Designed for Compliance and Performance

LuxSci is HIPAA-compliant and HITRUST Certified, ensuring your healthcare communications stay within the bounds of regulatory compliance, keeping patient and company data secure—even as your email sending volume scales into the millions.

Authentication Gets a Major Upgrade

With the latest API release, LuxSci now supports three industry-standard authentication methods—alongside its proprietary LuxSci Secure option.

Let’s break them down:

OAuth 2.0 – The modern standard. Secure, flexible, and ideal for enterprise-scale integrations.
API Key – Simple and efficient. Ideal for server-to-server use when convenience matters most.
Basic Authentication – Straightforward and widely supported. Great for internal systems and quick testing.

Still Available and Highly Recommended: LuxSci Secure Authentication

For those who want the tightest possible control over API sessions—including HMAC signatures and session revocation—LuxSci Secure authentication remains the best option for customers.

Now, let’s take a closer look at how each of the new authentication methods work:

OAuth 2.0: A Standards-Based Approach

OAuth 2.0 gives you a robust framework to handle both account-level and user-level integrations.

Account-Level Authentication (Client Credentials Flow)

Perfect for system-level access—including EHR, CDP or RCM platform integrations where user context isn’t needed.

User-Level Authentication (Resource Owner Password Credentials Flow)

This method allows API access on behalf of individual users—great for patient portals or provider tools.

Security, Flexibility, and Simplicity Combined

Tokens expire after a default of 15 minutes, ensuring sessions aren’t left open indefinitely. Bonus: No message body signing is required, making integration quick and painless.

API Key: Simple and Straightforward

API Key authentication is as easy as including your credentials in a custom header. No session to manage, no extra handshake steps.

How It Works:

You send the HTTP header

X-API-Key: client_id:client_secret

With each request. That’s it.

Ideal Use Cases

Server-to-server automation
Internal dashboards
Data exports from analytics platforms

Basic Authentication: Familiar and Easy

Basic Auth is a time-tested option. Just Base64 encode your API credentials, include them in an HTTP header, and go.

While not as bulletproof as OAuth or LuxSci Secure, API Key and Basic Auth work fine for less sensitive data or development environments.

Easy Access to YAML Specs and SwaggerHub for API Testing

LuxSci has also published detailed YAML API specifications, making it easier for developers and IT teams to access testing interfaces.

You can find more information on our LuxSci API page.

Improved MFA and Easier Access to Testing Tools

As part of today’s announcement, LuxSci also rolled out new, smarter Multi-Factor Authentication (MFA) for enhanced web interface login protection.

LuxSci now ensures that each MFA code can be used only once. So, even if a hacker captures your password and MFA code, they are useless for conducting new login sessions. This update helps protect against automated phishing, spoofing, and fake login pages.

What you’ll learn:

New HIPAA Security Rule Makes Email Encryption Mandatory—Act Now!

April 6, 2026
Pete Wermter

The 2026 Deadline Is Closer Than You Think

The upcoming HIPAA Security Rule overhaul is expected to finalize by mid-2026, and it’s shaping up to be one of the most significant updates in years. Healthcare organizations that fail to prepare, especially when it comes to email security, will face immediate compliance gaps the moment enforcement begins.

Mid-2026 may sound distant, but for healthcare IT and compliance leaders, it’s right around the corner. Regulatory change at this scale doesn’t happen overnight, it requires planning, vendor evaluation, implementation, and internal alignment.

This isn’t a gradual shift. It’s a hard requirement.

Encryption Is About to Become Mandatory

For years, HIPAA has treated encryption as “addressable,” giving organizations flexibility in how they protect sensitive data. That flexibility is disappearing.

Under the updated rule, encryption, particularly for email containing protected health information (PHI), is expected to become a required safeguard.

That means:

Encryption must be automatic and standard for email, not optional
Policies must be enforced consistently
Email security can’t depend on human behavior

If your current system relies on users to manually trigger encryption, it’s already out of step with where compliance is heading. If you’re not encrypting your emails at all, then now is the time to re-evaluate and rest your technology and policies.

