Creating secure web forms starts with creating a secure website. This process is more complex than creating web pages and adding an SSL Certificate. A certificate is a solid first step, but it only goes so far as to protect whatever sensitive data necessitates security in the first place.

Naive attempts at security can ultimately make the data less secure and more likely to be compromised by creating an appetizing target for the unscrupulous.

So, what do you do beyond hiring a developer with significant security expertise? Start with this article. Its purpose is to shed light on many of the most significant factors in creating secure web forms and how to address them. At a minimum, reading this article will help you intelligently discuss website security with the developers you hire.

What Is Involved In Creating Secure Web Forms?

If you want to add a secure web form to your website, first, you must understand how to securely configure the website. Website security is a serious and complex topic; this article only discusses the high points. Check out some of our other articles and eBooks for more detailed information on website security.

Here are some of the critical issues that need to be considered:

SSL – Is the website and form secured to transmit data from the end user safely? Is your website form page protected with SSL to prevent tampering with its contents?
Web page content – Is the HTML content sent to the end-user protected from Cross-Site Scripting (XSS) issues, and does it avoid loading objects insecurely or from third parties?
Script Security – Are the scripts or programs that process the submitted data written with security in mind? Do they have any vulnerabilities?
Infrastructure – Is the website hosting provider trusted and known for good security? Are you on a shared server when you should be on a dedicated one?
Data Flows – What do you do with the data once submitted? Is that data secured?
Tracking – Do you track events such as data access and submission?
Archival and Backup – Are there processes to make backups and permanent archives of important data?

SSL – Web Security Starts Here

SSL certificates are required for creating a secure website and form. The SSL certificate allows:

The encryption of data sent to and from your web server and users to prevent eavesdropping or tampering.
Your users trust that they are connecting to your website securely.

An SSL certificates on a properly configured web server encrypts your website data as it flows to and from your end users.

To get an SSL certificate, you can order one directly from a third party, or your web hosting provider will handle it for you. In either case, the web host will need to install the certificate on the server where the website is hosted, and then you will need to make changes to your site to take full advantage of the secure channel you have added.

SSL and Encryption

The most significant reason people use SSL is to encrypt the data transmitted from their website and the end-user. When an end-user visits a page protected by SSL, their web browser communicates over a secure channel with the web server so that all data transmitted is sent over this encrypted channel. This helps prevent eavesdropping and man-in-the-middle attacks on the data (more on these below).

Without SSL encryption, there is little or no protection of the data.

SSL and Trust

The most overlooked and misunderstood aspect of SSL is the establishment of trust. That is, enabling your end-users to trust and feel confident that they are connecting to your website. What else could they be connecting to, you may ask?

Someone with access to the network between the end-user and website could be trying to intercept and read all the web traffic or altering your website pages themselves (e.g., changing your forms to submit the data to them instead of you). This is called a man-in-the-middle attack. Even with SSL security, a man-in-the-middle can present the end-user with an SSL Certificate for your domain name that looks legitimate, like a forged ID card.
The user could be visiting another website that is pretending to be yours. This phishing website could collect information from your users for malicious purposes. Unless your users identify this site as illegitimate, they could be duped into revealing personal information. How could they end up at a phishing website like this? This can happen by clicking on a link emailed to them or by visiting a misspelled version of your URL. No site is immune from such attacks, but you can work to mitigate them.

SSL Certificates and Cybersecurity

As mentioned above, SSL certificates are not the sole website and form security solution, but they can help! To understand how it’s worth looking at how certificates are awarded. SSL certificates are signed by a third-party authority, the “Certificate Authority.” This can be:

You, if you sign your certificates.
A respected third-party issuing:
1. A cheap or free certificate validating only your domain.
2. A more expensive “Extended Validation” certificate which also validates your organization.

If you sign your own certificates, your website will generate warnings when anyone visits it. Users can choose to dismiss them, but more commonly, they will be more likely to navigate away from the website. For this reason, self-signed certificates are never recommended for a public website. Self-signed certificates provide no inherent trust that they are legitimate (anyone can generate one and pose as your site). They look amateurish and are annoying to the end user. Self-signed certificates should only be used in internal or test environments.

When ordering a certificate from a trusted third-party authority, there are various types that you can order. The cheapest ones are called domain-validated certificates. These work by emailing your domain administrator a validation link. Once verified, the certificate is awarded. These domain-validated certificates are acceptable and provide excellent security; however, as no humans are directly involved in the validation process, it may be easier for an attacker to get an illegitimate certificate by gaining control of the admin’s inbox or via other methods.

