positioned for future regulatory changes, but will also strengthen their ability to protect patient data, reduce risk, and build trust in an increasingly challenging threat landscape.

At LuxSci, we’re proud to support the healthcare industry’s ongoing digital transformation through secure healthcare communications. Our HIPAA-compliant solutions for secure email, email marketing, and forms empower organizations to safely use and protect PHI, while delivering better patient experiences and outcomes.

How Insurers Can Save Millions Per Month with Secure Email EOBs

June 10, 2025
Pete Wermter

Have you looked into what it’s costing your company to snail mail EOBs these days?

EOBs give an individual an increased understanding of their insurance coverage, the cost of care, and their out of pocket expenses. As a result, it’s absolutely critical that health insurers deliver EOBs quickly and effectively.

However, the most commonly used method for sending out EOBs, traditional mail or snail mail, has several drawbacks that can prevent important information about healthcare coverage from reaching people in a timely manner – not to mention the high cost insurers take on to send them. This can leave policyholders in the dark about their healthcare coverage, which can lead to confusion and dissatisfaction with their insurance provider when they receive an unexpected medical bill.

Furthermore, because EOBs contain the protected health information (PHI) of policyholders or members, insurers are bound by HIPAA (the Health Insurance Portability and Accountability Act) regulations to ensure their secure delivery. Consequently, the risks inherent to sending paper EOB statements in the mail not only have security implications but also potential consequences for non-compliance.

With all this in mind, this post discusses why healthcare insurers should send EOBs to their policyholders via secure email instead of traditional mail. We detail the various benefits of making the switch to email EOBs, which include enhanced security, better adherence to compliance regulations, higher deliverability rates, and significant cost savings.

Security Benefits

Insurance companies that send out EOBs via email as opposed to traditional mail are less likely to be at risk for a data breach or leak of PHI. Firstly, sending an EOB via email drastically decreases the risk of interception. When sent in paper form, an EOB could be:

Lost, stolen or damaged in transit
Delivered to the wrong address
Not properly deposited in a letter or mailbox, then stolen
Intercepted within the intended address by another individual who lives at or has access to the residence.

Conversely, as detailed later in this post, email allows for various controls and processes, which mitigate the risks of unsuccessful message delivery.

Additionally, secure, HIPAA compliant email provides data encryption, which safeguards the sensitive patient data within EOBs during transmission and at rest by rendering it unreadable to malicious actors who might intercept it or gain access to it. Physical mail, in contrast, offers no such protection, as someone who intercepts a paper EOB notice can simply open it and freely read its contents.

Finally, secure email delivery platforms, such as LuxSci, feature identity verification and access controls that enable healthcare insurers to restrict access to PHI, limiting its exposure. Similarly, HIPAA compliant email also provides auditing logging capabilities to track access to patient data, to quickly identify the source of security breaches.

Increased Delivery

Once a person opts-in, sending an EOB by email greatly increases its deliverability, up to 98% or more – almost instantly. By better ensuring a policyholder receives their EOBs, healthcare insurers increase the chance of successfully communicating the intended information they contain, namely, the cost of a service and how much they’re required to cover.

Additionally, the ability to track secure email in near real-time also enhances its deliverability, as it allows organizations to determine the cause of delivery failure and make subsequent attempts to get the EOB delivered. At the same time, the process of determining the reason for the message failure may also reveal security concerns; a process that is very difficult, if not impossible, to achieve with traditional physical mail.

Radical Cost Savings

Simply put, sending EOBs via email instead of traditional mail can save health insurers massive amounts of money. By saving a dollar or more per EOB, the cost savings can quickly add up to millions of dollars per month in savings.

If you’re curious about just how much you can save with email EOBs, try our just-released email EOB ROI calculator. You can see how much your company can save with just a 30 percent shift from physical mail

The most significant cost reduction is the money saved on printing and mailing paper EOB statements. Additionally, the cost of administering the delivery of EOB notices is lowered when it’s done electronically. Resending EOBs in the event of their non-delivery also is much easier, faster and cheaper via email.

Compliance Benefits

Because sending an EOB via email requires HIPAA compliance, your communications are encrypted by default, protecting patient privacy and keeping PHI out of the hands of malicious actors, all while reducing the risk of HIPAA compliance violations. The security features built into HIPAA compliant email platforms, such as encryption, access control, and audit logs, help insurers satisfy the requirements of HIPAA’s Privacy and Security Rules in their compliance efforts.