Email Is the Weakest Link in Healthcare Security

Email remains the most widely used communication tool in healthcare—and the most common source of data exposure. Every day, sensitive information flows through inboxes, including patient records, lab results, billing details, plan renewals and appointment reminders. Yet many organizations still depend on:

Basic TLS encryption that only works under certain conditions
Manual processes that leave room for human error
Limited visibility into email activity and risk

It only takes one mistake, such as a missed encryption trigger or a misaddressed email, to create a reportable breach. Regulators are well aware of this. That’s why email is a primary focus of the upcoming HIPAA Security Rule changes.

The Cost of Waiting Is Higher Than You Think

Delaying action may feel easier in the short term, but it significantly increases risk. Once the new rule is finalized, organizations without compliant systems may face:

Immediate audit failures
Regulatory penalties
Expensive, rushed remediation efforts
Or worst of all, an email security breach

Beyond financial consequences, there’s also reputational harm. Patients expect their data to be protected. A single incident can immediately erode trust and damage your brand beyond repair.

Waiting until the end of 2026 also means that you’ll be competing with every other organization trying to fix the same problem at the same time, driving up costs and limiting vendor availability.

Most Email Solutions Won’t Meet the New Standard

Here’s the uncomfortable reality: many existing email platforms won’t be enough, especially those that are not HIPAA compliant. Common gaps include:

Encryption that isn’t automatic or policy-driven
Lack of Data Loss Prevention (DLP)
Insufficient audit logging for compliance reporting
Lack of Zero Trust security principles

On top of that, vendors without alignment to HITRUST certification and Zero-Trust architectures may struggle to demonstrate the level of assurance regulators will expect moving forward.

If your current solution wasn’t designed specifically for healthcare and HIPAA compliance, it’s likely not ready for what’s coming.

LuxSci Secure Email: Built for What’s Next

This is where a purpose-built solution makes all the difference. LuxSci HIPAA compliant email is designed specifically for healthcare organizations navigating the latest compliance requirements, not just today, but in the future regulatory landscape.

LuxSci delivers:

Automatic, policy-based encryption that removes user guesswork
Advanced DLP controls to prevent PHI exposure before it happens
Comprehensive audit logs to support audits and investigations
Zero Trust architecture that verifies every user and action

Additionally, LuxSci is HITRUST-certified, helping organizations demonstrate a mature and defensible security posture as regulations tighten. Email data protection isn’t about patching gaps, it’s about eliminating them.

Act Now or Pay Later

If there’s one takeaway, it’s this: the time to act is now. Start by asking a few direct questions:

Is our email encryption automatic and enforced?
Do we have full visibility into email activity and risk?
Is our vendor equipped for evolving HIPAA requirements?

If the answer to any of these is unclear, now’s the time to take action. Organizations that move early will have time to implement the right solution, train their teams, and validate compliance. Those that wait will be forced into reactive decisions under pressure.

Conclusion: The Time to Act is Now!

The HIPAA Security Rule overhaul is coming fast, and it’s raising expectations across the board. Encryption will no longer be addressable, but rather mandatory. As a result, email security can no longer be overlooked, and compliance will no longer tolerate gaps.

LuxSci HIPAA compliant email provides a clear, future-ready path for your organization, combining automated encryption, DLP, auditability, and Zero Trust security in one solution.

The real question isn’t whether change is coming. It’s whether your organization will be ready when it does.

FAQs

1. When will the updated HIPAA Security Rule take effect?
The changes to the HIPAA Security Rule are expected to be finalized and announced around mid-2026, with enforcement likely soon after, by the end of the year.

2. Will email encryption truly be mandatory?
Yes, current direction strongly indicates encryption will become a required safeguard, which could start later this year or in early 2027.

3. Is TLS encryption enough for compliance?
No. TLS alone does not provide sufficient, guaranteed protection for PHI.

4. Why is HITRUST important in this context?
HITRUST certification demonstrates a vendor’s strong alignment with healthcare security standards and will likely carry more weight with regulators.

5. How does LuxSci help organizations prepare?
HITRUST-certified LuxSci offers secure email with automated encryption, DLP, audit logs, and Zero Trust architecture, helping organizations meet evolving compliance demands.

Traditional MFA No Longer Qualifies as “Reasonable” Security

March 17, 2026
Pete Wermter

For years, multi-factor authentication (MFA) was considered one of the most effective ways to protect sensitive systems. By requiring a second verification step, such as a text message code or push notification, organizations could significantly reduce the risk of compromised passwords.