You can also order Extended Validation certificates. They cost more because real people validate the organization and your domain ownership. They make phone calls and ensure that everything looks right. If you have one of these certificates, your browser’s address bar turns green (or displays a lock symbol) when visitors come there to indicate that this site is trusted. If you want to maximize trust and make it easy for your end-users to identify your site as legitimate, you should use an Extended Validation certificate. These cost more but are well worth it in terms of security and trust. If EV certificates are outside your budget, you should still use an SSL certificate from some trusted third party.

Securing Web Forms with SSL

Once your website has an SSL certificate installed by a web host, your web pages can be accessed with addresses that start with “https://” instead of just “http://.” The “s” in “https” means “secure.” Note:

When connected to a web page using a secure address like “https://yourdomain.com,” the web browser will show a lock icon to inform you that the connection is secure.
Web pages that end in “.shtml” are not necessarily secure. The “s” means “server” (i.e., server-parsed page) and not “secure.” So, for example, “http://yourdomain.com/index.shtml” is not a secure page, but “https://yourdomain.com/index.html” is a secure page.
With SSL enabled, you can access the same page securely and insecurely in many default web server configurations. Both “http://yourdomain.com/form.html” and “https://yourdomain.com/form.html” work and show the form — the only difference is the use of SSL or not.

So, let’s say that you have a web form located at “http://yourdomain.com/form.html.” You have an SSL certificate, and your web host has installed it. Next, you want to:

Make sure people connect securely to the form page.
Make sure that no one can connect to the form page insecurely.

These two goals might sound the same, but they are not.

Enforce Secure Connections to Form Pages

Since regular website pages may be insecure, you need to ensure that the links to the secure form page are absolute links starting with the prefix “https://.” This will ensure that anyone clicking these links will be taken to the form page on a secure connection.

The best solution is to use an HSTS (HTTP Strict Transport Security), which tells browsers that they should always use the secure version of your website. If you choose to have both the insecure (http) and secure (https) versions of your site running at the same time (not recommended), then you need to be careful with linking so that sensitive pages are secured:

Wrong Links: Relative links are not recommended because, if the user is on an insecure page, relative links will always take them to insecure versions of the destination page. So relative links like the following should be avoided:

Fill out my form!

Correct Links: Absolute links will ensure a secure connection by specifying that SSL must be used via the link prefix “https://.”

For example: <a href=”https://yourdomain.com/form.html”>Fill out my form!

Be sure that all links to all secure pages of the site use this secure format with the “https://” prefix.

Side Note: These days, it is recommended that you use SSL for all website pages, not just ones that process sensitive information. This is good for user trust, security, and privacy. It is also good for Search Engine Optimization (as Google will reward you for securing your site). If you set up your site so all pages are always secure, relative links are safe.

Ensure No One Can Connect to Form Pages Insecurely

Using the above suggestions, all the links on your website will take users to the secure version of the form. However, most web hosts leave the insecure version of the form there, and users can still access it if they enter the insecure address directly (or if links are directed to the insecure page). As a next step, you should ensure that accessing the form page via an insecure connection is impossible.

There are several different ways that this can be done. Some of these include:

Separate space for SSL pages: If your web host has this feature, you can configure the website to store web pages for secure (SSL) connections in a different directory from those for insecure pages. If this feature is enabled, the form page is placed in the secure directory and no copies are in the insecure directory. Thus, any insecure requests for these pages would result in a “page not found” error. You could then implement server-side redirection rules where if someone requests the insecure page, they are automatically redirected to the secure version (this can be done using .htaccess files and the “Redirect” directive). If you did this, secure and insecure requests for the page would take the user to the secure version with no errors, warnings, or issues for the end user.

Scripted pages: If the form page is generated by a server-side script (i.e., PHP, Perl, Python, or JAVA), then the script itself can determine if the request is secure or not (e.g., by looking at the server environment variables). For secure requests, it can render the form as usual. The user receives an error for insecure requests or is redirected to the proper secure location.

Securing all pages: (Recommended) The site can be configured to automatically redirect all requests for insecure pages to the respective secure page. All pages will be secure, and any accidental/incorrect requests for the insecure pages will still get people to the right place. Security is greatly improved if you have set this up.

