September 26, 2024

Maintaining HIPAA compliance is a critical requirement for healthcare providers, payers and suppliers dealing with protected health information (PHI). Ensuring your email communications align with those standards can be, well… tricky. With fines reaching into the millions, non-compliance isn’t something you want to risk. We’ve seen it time and time again when engaging with our customers and prospects. Unfortunately, many organizations fall into the trap of believing they’re sending HIPAA compliant emails because they’ve applied what we call “self-certification” strategies—without fully understanding what’s required to be compliant.

Are you 100% sure that you’re sending HIPAA compliant emails?

In this blog post, we’ll delve into the risks of being non-compliant, explain why self-certification strategies often lead to problems, and provide a HIPAA-compliant email checklist to help ensure your organization avoids the pitfalls self-compliance.

The Importance of Sending HIPAA Compliant Emails

HIPAA (Health Insurance Portability and Accountability Act) was established to ensure the protection and privacy of patients’ PHI. This law mandates that any entity handling PHI must implement strict safeguards to prevent unauthorized access, breaches, and exposure of sensitive patient data.

In today’s digital world, where healthcare communications often take place over email and other digital platforms, maintaining HIPAA compliance becomes even more complex. It’s not enough to merely think you’re compliant; you must be able to prove it beyond a doubt.

What Is PHI and Why Does It Need to Be Protected?

As a quick reminder, PHI refers to any data that can be used to identify an individual and that relates to their past, present, or future health condition. This can include anything from personal identification information to medical records and billing information to email exchanges that reference patient care.

Examples of PHI include:

Names
Addresses
Birth dates
Social Security numbers
Medical history and diagnoses
Treatment plans & prescriptions
Medical device usage and services
Appointment information
Billing, payments and insurance information

The Risks of Not Being 100% Sure About HIPAA Compliance

In addition to losing sleep at night, the consequences of sending non-compliant emails can be significant. Non-compliance can result in hefty penalties, ranging from $100 to $50,000 per violation, depending on the severity and intent. In some cases, these fines can even surpass $1.5 million annually.

But it’s not just the fines—PHI exposure opens the door to a variety of serious risks, including the reputational damage that can stem from breaches of patient data that can impact peoples’ lives and the future of your business. Patients place immense trust in healthcare providers and organizations to safeguard their sensitive information, which stretches beyond HIPAA-compliance to overall data security and privacy. The loss of patient trust is difficult—if not impossible—to regain once compromised.

The Problem with DIY HIPAA Compliance

Simply put, self-certifying HIPAA compliance is a recipe for disaster. Many companies and healthcare organizations falsely believe that if they conduct an internal review or have implemented basic security measures, they’re fully compliant. But without the right expertise and the right technology in place, especially encryption, it’s easy to overlook crucial details.

Even if you have encryption in place or think your emails are safe, these minimal steps can create a false sense of security. True HIPAA compliance requires continuous monitoring, updating of policies, and regular training to address potential risks.

A Checklist for Sending HIPAA Compliant Email

Sending HIPAA compliant email means ensuring you’ve implemented the following safeguards:

1. Encryption Standards for HIPAA Compliance

All emails containing PHI must be encrypted both at rest and in transit—end-to-end. Ensure your email service provider offers high-grade encryption protocols, like TLS (Transport Layer Security), for sending and receiving messages, and flexible options, including dedicated cloud infrastuctures for the highest levels of data protection.

2. Secure Access and Authentication

Set up multi-factor authentication (MFA) and role-based access controls to limit who can access emails containing PHI.

3. Business Associate Agreements (BAA)

If you’re using a third-party email provider, you must have a signed BAA. This agreement ensures that the provider will uphold HIPAA’s security standards.

4. Data Backup and Recovery

Make sure your email system has a secure backup and recovery solution. Data breaches can happen, but having a recovery plan will minimize damage and maintain compliance.

5. Employee Training and Awareness

Ensure your employees are regularly trained on HIPAA guidelines. Human error is one of the leading causes of HIPAA violations, so proper education is key.

6. Regularly Audit Your HIPAA Compliance Strategy & Practices

HIPAA regulations evolve as technology advances. Conducting regular compliance audits ensures your security protocols are up to date with the latest best practices.

7. Avoiding Overconfidence in Your Own Processes

No matter how confident you are in your HIPAA strategy, bringing in an external auditor can provide an unbiased view of your compliance status and help identify overlooked vulnerabilities.

Don’t Let HIPAA Self-Certification Fool You!

HIPAA compliance is not something you can afford to be unsure about. The risks—both financially and reputationally—are too great. While it may be tempting to “self-certify” or assume your current measures are sufficient, doing so can leave your organization—and your patients and customers—vulnerable. Instead, ensure that you follow a comprehensive strategy that includes best-in-class email encryption, secure access, regular audits, employee training, and support from external experts.