Another considerable benefit of using secure email to send policyholders their EoBs, or, in fact, any communication containing PHI, is that it’s far easier to implement breach notification protocols. HIPAA compliant email delivery platforms provide real-time tracking, so companies can pinpoint email message failures quickly and act accordingly. Similarly, intrusion detection systems and other cybersecurity measures that support email systems enable the faster detection and containment of data breaches.

In stark contrast, physical mail is far more difficult to track. Consequently, security breaches via mail could go unnoticed for days or even weeks. If you’re unaware of a data breach, let alone have not yet contained or mitigated it, you’re unable to inform all affected parties, resulting in further HIPAA violations and a loss of customer trust.

Reduced Carbon Footprint

It’s difficult to highlight the cost benefits of sending EOBs to policyholders by email without recognizing the positive environmental impact, too. Email EOBs cuts down on paper usage, for both the notices themselves and the envelopes they’re mailed in. Then there’s the matter of the electricity and ink involved in printing them, the emissions produced in their delivery, etc. Opting to send EOBs via email reduces all these factors, which enables healthcare organizations to lower their carbon footprint and, where applicable, meet their sustainability obligations.

Now’s the Time to Move to Email EOBs

LuxSci’s HIPAA compliant Secure High Volume Email solution enables healthcare insurers to instantly send EOBs to policyholders securely and at scale, extending into hundreds of thousands and millions of messages a month.

Our HIPAA compliant email delivery platform features:

Dedicated IPs that isolate critical transactional messages, such as EOBs, from other email traffic, allowing our clients to reach deliverability rates of 98% or more.
Real-time tracking for determining the delivery status of EOBs, as well as troubleshooting unsuccessful delivery attempts.
Flexible encryption through LuxSci’s proprietary SecureLine Technology, which automatically adjusts encryption according to the recipient to better ensure the protection of sensitive data, including for EOBs or any sensitive healthcare communication.

Encryption Optional Email Will Fail Audits in 2026 and Beyond

February 24, 2026
Pete Wermter

For years, healthcare organizations have relied on click-to-encrypt email workflows and secure portals as a practical compromise between usability and compliance. Or in some cases, they simply thought most of their emails did not need to be compliant. In regulated industries where data security and privacy are paramount, this approach was still considered “good enough.”

That era is ending.

As we progress into 2026 and beyond, regulators, auditors, and cyber insurers are sending a clear and consistent message: encryption that depends on human choice is no longer acceptable. It’s already happening. Encryption optional email isn’t merely raising concerns, it’s failing audits outright.

An Email Threat Landscape That’s Changing Faster Than Email Habits

Historically, email encryption was treated as a best practice rather than a hard requirement. If an organization could demonstrate that encryption tools existed and that employees had access to them, auditors were often satisfied. The box was checked, everybody moved on.

Today, the questions auditors ask are fundamentally different. Instead of asking whether encryption is available, they are asking whether sensitive data can ever leave the organization unencrypted. If the answer is yes, even in rare cases, or even accidentally, that’s no longer viewed as an acceptable gap. It’s viewed as inadequate control.

Why 2026 Is a Tipping Point for Email Security

Several forces are converging here in 2026 that make optional encryption increasingly untenable. Regulatory scrutiny around PHI and PII exposure continues to intensify. Breach costs and litigation are rising, with email remaining one of the most common vectors for data exposure and breaches. AI is also changing the game for cybercriminals, and attacks will continue to increase and be more sophisticated. As a result, cyber insurers are tightening underwriting requirements and demanding stronger, more predictable controls.

At the same time, email user behavior is unpredictable and inconsistent, which is a non-starter for data security in today’s world.

Taken together, these trends and behaviors point to a single requirement: email security controls must be automated. They must be enforced by systems, not dependent on employee memory, judgment, or good intentions.

The Reality of “Encryption Optional” in Practice

On paper, optional encryption can sound reasonable. In practice, it creates gaps large enough to open you up to a breach.

Secure portals are a good example. They require recipients to click a link, authenticate, and access content in a controlled environment. While this protects data in transit, and is a better approach than no security at all, it also introduces friction. And people don’t like friction. Senders forget to use the portal. Recipients ask for “just a quick email instead.” Shortcuts are taken to save time. And every shortcut becomes a risk.

Click-to-encrypt systems suffer from a similar problem. They rely on users to correctly identify sensitive data and remember to take action. But people often misclassify information, forget to click the button, or assume someone else has already secured the message. From an auditor’s perspective, this isn’t a training failure. It’s a set-up and control failure.

Email Security Defaults Are the New Normal

The latest message from regulators, auditors, and insurers is clear. If encryption is optional, data vulnerabilities become inevitable.