But the threat landscape has changed.

Today, attackers routinely bypass traditional MFA using techniques such as MFA evasion, token replay attacks, and consent phishing. These methods are no longer rare or highly sophisticated. They are widely used, automated, and increasingly effective.

As a result, regulators, auditors, and security frameworks are raising expectations for authentication security. For healthcare organizations in particular, traditional MFA alone may no longer satisfy the HIPAA requirement to implement “reasonable and appropriate safeguards.”

In the near future, email systems that rely only on basic MFA, without conditional access or phishing-resistant authentication, may increasingly be viewed as security gaps during risk assessments.

Why Traditional MFA Is No Longer Enough

Traditional MFA still improves security compared to passwords alone. However, many common MFA methods were designed before today’s phishing techniques and cloud authentication attacks became widespread.

Common MFA methods include:

SMS verification codes
Email-based authentication codes
Push notifications to mobile apps

While these mechanisms add friction for attackers, they can still be intercepted or manipulated during sophisticated phishing attacks. Because modern attackers now target authentication workflows directly, organizations relying solely on traditional MFA may be more vulnerable than they realize.

How Attackers Bypass MFA Today

Cybercriminals increasingly rely on tools that capture credentials and authentication tokens during login sessions. Three attack techniques are now especially common.

MFA Evasion and Phishing Proxies – Attackers frequently deploy adversary-in-the-middle phishing kits that sit between the user and the real login service. When users enter their credentials and MFA code on a phishing page, the attacker forwards the information to the legitimate site and captures the authentication session. The user successfully logs in—but the attacker gains access as well. If attackers capture those tokens, they can reuse them to access the account directly.
Token Replay Attacks – After successful authentication, systems typically issue session tokens that allow users to remain logged in without repeated MFA prompts. This technique has been widely observed in attacks targeting cloud email platforms such as Microsoft 365, allowing attackers to access email data even when MFA is enabled.
Consent Phishing – Consent phishing bypasses MFA entirely. Instead of stealing passwords, attackers trick users into granting permissions to malicious applications that request access to their mailbox or files. If users approve the request, the attacker’s application receives persistent access to the account through APIs—often without triggering security alerts.

Why Email Authentication Matters Most in Healthcare

Email remains one of the most critical systems in healthcare organizations. It supports patient communication, internal collaboration, and the exchange of sensitive information. Unfortunately, it is also the most frequently targeted entry point for cyberattacks.

Once attackers gain access to an email account, they can:

Impersonate healthcare staff
Launch internal phishing attacks
Access sensitive patient communications
Extract protected health information (PHI)

Because of this, email authentication controls are becoming a major focus for security teams and compliance auditors alike.

Evolving Regulatory Expectations

HIPAA does not prescribe specific technologies, but it requires organizations to implement safeguards that are “reasonable and appropriate” based on risk. As new attack methods emerge, the definition of reasonable security evolves.

Today, many security frameworks and regulatory bodies are emphasizing stronger identity protections, including:

Phishing-resistant authentication
Conditional access policies
Monitoring for suspicious login behavior
Controls for third-party application permissions

Organizations that rely solely on basic MFA may increasingly struggle to demonstrate that their authentication protections are sufficient.

The Shift Toward Phishing-Resistant Authentication

To address the weaknesses of traditional MFA, many organizations are adopting phishing-resistant authentication technologies, which can be enabled with tools like Duo and Okta. These solutions rely on cryptographic authentication tied to trusted devices, which prevents attackers from capturing or replaying login credentials.

Examples include:

Hardware security keys
Passkeys
Certificate-based authentication

Because authentication is tied to both the device and the legitimate website domain, these technologies significantly reduce the success rate of phishing attacks.

Why Conditional Access Is Becoming Essential

Conditional access adds another layer of protection by evaluating context and risk before granting access. Instead of treating every login the same, conditional access policies analyze signals such as:

Device security status
Geographic location
Network reputation
User behavior patterns

If something appears unusual, such as a login from a new country, the system can require stronger authentication or block the attempt altogether. This risk-based approach to authentication helps prevent many account compromise scenarios.