If my form is posted to a secure form processing script, why does it need to be secured?

This question is usually asked when a third-party manages the form processing. Is securing the form itself with SSL needed?

The answer is based on the following facts:

The data sent from end-users to the server will be secure and encrypted during transmission. This is critical for creating secure websites and forms that require HIPAA compliance.
Non-technical end-users will only know if their data is securely submitted once it is done. Many end-users will refrain from submitting sensitive data to an insecure form on your site.
End-users cannot know if they are viewing your website or a phishing site or if eavesdropping and modification are happening. Many users will not trust the connection and will not want to submit their data through your site if it appears insecure.
If your form page is insecure, it is straightforward for any malicious party to perform a man-in-the-middle attack to eavesdrop on connections, modify your form in transit to change what is collected and where the data is sent, and set up phishing sites. Your end-users can’t tell if this is going on.

If you do not secure your web form with SSL, it is vulnerable to attack. If nothing is going on, you can rely on transmission security. However, that minimal level of security is not recommended for production websites or anywhere that compliance is required.

Other Aspects of Creating Secure Web Forms

Proper use of SSL for encryption and trust is only part of creating secure website forms. You must be concerned with many other aspects to protect your users, your application, and your company’s reputation. These include (but are not limited to):

1. Cross-Site Scripting (XSS). Suppose you include dynamic content on your web pages (i.e., information submitted by other users or content submitted via form fields), and that content is not cleaned of JavaScript and HTML. In that case, bad actors could make arbitrary content appear on your website, capture user data, or worse. All data displayed should be clear of undesirable content (script tags, special characters, HTML, and other things). This is one of the most significant security issues with dynamic web pages across the internet.

2. Secure Server-Side Programming: The scripts and programs that accept and process the data from online forms must be created with security in mind. They must validate all submitted data as needed without making assumptions about its format and content. The scripts must not provide avenues for attacks like SQL Injection. Scripts must not use submitted content as actual filenames or URLs for remote loading content. They should log any strange errors or problems for later analysis. They should provide a mechanism for blocking undesirable actions or users from using the scripts.

3. Validation: Validation of all input data is part of the above two points. However, it is so essential that we will repeat it and go over some of the fundamental points:

If you validate submitted content, always perform your validation on the server side. Even if you use JavaScript to validate the data on the client side, you should always re-validate it on the server side. Why? Because people can get around JavaScript and submit arbitrary content directly to your scripts. The scripts should be prepared to handle that.
Always de-taint submitted data. What does that mean? It means never trust submitted data and take pains to ensure that the submitted data matches what you expect. For example, if you have a select list that sends your script a number as the value, do not assume you are getting a number. Instead, check that it is a numeric value or convert whatever is submitted into a number.
Remove disallowed content from the text submitted by users. Remove or block special characters, embedded codes, and other things that should not be there.
Ensure the submitted data is manageable enough to be used.
Do not assume anything — program defensively.

4. Preserving State with Hidden Form Fields or Cookies: If your program remembers information from one page to another by saving the data in hidden form fields, then your program must also ensure that the content of those fields was not tampered with. One good way to do this is to make a hash of all the data, together with a secret value, and include that hash in the form data. Then, when the form is submitted, you can recompute the hash and compare it with what passed from the form. If they match, you are okay; if they do not, the data has been tampered with. No one can break this scheme without knowing your secret value or breaking your hashing algorithm. This method can also be used to validate data saved in cookies. You can go further and use time stamps to prevent replay attacks.

5. Third-Party Applications: If you install programs from third parties on your website, you must ensure there are no known security issues with these programs, and you must be sure to update these programs as soon as new versions are released. If you let your website languish with an older, vulnerable version of a program, it will become a target for hackers as they constantly search the internet for such websites. Your site will likely be hacked in these cases, possibly causing loss of business, deactivation of your website, and tarnishing your website’s reputation. Using a third-party application is easy, but you need to select a good one that places the burden of keeping it updated on you. An exception is using a third-party application hosted by the third party itself. In these cases, the third party ensures that the program is continuously updated with anything needed to address any security issues. The burden is on them and not you. If you choose a good, respectable vendor, you should have no problems.

All these things, and more, are critical to developing a secure web application.

Securing the Form Data After Submission

Ensuring that users’ data is transmitted securely to your web server is critical, as is ensuring that your application is secure and will not be hacked. To secure sensitive data, you must understand what happens to that data after your program receives it. Many people forget that transmitting the data from the web server may require just as much preparation as receiving it from their users in the first place.