What can you do?

Below is a quick email security checklist to help you get started. Cyber insurers may require or recommend the following safeguards during the underwriting process, such as:

Multi-factor authentication (MFA)
Endpoint protection
Encrypted backups
Incident response planning
Encryption protocols for sensitive data in transit and at rest, including PHI in emails

In 2026 and beyond, healthcare organizations and regulated industries will be judged not by what they allow, but by what they prevent. Automated, encrypted email is the new. normal.

How to Secure SMTP Email Delivery with TLS

August 29, 2023
Erik Kangas

Secure email sending is a priority for organizations that communicate sensitive data externally. One of the most common ways to send secure emails is with SMTP TLS. TLS stands for Transport Layer Security and is the successor of SSL (Secure Socket Layer). TLS is one of the standard ways that computers on the internet transmit information over an encrypted channel. In general, when one computer connects to another computer and uses TLS, the following happens:

Computer A connects to Computer B (no security)
Computer B says “Hello” (no security)
Computer A says, “Let’s talk securely over TLS” (no security)
Computers A and B agree on how to do this (secure)
The rest of the conversation is encrypted (secure)

In particular:

The conversation is encrypted
Computer A can verify the identity of Computer B (by examining its SSL certificate, which is required for this dialog)
The conversation cannot be eavesdropped upon (without Computer A knowing)
A third party cannot modify the conversation
Third parties cannot inject other information into the conversation.

TLS and SSL help make the internet a more secure place. One popular way to use TLS is to secure SMTP to protect the transmission of email messages between servers.

Secure SMTP Email Delivery with TLS

The mechanism and language by which one email server transmits email messages to another email server is called Simple Mail Transport Protocol, or SMTP. For a long time, email servers have had the option of using TLS to transparently encrypt the message transmission from one server to another.

When available, using TLS with SMTP ensures the message contents are secured during transmission between the servers. Unfortunately, not all servers support TLS! Many email providers, especially free or public ones, have historically not supported TLS. Thankfully, the trend is shifting. LuxSci found that most providers now support TLS- approximately 85% of domains tested as of July 2022.

Using TLS requires that the server administrators:

purchase SSL certificates
configure the email servers to use them (and keep these configurations updated)
allocate additional computational resources on the email servers involved.

For TLS transmission to be used, the destination email server must offer support for TLS, and the sending computer or server must be configured to use TLS connections when possible.

The sending computer or server could be configured for:

No TLS: never use it.
Opportunistic TLS: use it if available; if not, send it insecurely.
Forced TLS: use TLS or do not deliver the email at all.

How Secure is Email Delivery over SMTP TLS?

TLS protects the transmission of the email message contents. It does nothing to protect the security of the message before it is sent or after it arrives at its destination. For that, other encryption mechanisms may be used, such as PGP, S/MIME, or storage in a secure portal.

For sending sensitive information to customers, transmission security is the minimum standard for compliance with healthcare and financial regulations. TLS is appropriate to meet most compliance requirements and offers an excellent alternative to more robust and less user-friendly encryption methods (like PGP and S/MIME).

There are different versions of TLS- 1.0 and 1.1 use older ciphers and are not as secure, while TLS 1.2 and 1.3 use newer ciphers and are more secure. When an email is sent, the level of TLS used is as secure as can be negotiated between the sending and receiving servers. If they both support strong encryption (like AES 256), then that will be used. If not, a weaker grade of encryption may be used. The sending and receiving servers can choose the types of encryption they will support. If there is no overlap in what they support, then TLS will fail (this is rare).

What About Replies to Secure Messages?

Let’s say you send a message to someone that is securely delivered to their inbox over TLS. Then, that person replies to you. Will that reply be secure? This may be important if you are communicating sensitive information. The reply will use TLS only if:

The recipient’s servers support TLS for outbound email (there is no way to test this externally).
The mail servers (where the “From” or “Reply” email address is hosted) support TLS for inbound email.
Both servers support overlapping TLS ciphers and protocols and can agree on a mutually acceptable means of encryption.