The Future of HIPAA Risk Assessments

As authentication threats evolve, healthcare security assessments are increasingly focusing on identity protection maturity. Organizations may begin seeing findings related to:

Weak or outdated MFA methods
Lack of conditional access policies
Insufficient monitoring of login activity
Unrestricted third-party application permissions

In particular, email systems without advanced authentication protections may be flagged as high-risk vulnerabilities, especially when PHI is accessible.

LuxSci’s Modern Approach to MFA

Modern threats require more than a simple second login factor. LuxSci approaches authentication security with layered identity protection designed specifically for healthcare environments.

Instead of relying solely on basic MFA methods like SMS codes or email verification, LuxSci supports stronger authentication controls and policies that align with evolving security expectations. These protections can include:

Strong multi-factor authentication options
Monitoring for unusual login behavior
Enhanced identity verification mechanisms

By combining multiple security layers within its HIPAA-compliant secure communications email and marketing solutions, LuxSci helps healthcare organizations protect sensitive email communications while maintaining usability for providers, health plan administrators, payment providers, and patient engagement teams.

Conclusion

Multi-factor authentication remains an important security control—but not all MFA is created equal. Attack techniques such as phishing proxies, token replay, and consent phishing have demonstrated that traditional MFA methods can be bypassed. As a result, regulators and auditors are increasingly expecting stronger identity protections.

For healthcare organizations that rely heavily on email communications, the implications are significant. Weak authentication controls can expose sensitive patient data and may soon appear as high-risk findings during HIPAA risk assessments. The organizations best positioned for the future will be those that modernize authentication strategies now, moving toward phishing-resistant methods, conditional access policies, and layered identity protection.

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.

What Are the Best HIPAA Compliant Email Providers for Healthcare Organizations?

September 30, 2025
Erik Kangas

The best HIPAA compliant email providers deliver strong encryption, complete business associate agreements, reliable audit logging, and efficient integration with healthcare systems while maintaining competitive pricing and responsive customer support. Healthcare organizations evaluating secure email solutions need providers that understand healthcare workflows, offer proven security certifications, and demonstrate consistent compliance with federal privacy regulations. Selecting from the best HIPAA compliant email providers requires examining their track record with healthcare clients, security infrastructure, integration capabilities, and ability to scale alongside organizational growth.

Encryption Standards That Protect Patient Communications

End-to-end encryption transforms healthcare messages into unreadable code that only intended recipients can decrypt, creating a protected communication channel between providers and patients. Advanced Encryption Standard 256-bit encryption converts patient information before transmission across public internet networks, ensuring that intercepted messages cannot reveal sensitive health data. Transport Layer Security protocols establish secure connections between email servers during message delivery, preventing unauthorized access while communications travel between systems.

Authentication requirements verify user identities through multi-factor systems combining passwords with mobile verification codes, biometric scans, or hardware tokens. These layered approaches prevent unauthorized account access even when passwords are compromised through data breaches or phishing attacks. Automatic encryption activation eliminates dependence on manual security features that busy healthcare staff might forget to enable during patient care activities.

Digital signatures provide mathematical verification that messages originated from legitimate healthcare sources and were not altered during transmission. Certificate-based authentication confirms sender identity before allowing message delivery, preventing misdirected emails containing patient information from reaching unintended recipients. Key management protocols protect encryption keys while enabling authorized users to access necessary patient communications without operational delays.

BAAs and Legal Protections

Contracts between healthcare organizations and email providers establish clear responsibilities for protecting patient information and responding to security incidents when they occur. Written agreements specify encryption requirements, data retention policies, incident reporting timelines, and procedures for handling patient information when business relationships terminate. Liability allocation clauses define financial responsibilities when security breaches result from provider negligence or system failures.

SOC 2 Type II certifications demonstrate that providers maintain effective security controls consistently over time rather than just during initial assessments. Independent auditors verify that security measures function properly and meet industry standards for protecting customer data. HITRUST certification indicates provider familiarity with healthcare-specific security requirements and experience serving healthcare organizations.

Insurance verification ensures that providers maintain adequate cyber liability coverage to protect healthcare organizations during security incidents. Coverage should specifically address HIPAA-related claims and regulatory penalties that might result from email security failures. The best HIPAA compliant email providers carry sufficient insurance to cover potential damages without placing healthcare organizations at financial risk. The best HIPAA compliant email providers carry sufficient insurance to cover potential damages without placing healthcare organizations at financial risk.