In the following subsections, we will look at three different ways of saving and retrieving your users’ data. In each case, we will explain what is needed to secure the data in your systems.

Send Form Data via Email

The most common action data processing scripts do is email the submitted data to the website owner’s email address. The website owner knows when there are new submissions by checking their email and can access the data immediately. Most people running websites check their email reasonably often, which integrates well with their business operations.

However, the standard ways of sending emails are entirely insecure. So, how can you use email while ensuring the data is secure and viewable only by the intended recipient?

Have your website script encrypt the data.
Send this encrypted data (or a link to download the encrypted data) to the intended viewers via regular email.

As the form data is encrypted within the email message, most insecurities inherent in email are obviated. You can also use secure third-party services to have your form data emailed to you securely without programming anything yourself.

Save the Submission in a Database

Many website owners like to save the submitted form data in a database (even if it is also emailed to someone). Why?

The data is saved online and potentially accessible from anywhere.
If the emailed copies of the data are lost, the copies in the database are still there.
The database can be accessed through a web browser with a suitable user interface.
The data is typically backed up and can be restored.

If storage in an online database is for you, then you need to:

Use encryption, like SSL or PGP, to ensure the data is securely stored in the database. Why? The contents of database tables are not encrypted or secure in general. Storing unencrypted data makes it available to anyone with access to the database or its backups.
Provide a user interface that allows you to access the database data. It must be secure, have robust access controls, and provide a means for decrypting the data.

The database option requires much work to make a secure and usable solution. For this reason, most small organizations do not end up using secure database storage for important form data.

Save the Data in Files

The file storage option is the “quick and dirty” alternative to secure database storage. Essentially, your program will:

Make a file containing the form data.
Encrypt that file using PGP or SSL.
Save that encrypted file in a directory on the web server that is not accessible from the website. Another option is to save it in an online file-sharing service.

Then, the website owners can log in to the web server using Secure FTP and download these files as needed. They can be decrypted locally when the data must be accessed. Other simpler data access mechanisms are available if the files are saved in an online file share.

This solution is secure and provides an excellent backup to securely emailed data.

Other Technical Tips for Creating Secure Website Forms

There are many other considerations in developing and maintaining a secure website and forms. It would be impossible to cover or even list them all. However, here are some more interesting and valuable tips.

Use Secure Cookies

If your secure site uses cookies for anything, set the “secure” cookie and the “httpOnly” flags. This will ensure that these cookies are never sent insecurely over the internet when the visitor arrives at any insecure pages of your website (they are not sent at all to insecure pages) and thus helps preserve the security of the contents of these secure cookies.

Prevent Form Spam

Form spam occurs when automated programs find your web forms and try to send spam through them. Form spam can result in hundreds or thousands of useless form posts daily. Once you start getting form spam, stopping it is a priority. There are two primary ways to help prevent spam:

CAPTCHA – This method requires end-users to read text embedded in an image and type that text successfully into a form field. The back-end program then validates this. Since most spam programs cannot read text embedded in images, it will successfully block almost all automated forms spam. However, CAPTCHA requires the users to perform one more step, which can be annoying.
JavaScript and Cookies – Most automated form spam programs do not process JavaScript or use cookies. If your web form requires JavaScript to submit the form successfully, bots cannot do this, and most form spam will be blocked. This method is less reliable than CAPTCHA but does not require any extra work from the end-user. Note that if you wish to use the JavaScript method, you must be sure that arbitrary submissions to the default action URL of your forms will never succeed—only submissions made after the execution of your custom JavaScript should succeed.

Minimize the Need for Trust

A good rule of thumb is to minimize the need to trust third parties and trust only the trustworthy.

If you do not trust your internal IT staff, do not host your web application on your servers or give them access to the server used.
If you do not trust the third-party hosting your website, encrypt the form data as soon as possible. This helps ensure that the data is not saved anywhere in plain text and is not backed up in plain text, thus minimizing your exposure to unauthorized people. Further, ensure that the private keys and passwords needed to decrypt the data are not stored on the web host’s servers.
Ensure that only authorized staff can access the submitted form data. Ideally, it should always be encrypted, and only authorized people should be able to decrypt it.

These are just a few obvious points. As you evaluate your web application and data flow, ask yourself, “Who can access the raw data and how?” at each stage. Are there stages where you are trusting people who should not be trusted?