Unless familiar with the providers in question, it cannot be assumed that replies will use TLS. So, what should you do? Ultimately, it depends on what compliance standards you must meet, the level of risk you are willing to accept, and the types of communications you send. There are two general approaches to this question:

Conservative. If replies must be secure in all cases, assuming TLS will be used is unreasonable. In this case, a more secure method should be used to encrypt the messages in transit and store them upon arrival. The recipient must log in to a secure portal to view the message and reply securely. Alternatively, PGP or S/MIME could be used for additional security.
Aggressive. In some compliance situations like HIPAA, healthcare providers must ensure that ePHI is sent securely to patients. However, patients are not beholden to HIPAA and can send their information insecurely to anyone they want. If the patient’s reply is insecure, that could be okay. For these reasons, and because using TLS for email security is so easy, many do not worry about the security of email replies. However, this should be a risk factor you consider in an internal security audit. Consider nuanced policies that allow you to send less sensitive messages with TLS while sending more sensitive messages with higher security.

What are the Weaknesses of SMTP TLS?

As discussed, SMTP TLS has been around for a long time and has recently seen a great deal of adoption. However, it has some deficiencies compared to other types of email security:

There is no mandatory support for TLS in the email system.
A receiver’s support of the SMTP TLS option can be trivially removed by an active man-in-the-middle because TLS certificates are not actively verified.
Encryption is not used if any aspect of the TLS negotiation is undecipherable/garbled. It is very easy for a man-in-the-middle to inject garbage into the TLS handshake (which is done in clear text) and have the connection downgraded to plain text (opportunistic TLS) or have the connection fail (forced TLS).
Even when SMTP TLS is offered and accepted, the certificate presented during the TLS handshake is usually not checked to see if it is for the expected domain and unexpired. Most MTAs offer self-signed certificates as a pro forma. Thus, in many cases, one has an encrypted channel to an unauthenticated MTA, which can only prevent passive eavesdropping.

The Latest Updates to Secure SMTP TLS

Some solutions help remedy these issues—for example, SMTP Strict Transport Security. SMTP STS enables recipient servers to publish information about their SMTP TLS support in their DNS. This prevents man-in-the-middle downgrades to plain text delivery, ensures more robust TLS protocols are used, and can enable certificate validation.

In addition, users can adopt TLS 1.3. NIST recommends that government agencies develop migration plans to support TLS 1.3 by January 1, 2024. LuxSci supports both SMTP MTA-STS and TLS 1.3.

How Secure SMTP TLS Email Works with LuxSci

Inbound TLS

LuxSci’s inbound email servers support TLS for encrypted inbound email delivery from any sending email provider that also supports that. For selected organizations, LuxSci also locks down its servers to only accept email from them if delivered over TLS.

Outbound Opportunistic TLS

LuxSci’s outbound email servers will always use TLS with any server that claims to support it and with whom we can talk TLS v1.0+ using a strong cipher. The message will not be sent securely if the TLS connection to such a server fails (due to misconfiguration or no security protocols in common). Outbound opportunistic TLS encryption is automatic for all LuxSci customers, even those without SecureLine.

Forced TLS

When Forced TLS is enabled, the message is either dropped or sent with an alternate form of encryption if the recipient’s server does not support TLS. This ensures that messages will never be sent insecurely. Forced TLS is also in place for all LuxSci customers sending to banks and organizations that have requested that we globally enforce TLS to their servers.

Support for strong encryption

LuxSci’s servers will use the strongest encryption supported by the recipient’s email server. LuxSci servers will never employ an encryption cipher that uses less than 128 bits (they will fail to deliver rather than deliver via an excessively weak encryption cipher), and they will never use SSL v2 or SSL v3.

Does LuxSci Have Any Other Special TLS Features?

When using LuxSci SecureLine for outbound email encryption:

SMTP MTA STS: LuxSci’s domains support SMTP MTA STS, and LuxSci’s SecureLine encryption system leverages STS information about recipient domains to improve connection security.
Try TLS: Account administrators can have secure messages “try TLS first” and deliver that way. If TLS is unavailable, the messages would fall back and use more secure options like PGP, S/MIME, or Escrow. Email security is easy, seamless, and automatic when communicating internally or with others who support TLS.
TLS Exclusive: This is a special LuxSci-exclusive TLS sending feature. TLS Exclusive is just like Forced TLS, except that messages that can’t connect over TLS are just dropped. This is ideal for low-importance emails that must still be compliant, like email marketing messages in healthcare. In such cases, the ease of use of TLS is more important than receiving the message.
TLS Only Forwarding: Account administrators can restrict any server-side email forwarding settings in their accounts from allowing forwarding to any email addresses that do not support TLS for email delivery.
Encryption Escalation: Often, TLS is suitable for most messages, but some messages need to be encrypted using something stronger. LuxSci allows users to escalate the encryption from TLS to Escrow with a click (in WebMail) or by entering particular text in the subject line (for messages sent from email programs like Outlook).
Domain Monitoring: When TLS delivery is enabled for SecureLine accounts, messages will never be insecurely sent to domains that purport to be TLS-enabled, i.e., TLS delivery is enforced and no longer “opportunistic.” The system monitors these domains and updates their TLS-compliance status daily.
Double Encryption: Messages sent using SecureLine and PGP or S/MIME will still use Opportunistic TLS whenever possible for message delivery. In these cases, messages are often “double encrypted.” First, they are encrypted with PGP or S/MIME and may be encrypted again during transport using TLS.
No Weak TLS: Unlike many organizations, LuxSci’s TLS support for SMTP and other servers only supports those protocol levels (e.g., TLS v1.0+) and ciphers recommended by NIST for government communications and which are required for HIPAA. So, all communications with LuxSci servers will be over a compliant implementation of TLS.