Audit rights enable healthcare organizations to verify provider compliance with contract terms through access to security reports, penetration testing results, and compliance documentation. These contractual provisions allow organizations to demonstrate due diligence during regulatory inspections. Regular vendor assessments help identify potential security gaps before they create compliance problems.

Healthcare System Integration

Electronic health record connections enable automatic documentation of patient communications within clinical systems without requiring manual data entry from busy healthcare staff. API connectivity allows seamless information exchange between email platforms and practice management software, billing systems, and scheduling applications. Patient communications populate appropriate sections of medical records immediately, supporting clinical decisions with complete information about patient interactions.

Mobile device compatibility enables physicians and staff to access secure communications from smartphones and tablets while maintaining encryption and authentication standards. Native applications provide the same security features as desktop platforms while offering convenient access for providers working from multiple locations throughout their day. Device flexibility ensures that healthcare teams can respond to patient communications quickly regardless of their physical location.

Patient portal connections create unified platforms where individuals can receive test results, ask questions, and access educational materials through consistent interfaces. Integration reduces the number of separate systems that healthcare organizations must maintain and support. Healthcare organizations evaluating the best HIPAA compliant email providers should prioritize single sign-on capabilities that streamline access across connected applications for both providers and patients.

Workflow automation handles routine communications like appointment confirmations and prescription refill notifications without requiring staff intervention. Customizable automation rules adapt to different practice workflows and specialty requirements. The best HIPAA compliant email providers offer automation flexibility that accommodates diverse operational needs without extensive programming.

Cost Structures for the Best HIPAA Compliant Email Providers

Per-user pricing allows healthcare organizations to align email expenses with workforce size while maintaining predictable monthly costs. Volume discounts reduce per-user fees for larger organizations, making secure email more affordable for health systems employing hundreds or thousands of staff members. Pricing tier evaluation helps identify optimal user count thresholds that minimize costs while accommodating growth.

Storage policies determine long-term expenses for organizations that must retain email communications to satisfy regulatory and legal requirements. Unlimited storage eliminates concerns about capacity limits and overage charges, while metered plans may offer lower initial costs but create budget uncertainty. Organizations should calculate storage requirements based on historical communication volumes and mandatory retention periods.

Implementation expenses include data migration assistance, system configuration, and staff training that enable successful deployment. Professional services fees vary based on archive volume, customization needs, and integration complexity. Budget planning for the best HIPAA compliant email providers should account for both recurring subscription costs and one-time implementation charges across anticipated contract durations.

Support packages range from basic assistance included in standard pricing to premium options offering faster response times and dedicated support personnel. Organizations requiring rapid issue resolution for patient care situations may justify premium support costs. Emergency support provides priority assistance during system outages that threaten communication capabilities.

Vendor Evaluation and Due Diligence

Financial stability assessments reveal whether potential providers can sustain service quality throughout multi-year contracts. Provider funding sources, growth patterns, and market position indicate their capacity to invest in security improvements and feature development. Organizations benefit from choosing established providers with proven staying power rather than startups that might not survive market changes.

Customer support quality directly impacts how quickly healthcare organizations can resolve email issues that affect patient care. Support teams familiar with healthcare workflows provide better assistance than generic technical support. Response time guarantees ensure that urgent issues receive prompt attention when communications are disrupted.

Implementation quality determines transition smoothness when moving from existing email systems to new platforms. Migration specialists should understand healthcare data sensitivity and compliance requirements during archive transfers. Configuration expertise helps optimize security settings and workflow integrations without disrupting operations.

Security update procedures maintain current protection standards without requiring manual intervention from healthcare IT teams. Automated updates apply security patches while preserving system availability during patient care hours. Maintenance schedules should align with healthcare operation patterns to minimize disruption.

Selection Process and Decision Framework

Security evaluations examine encryption strength, authentication methods, access controls, and audit capabilities that providers implement for healthcare clients. Penetration testing results and vulnerability assessments provide objective evidence of security effectiveness. Healthcare organizations need verification that provider security measures exceed minimum regulatory requirements.