Forced use of strong encryption in SSL

The strength of encryption used by SSL is a function of both the user’s web browser and the server. Even if your web server supports excellent encryption, like AES256, the user’s browser may choose a weaker level of encryption. Older versions of Internet Explorer are notable for choosing weaker encryption in the interest of speed.

You can modify your web server configuration so that only levels of encryption you approve can be used to access your site.

Use Two-Factor Authentication

Two-factor authentication is standard on very secure sites now. You require a password and something else (a code or token) to validate their identity. With both, the user can log in. Avoid using only SMS texting as the second factor, which is no longer considered secure.

LuxSci High Email Deliverability Best Practices Paper

What you’ll learn:

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

April 15, 2026
Pete Wermter

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

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

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

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

Let’s go deeper!

What Is Zero Trust Email Security in Healthcare?

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

This means:

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

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

Why Email Is a Critical Gap in Zero Trust Strategies

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

This is a major problem.

Email is where:

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

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

Healthcare Challenge: Personalized Communication and PHI Risk

Modern healthcare ecosystems are highly distributed:

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

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

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

The result is a growing tension between:

Security and compliance
Usability, engagement, and better outcomes

From Static Encryption to Intelligent, Adaptive Protection

Traditional email encryption methods often rely on:

Manual triggers
Static rules
User judgment

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

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

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

Aligning Zero Trust with HIPAA and Emerging Frameworks

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

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

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

PHI Protection Starts with Email

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

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

Here are 3 tips to stay on track:

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

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

What Sets B2B Marketing In The Healthcare Industry Apart?

April 14, 2026
Kai Haughney

B2B marketing in the healthcare industry runs through a buying environment shaped by review, caution, and internal scrutiny. A vendor may catch interest quickly, yet a deal still has to survive procurement, legal input, operational questions, and, in some cases, clinical oversight. That changes the tone and structure of effective outreach. Buyers want clear information, credible framing, and content that holds up when shared across teams. Strong campaigns account for those conditions from the first touch, giving decision makers useful material at the right point in the conversation.

How B2B marketing in the healthcare industry differs from other sectors

Healthcare buying carries a heavier internal burden than many commercial categories. A decision can affect patient related workflows, staff time, data handling, vendor risk, and budget planning all at once. That wider impact shapes how people read. A finance lead may scan for commercial logic and resource use. An operations leader may think immediately about rollout pressure and process disruption. An IT contact may focus on access, integration, and control. Messaging has to stand up to each of those viewpoints. That is why strong healthcare outreach tends to move with more restraint, more clarity, and more attention to proof than campaigns built for faster sales environments.

Trust within B2B marketing in the healthcare industry

Trust grows through judgment on the page. Buyers notice inflated language very quickly, especially when it appears in sectors where risk and accountability are part of everyday work. A polished headline can attract attention, though the body copy still has to carry weight. Clear examples help. Plain explanations help. So does a tone that sounds measured enough for someone to forward internally without hesitation. A payer team may want to see how a service affects review speed or administrative flow. A provider group may care about intake, coordination, or staff workload. A supplier may look for signs that communication across partners will become smoother and easier to manage. Credibility builds when the writing shows a close read of the reader’s world.

Buying committees do not think alike

Most healthcare deals are shaped by several people with different pressures attached to their roles. Procurement may be looking for vendor reliability and a smoother approval process. Compliance may read for privacy exposure and documentation. Operations may focus on practical fit with current workflows. Finance may want a clearer commercial case before the conversation goes any further. Those concerns do not compete with one another so much as stack on top of one another, which is why broad messaging tends to flatten out. Better campaigns anticipate that mix. One sequence can speak to efficiency and team workload. Another can support legal and compliance review. A third can frame the economic rationale in language senior stakeholders will recognise immediately.

Content that helps a deal move

Healthcare content earns its place when it gives buyers something they can use, discuss, and circulate. A short article on referral bottlenecks can help an operations lead frame the problem more clearly. A concise guide to secure communication can help internal teams ask better questions during review. A comparison page on implementation models can help a buyer weigh practical tradeoffs before a call is even booked. Useful content creates momentum because it fits the way decisions are made. It enters the conversation early, gives people sharper language for internal discussion, and keeps the subject alive between meetings. That is where strong work starts to separate itself from content written simply to fill a calendar.