For customers who can use TLS to meet security or compliance requirements, it enables seamless security and “use of email as usual.” SecureLine with Forced TLS enables clients to take advantage of this level of security whenever possible while automatically falling back to other methods when TLS is unavailable.

Of course, using Forced TLS as the sole method of encryption is optional; if your compliance needs are more substantial, you can turn off TLS-Only delivery or restrict it so that it is used only with specific recipients.

If your email use cases are complicated, LuxSci’s flexibility enables the secure sending of emails to any recipient, regardless of their email service provider’s support for TLS. Contact the LuxSci sales team to learn more about our secure SMTP TLS email sending.

Webinar: How to Harness HIPAA-Compliant Marketing & Workflows

July 24, 2024

In today’s connected world with millions of messages bombarding people every second of the day, personalized engagement over digital channels is a requirement for any business – especially in healthcare. However, ensuring that your marketing efforts comply with the Health Insurance Portability and Accountability Act (HIPAA) can be a daunting task that never quite gives you the peace of mind you need. The good news is that you don’t have to lose sleep at night worrying about whether your marketing campaigns are secure and protected from data breaches and outside threats. With the right strategies and solutions, you can create HIPAA-compliant marketing campaigns that not only keep data protected, but also boost lead conversions, improve outcomes, and reduce costs.

Here are some simple but necessary steps to get you off and running with HIPAA-compliant marketing campaigns today:

Understand HIPAA Requirements

Before embarking on any marketing campaign, it’s crucial to have a thorough understanding of HIPAA regulations. HIPAA sets strict guidelines for keeping protected health information (PHI) safe. Ensure your marketing team is well-versed in these regulations to avoid any compliance failures. If you’re not sure, check out this recent LuxSci blog post on understanding encryption requirements for HIPAA-compliant email.

Leverage Automated Data Encryption

Safeguarding protected health information (PHI) is a requirement with HIPAA. Use advanced encryption methods – including dedicated cloud infrastructures and automation that encrypts every email sent with no user intervention required – to secure patient and customer data both in transit and at rest. This ensures that any data shared during marketing campaigns remains confidential and secure from breaches.

Implement Consent Management

Obtaining explicit consent from patients and customers before using their information in marketing campaigns is a also requirement and non-negotiable. Make sure you have a consent management system that records, stores, and manages patient and customer consent effectively and efficiently.

Personalize and Hypersegment Campaigns Using PHI Data

HIPAA does not need to hold you back. In fact, using PHI data can take your email targeting and messages to the next level. Personalized marketing can significantly improve patient and customer engagement and increase your lead conversions. Use PHI data to tailor your marketing messages to the specific needs and preferences of precise segments to ensure content is relevant and valuable – and actionable.

Utilize Encryption for All Healthcare Communications

Communicating with patients and healthcare customers through secure channels is essential for ALL communications, not just those that require HIPAA compliance. Use flexible encrypted email services, secure messaging apps, and patient portals to share sensitive information, and protect yourself from the latest cybersecurity threats at all times.

Monitor, Analyze and Improve Marketing Campaigns

Regularly test, monitor and analyze your marketing campaigns to ensure ongoing HIPAA compliance and the best results, using data on emails delivered, opened, clicked and secured. Take action in real-time to improve segmentation and results based on your latest business needs and deliverability requirements.

Benefits of HIPAA-Compliant Marketing

Implementing HIPAA-compliant marketing strategies offers numerous benefits, including:

Improved healthcare experiences – Personalized and secure communications build trust and strengthen relationships with patients and customers.

More lead conversions – Hypersegmentation and automation drive higher conversion rates and improve patient and customer engagement.

Increased sales opportunities and revenue – Targeted, timely communications and campaigns drive the best results for growing your business.