Pilot testing with limited user groups identifies potential workflow issues before organization-wide deployment. Real-world usage scenarios reveal how email platforms perform under actual clinical conditions with typical message volumes. User feedback during pilots helps refine configurations before full implementation.

Reference conversations with current healthcare customers provide insights into provider performance that sales demonstrations cannot reveal. Organizations of similar size and complexity share experiences about support quality, security incidents, and compliance assistance. The best HIPAA compliant email providers maintain satisfied customers willing to discuss their partnerships openly and provide honest assessments of provider strengths and limitations.

What Should a HIPAA Email Retention Policy Include?

April 21, 2025
Erik Kangas

A HIPAA email retention policy should include classification procedures for different email types, retention schedules based on content and legal requirements, secure storage and disposal methods, access controls for archived communications, and compliance monitoring procedures. The policy must address both HIPAA documentation requirements and broader legal obligations while providing clear guidance for staff implementation and ongoing management. Healthcare organizations need comprehensive retention policies that address complex regulatory landscapes without creating unnecessary administrative burden. Well-designed policies help ensure compliance while managing storage costs and supporting operational efficiency across the organization.

Email Classification and Categorization Guidelines

Content-based categories help staff identify appropriate retention periods by distinguishing between patient care communications, administrative messages, and marketing materials. Each category should have clear examples and decision criteria to ensure consistent application. PHI identification procedures enable staff to recognize when email communications contain protected health information requiring special handling and extended retention periods. These procedures should address obvious PHI like patient names as well as indirect identifiers that could reveal patient information. Business purpose classification distinguishes between emails supporting patient treatment, healthcare operations, payment activities, and other organizational functions. Different business purposes may trigger different retention requirements under various regulatory programs.

Retention Schedule Specifications

Minimum retention periods should reflect the longest applicable requirement from HIPAA email retention policy, state medical record laws, federal programs, and organizational needs. The policy should clearly state these periods for each email category and explain the basis for each requirement. Maximum retention limits help organizations manage storage costs and reduce litigation exposure by establishing when emails should be destroyed unless legal holds or other special circumstances require continued preservation. These limits should balance compliance needs with practical considerations. Exception procedures provide guidance for situations requiring deviation from standard retention schedules such as litigation holds, ongoing investigations, or patient access requests. These procedures should specify approval processes and documentation requirements for exceptions.

Storage and Archive Management Requirements

Security standards for archived emails must maintain the same level of PHI protection as active communications throughout the retention period. The policy should specify encryption requirements, access controls, and monitoring procedures for archived communications. Storage location specifications define where different types of email communications should be preserved including on-premises systems, cloud services, or hybrid approaches. These specifications should address data sovereignty, vendor requirements, and disaster recovery needs. Migration procedures ensure that archived emails remain accessible as technology systems change over time. The policy should address format preservation, system upgrades, and vendor transitions that could affect archived email accessibility.

Access Control and Retrieval Procedures

Authorization requirements define who can access archived email communications and under what circumstances. The policy should establish role-based permissions that limit access to personnel with legitimate business needs while maintaining audit trails. Search and retrieval protocols provide step-by-step procedures for locating archived emails during audits, legal discovery, or patient access requests. These protocols should specify search parameters, documentation requirements, and quality control measures. Emergency access procedures enable retrieval of archived communications during urgent situations when normal approval processes might delay patient care. These procedures should include alternative authorization methods and enhanced audit requirements.

Disposal and Destruction Standards

Secure deletion methods ensure that email content and metadata are completely removed when retention periods expire. The policy should specify approved destruction techniques that prevent unauthorized recovery of PHI from disposed communications. Certification requirements mandate documentation of email destruction activities including dates, methods used, and personnel responsible. These certifications support compliance demonstrations and help track disposal activities across the organization. Media destruction procedures address proper disposal of storage devices containing archived emails when equipment reaches end of life. A HIPAA email retention policy should specify physical destruction or certified wiping procedures that prevent PHI recovery.