Measuring progress with better signals

Healthcare teams get a clearer picture when they look past surface numbers and pay attention to the signs attached to real interest. Repeat visits from the same account can matter more than a large burst of low value traffic. A reply from an operations contact may tell you more than a high open rate. Visits to implementation, privacy, or procurement pages can indicate that the discussion is moving into a more serious stage.

Patterns like these help commercial teams judge where attention is gathering and where timing is starting to matter. Good B2B marketing in the healthcare industry supports that process by creating sharper entry points for sales, stronger context for follow up, and a more informed path from early curiosity to active evaluation.

Why Does B2B Healthcare Email Marketing Matter To Healthcare Buyers?

April 14, 2026
Erik Kangas

B2B healthcare email marketing is the practice of using email to reach healthcare business audiences with timely, relevant communication that supports trust, evaluation, and purchase decisions. In healthcare, that means more than sending promotional copy. Buyers want proof that a vendor understands procurement realities, privacy expectations, clinical workflows, and the pace of internal review. When the message is well judged, email helps move a conversation forward without forcing it. It can introduce a problem, frame the business case, and give decision makers something useful to circulate inside the company while they weigh next steps.

What makes B2B healthcare email marketing work in real buying cycles?

The difference between ignored email and useful email is context. Healthcare deals rarely move on impulse, and very few readers want a sales pitch in their inbox after one click or one download. Good B2B healthcare email marketing takes its cues from where the buyer is in the process. A first touch might define a problem in plain terms. A later message may explain implementation questions, privacy considerations, or internal adoption issues. That sequencing matters because healthcare buyers read with caution. They are not just asking whether a product looks good. They are asking whether it can survive legal review, procurement review, and scrutiny from the teams who will live with it day after day.

How does compliance shape B2B healthcare email marketing?

Healthcare email lives under closer scrutiny than email in many other industries. If a campaign touches protected health information, HIPAA enters the conversation immediately, especially the Privacy Rule and Security Rule. Even when outreach is aimed at business contacts, teams still need a disciplined view of what data is stored, who can access it, and how consent, opt out, and message content are handled.

The CAN SPAM Act also matters because sender identity, subject line accuracy, and unsubscribe function are not small details. Strong B2B healthcare email marketing treats compliance as part of message design from the start. That leads to cleaner copy, better internal approval, and fewer edits after legal teams step in.

Which audiences respond best to B2B healthcare email marketing?

Healthcare buying groups are rarely made up of one decision maker. A payer executive may care about administrative efficiency and audit readiness. A provider operations leader may be focused on referral flow, patient intake, or staff time. A supplier may look at partner communication, order handling, or data movement between systems. B2B healthcare email marketing works better when each audience receives language that matches its concerns instead of one generic message sent to everyone. That does not require jargon. It requires precision in the everyday sense of the word. Readers need to feel that the sender understands the pressures attached to their role, not just the industry label attached to their company.

What kind of content earns trust instead of quick deletion?

Healthcare buyers respond well to emails that help them think clearly. A short note that explains why referral leakage happens will land better than a vague message about transformation. A concise example showing how a health plan cut review delays can do more than a page of inflated claims. This is where B2B healthcare email marketing becomes persuasive without sounding pushy. The best messages teach, but they also move. They give the reader one useful idea, one practical example, and one reason to keep the conversation alive. That balance matters because healthcare readers are trained to be skeptical, and skepticism is not a barrier when the content respects it.

How can teams judge whether the program is doing its job?

Open rate alone does not say much in a long healthcare sales cycle. A better read comes from the quality of replies, the number of relevant page visits after a send, the movement of target accounts through the pipeline, and the way contacts share content internally.

B2B healthcare email marketing earns its place when it helps sales teams enter conversations with better timing and better context. If email is drawing the right people back to security pages, implementation pages, or procurement material, that is a useful signal. The real win is steady progress with buyers who need time, evidence, and confidence before they move.

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.

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.

What You Need to Know About PHI Identifiers

November 5, 2024
Erik Kangas

It’s hard to understate the benefits of using protected health information (PHI) in your patient engagement efforts. By effectively leveraging PHI, you can create highly-targeted and personalized email marketing campaigns, which have greater potential to connect with your patients and customers – and drive your desired outcomes.