Don’t take shortcuts when it comes to protecting sensitive health information and ensuring HIPAA compliance—get it right from the start.

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.

Reach out to LuxSci today to learn how HIPAA compliant email can support both your organization’s engagement and cybersecurity needs.

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.

Traditional MFA No Longer Qualifies as “Reasonable” Security

March 17, 2026

Is SendGrid HIPAA-Compliant?

January 23, 2025
LuxSci

Twilio’s SendGrid is a cloud-based email marketing platform that contains the tools and resources that organizations need to carry out bulk email marketing campaigns. By providing companies with a robust, scalable email infrastructure, SendGrid reduces the technical and management overhead from delivering emails at scale.

SendGrid’s capabilities and benefits are undeniable – and are the reason why the popular platform is the email delivery service of choice for prominent companies like Spotify and Airbnb. For healthcare organizations, however, while reliability and scalability are essential for large-scale patient engagement campaigns and communications, security is another crucial concern. More specifically, for a healthcare company to send electronic protected health information (ePHI) through an email services platform, the service must be HIPAA-compliant.

This then begs the question, is SendGrid a HIPAA compliant email service? Subsequently, can companies use SendGrid to transmit ePHI?

The short answer is no, they are not. Let’s take a closer look…

Is SendGrid HIPAA-Compliant?

SendGrid is not a HIPAA-compliant email service. There are two key reasons for this:

It lacks sufficient encryption measures
SendGrid does not sign business associate agreements (BAAs)

Let’s discuss each reason in greater detail.

Basic Encryption

SendGrid only offers the basic encryption provided by the Simple Mail Transmission Protocol (SMTP), i.e., the standard mechanism used to transmit emails.

Unfortunately, this level of encryption leaves ePHI vulnerable to cyber threats such as business email compromise (BEC) attacks, ransomware, and device loss or theft. In contrast, for an email services platform to be HIPPA-compliant, it must protect ePHI in transit and at rest, using security measures like Transport Layer Security (TLS) encryption and end-to-end encryption.

Refreshingly, SendGrid is clear and upfront about this (in contrast to, Mailchimp, for example, who make you dig a little deeper to determine their non-compliance) – as Twilio’s documentation explicitly says that they do not offer HIPAA-compliant data transmission. Stating, “SendGrid does not natively support HIPAA-compliant data transmission. We do not offer any encryption or security measures surrounding message transmission beyond those included in the SMTP RFC, which was not designed with HIPAA compliancy in mind.”

In short, SendGrid wasn’t designed to withstand the increased cyber risk that accompanies handling ePHI and isn’t HIPPA-compliant as a result.

No Business Associate Agreement

Additionally, in addition to lower levels of encryption, SendGrid does not sign the business associate agreements (BAA) required to be HIPPA-compliant.

A business associate agreement (BAA) is a written contract between a covered entity (your company) and a business associate (a service provider, such as an email services or email marketing platform) that’s an essential requirement of HIPAA compliance. A BAA details how two organizations can share data and the legal responsibilities of each party.

This is again stated on Twilio’s website that says, “Twilio SendGrid does not intend uses of the Service to create obligations under The Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), the Gramm-Leach-Bliley Act (“GLBA”) or similar laws and makes no representations that the Service satisfies the requirements of such laws. If You are (or become) a Covered Entity or Business Associate (as defined in HIPAA) or a Financial Institution (as defined in GLBA), You agree not to use the Service for any purpose or in any manner involving Protected Health Information (as defined in HIPAA) or Nonpublic Personal Information (as defined in GLBA).”

Here, Twilio is explicitly telling you that SendGrid does not fit the requirements of HIPPA-compliant and that you should not use their service to transmit ePHI.

HIPAA-Compliant Alternatives to SendGrid

While healthcare companies cannot rely on popular options like SendGrid if they want to utilize ePHI in their patient outreach campaigns, fortunately, there are HIPAA-compliant email platforms that are specifically designed for organizations that have to comply with the regulations.

As the most experienced HIPAA-compliant email provider, LuxSci specializes in providing secure and scalable HIPAA-compliant services for companies aiming to send hundreds of thousands – or millions – of emails. In light of this, we place security, regulatory and practical considerations front and center when building our solutions – from their early planning stages until final deployment.

Our approach results in tailor-made tools and services like HIPAA-compliant bulk email, secure text and secure marketing. This includes flexible encryption functionality, such as TLS, end-to-end, or role-based access encryption, that enable healthcare organizations to align their security with the sensitivity of the transmitted and their specific business requirements – all while remaining HIPAA compliant.

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.