Compliance Monitoring and Audit Support

Review schedules establish regular assessment of email retention practices to ensure continued compliance with policy requirements and changing regulations. These reviews should evaluate policy effectiveness, system performance, and staff compliance. Audit preparation procedures provide guidance for responding to regulatory reviews or legal discovery requests involving archived email communications. These procedures should include search protocols, production formats, and timeline management. Performance tracking helps organizations measure their success in meeting retention obligations while identifying areas needing improvement. Key metrics might include retention compliance rates, retrieval response times, and storage cost management.

Staff Training and Implementation Guidance

Training requirements specify education that personnel must receive about email retention obligations and their role in policy implementation. Training should cover classification procedures, retention schedules, and proper handling of archived communications. Implementation timelines provide realistic schedules for deploying new retention policies while allowing adequate time for staff training, system configuration, and process development. These timelines should consider organizational capacity and change management needs. Resource allocation addresses personnel, technology, and financial requirements for effective email retention policy implementation. The policy should specify roles and responsibilities while identifying budget needs for ongoing operations.

Legal and Regulatory Compliance Integration

Regulatory coordination ensures that a HIPAA email retention policy is adhered to, aligning with requirements from state laws, federal programs, and professional licensing boards. The policy should identify all applicable requirements and explain how conflicts are resolved. Legal hold procedures provide immediate preservation capabilities when litigation is anticipated or pending. These procedures should include notification processes, scope determination, and coordination with legal counsel to ensure comprehensive preservation. Update mechanisms ensure that retention policies remain current as regulations change or organizational needs evolve. A HIPAA email retention policy should specify review frequencies, approval processes, and communication procedures for policy modifications.

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.

What is a Secure Email Gateway?

October 24, 2023
LuxSci

As threats to email security are increasing, organizations are looking for ways to enhance their security and reduce risk. One option is a secure email gateway. In this article, we review what secure email gateways are and how they can be used to secure sensitive data as it flows into and out of your accounts.

Protect Your Accounts With A Secure Email Gateway

Secure email gateways are an excellent way to strengthen the security of your email accounts without a costly switch to a new email provider. They layer on top of your existing email accounts to encrypt messages, scan for threats, and even capture messages for archival or backup purposes. They can also hide the sender’s IP address because messages are routed through another email infrastructure before delivery to the recipient. If you are concerned about increasing risks to sensitive data, secure email gateways offer a simple and effective way to enhance your email security.

How Do Secure Email Gateways Work?

When using a secure email gateway, your messages are routed to a separate server before being sent or received. When sending an outbound message with LuxSci’s Secure Connector, it is routed through our SecureLine encryption before being securely delivered to the recipient. A copy of the message may also be sent to an independent email archive to help meet compliance requirements for message retention.

For incoming messages, the gateway can employ email filtering technology to quarantine suspicious messages. These technologies can scan incoming messages and prevent spammers and scammers from reaching employee inboxes and wreaking havoc. Just like with outbound email sending, the gateway can also capture a copy of inbound messages and retain them in an independent message archive.

The exact features of a secure email gateway will vary from vendor to vendor, but these represent some of the core functions that these tools provide. Simply put, a secure email gateway protects both incoming and outgoing messages to ensure that sensitive data is guarded from threats.

Why Choose a Secure Gateway?

There are two main reasons to implement a secure email gateway: the security and compliance benefits and their ease of use. Let’s look at each.

Compliance and Security Benefits

Many companies, like healthcare organizations, must comply with regulations for protecting patient or customer data. Many organizations grapple with the best way to secure potentially sensitive communications without interfering with or slowing down critical business workflows. Because secure email gateways layer on top of existing email accounts, they offer a speedy way to bring your organization into compliance with data security and retention guidelines.

As email continues to be an important channel for essential business communications, all organizations can benefit from protecting their employee accounts and reducing their risk and liability.

Easy to Administer and Use

Another benefit of using a secure email gateway is that your organization does not need to switch your primary email provider to enhance its security. Changing to a more secure email provider can be extremely challenging, especially if you have a lot of users with a lot of data that needs to be migrated to a new system. Add on the training time, and some organizations will find that switching email providers is a significant burden on the organization.

Installing a secure email gateway is very easy for account administrators and often does not require additional training or implementation for email users. Employees can continue to use their regular Microsoft or Google email accounts and do not need to take additional steps to learn an entirely new email program. With 73% of breaches in the healthcare industry caused by human factors, implementing tools that don’t rely on employee decision-making is essential.