However, before diving in, it’s essential to be aware of HIPAA’s complex compliance requirements and how they govern healthcare organizations’ marketing communications. Chief among these considerations is the concept of PHI identifiers and the role they play in classifying and protecting sensitive patient data. With this in mind, let’s explore HIPAA’s 18 PHI identifiers

What is a PHI Identifier?

Before we detail the 18 different PHI identifiers, it’s crucial to first distinguish between what counts as PHI and what, in reality, is personally identifiable information (PII).

PHI (as well as its digital equivalent or electronic protected health information (ePHI)), is defined as “individually identifiable protected health information” and specifically refers to three classes of data:

An individual’s past, present, or future physical or mental health or condition.
The past, present, or future provisioning of health care to an individual.
The past, present, or future payment-related information for the provisioning of health care to an individual.

In short, for an individual’s PII to be classed as protected health information it must be related to a health condition, their healthcare provision, or the payment of that provision. So, a patient’s email address in isolation, for example, isn’t necessarily PHI. However when combined with any information about their healthcare – such as in a patient engagement email campaign – it would constitute PHI.

Put another way, as HIPAA is designed to enforce standards and best practices in the healthcare industry, it’s concerned with protecting health-related information. While the protection of general PII is of the utmost importance, that’s a significantly larger remit – and, consequently, one that’s shared by a variety of data privacy regulations covering different industries and regions (PCI-DSS, GDPR, etc.).

What are the 18 PHI Identifiers?

With the above background in mind, we now have a clearer understanding of what is classed as PHI and, as a result, what data needs to be de-identified. The HIPAA Privacy Rule provides two methods for the de-identification of PHI: the Expert Determination and Safe Harbour methods.

Expert Determination requires a statistical or scientific expert to assess the PHI and conclude that the risk of it being able to identify a particular patient is very low. Safe Harbour, meanwhile, involves systematically removing or securing specific data types to mitigate the risk of patient identification. It’s from the Safe Harbour method that we get the following 18 PHI identifiers:

Patient Names

Geographical Elements: street address, city, and all other subdivisions lower than the state.

Dates Related to Patient’s ID or Health History: eD.O.B, D.O.D, admission and discharge dates, etc.

Telephone Numbers

Fax Numbers

Email Addresses

Social Security Numbers

Medical Record Numbers

Health Insurance Beneficiary Numbers

Account Numbers

Certificate or License Numbers: as these can confirm an individual’s professional qualifications or credentials, and when combined with PHI, are exploitable by malicious actors.

Vehicle Identifiers: i.e., license plate and serial numbers

Device Identifiers and Serial Numbers: those belonging to smartphones, tablets, or medical devices, because they communicate with healthcare companies during provision and can be linked back to the patient

Digital Identifiers: namely website addresses used by healthcare companies that patients may visit (for healthcare education, event registration, etc.)

Internet Protocol (IP) Addresses: the digital location from where a patient’s device accesses the internet; this can be used to acquire subsequent PHI

Biometric Identifiers: e.g., fingerprints, voice samples, etc.

Full Face Photographs: in additional to other comparable images

Other Unique Numbers, Codes, or Characteristics: not covered by the prior 17 categories

As illustrated by the above list, HIPAA’s list of PHI identifiers is comprehensive, covering all aspects of an individual’s identity and digital footprint. In light of this, when handling patient data it’s crucial to use platforms and digital solutions that have been designed with the secure transmission and storage of PHI in mind.

HIPAA Email Rules: What You Need to Know

October 16, 2024
LuxSci

The Health Insurance Portability and Accountability Act (HIPAA) is a complicated law that defines the standards for the secure collection, transmission, and storage of protected health information (PHI). When information is stored or exchanged electronically, the HIPAA Security and Privacy Rules require covered entities, i.e., organizations that handle PHI, to safeguard its integrity and confidentiality.

One of the most common ways that PHI is shared electronically is via email, so understanding HIPAA email rules is essential for achieving compliance and protecting sensitive data.

The HIPAA Email Security Rule

It’s important to note that HIPAA does not require the use of any specific technology or vendor to meet its requirements. Generally speaking, the Security Rule requirements for email fall into four categories:

Organizational requirements state the specific functions a covered entity must perform, including implementing policies, procedures and obligations concerning business associate agreements (BAAs).
Administrative requirements relate to employee training, professional development, and management of PHI.
Physical safeguards encompass the security of computer systems, servers, and networks, access to the facility and workstations, data backup and storage, and the destruction of obsolete data and HIPAA email archiving.
Technical safeguards ensure the security of email data transmitted over an open electronic network and the storage of that data.

Let’s move on to discussing some of the main requirements that apply to email and the steps you need to take to secure email accounts that transmit and store PHI.

HIPAA Email Rules: Compliance Checklist

While encryption gets most of the spotlight during discussions on email security, the HIPAA email rules, in contrast, cover a range of behaviors, controls, and services that work together to address eight key areas:

Access
Encryption
Backups and Archival
Defense
Authorization
Reporting
Reviews and Policies
Vendor Management

Let’s look at each aspect of HIPPA’s email rules in greater detail.

1. Access

Access controls help safeguard access to your email accounts and messages. Implementing access controls is essential to keep out unauthorized users and secure your data, with key steps including:

Using strong passwords that cannot be easily guessed or memorized – and changing them frequently, e.g. every 30 days.
Creating different passwords for different sites and applications.
Enabling multi-factor authentication (MFA).
Securing connections to your email service provider using TLS and a VPN.
Blocking unencrypted connections.
Pre-emptively installing software that remotely wipes sensitive email off your mobile device when it is stolen or misplaced.
Logging off from your system when it is not in use and when employees are away from workstations.
Emphasizing opt-out email encryption to minimize breaches resulting from human error.

2. Encryption

Email is inherently insecure and at risk of being read, stolen, intercepted, modified, and forged (repudiated). Covered entities should go beyond the technical safeguards of the HIPAA Security Rule and take steps that exceed what is required to futureproof their communications. Email encryption features to adopt include the following:

The ability to send secure messages to anyone with any email address.
The ability to receive secure messages from anyone.
Implementing measures to prevent the insecure transmission of sensitive data via email.
Exploring message retraction features to retrieve email messages sent to the wrong address.
Avoiding opt-in encryption to satisfy HIPAA Omnibus Rule.

3. Backups and Archival

HIPAA email rules require copies of messages containing PHI to be retained for at least six years. In light of this, organizations must consider the following:

How are email folders backed up?
Are there at least two different backups at two different geographical locations? Additionally, the processes updating these backups should be independent of each other as a measure against backup system failures.
Have you maintained separate, permanent, and searchable archives? While the emails should be tamper-proof, with no way to delete or edit them, they should be easily retrievable to facilitate discovery, comply with audit requests, and support business-critical scenarios.

4. Defense

Cyber threats against healthcare organizations are continually on the increase. Some may be surprised to learn that HIPAA compliant email rules mandate that organizations take steps to defend against possible malicious actors. With this in mind, consider implementing the following technologies:

Server-side inbound email malware and anti-virus scanning to detect phishing messages and malicious links.
Showing the sender’s email address by default on received messages.
Email filtering software to detect fraudulent messages and ensure it uses Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting and Conformance (DMARC) information to classify messages.
Scanning outbound email.
Scanning workstations for malware, i.e., viruses, ransomware, etc.
Using plain text previews of your messages.

5. Authorization

A critical aspect of HIPAA’s email rules is ensuring that cybercriminals cannot impersonate your company or employees. Configuring your domains with SPF and DKIM is essential to verify your identity as an authorized sender of mail from your domains. Also, ensure that users cannot send messages through your email servers without authentication and encryption.

6. Reporting

Setting accountability standards for email security is essential to establishing and strengthening your HIPAA compliance posture. Important steps to take include:

Creating login audit trails.
Receiving login failure and success alerts.
Auto-blocking known attackers.
Maintaining a log of all sent messages.

7. Reviews and Policies

Humans are the greatest vulnerability to any security and compliance plan, so creating policies and procedures that focus on plugging vulnerabilities and preventing human errors is essential. Strategies for reducing risk include:

Inviting independent third parties to review your email policies and user settings. Fresh, unbiased eyes can discover existing issues quickly.
Preventing devices that connect to sensitive email accounts from connecting to public WiFi networks.
Creating email policies prohibiting users from clicking on links or opening attachments that are not expected or requested.

8. Vendor Management

Most companies do not manage their email in-house, so it’s crucial to thoroughly research and vet whoever will be responsible for your email services. Perform an annual review of your email security and stay on top of emerging cybersecurity threats to take proactive action and for continued compliance with HIPAA email rules.

LuxSci’s secure high-volume email and marketing solutions are designed to help healthcare organizations tackle complicated HIPAA email rules and automate the compliance process.

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.
