LuxSci vs. Zix Webroot: Choosing the Right HIPAA Compliant Email Provider

HIPAA Compliant Email
Pete Wermter
March 6, 2025

There are many crucial factors to consider when developing and executing successful healthcare communication campaigns. First and foremost, you must ensure the protected health information (PHI) under your organization’s care is handled securely, as mandated by Health Insurance Portability and Accountability Act (HIPAA) regulations, which begins with selecting the right HIPAA compliant email provider for your company’s needs.

With the right email services provider (ESP) in place, healthcare providers, payers, and suppliers can confidently use PHI in their patient and customer engagement campaigns – safe in the knowledge they’re aligned with HIPAA’s tight regulatory guidelines.

To help you choose the best HIPAA compliant email provider for your healthcare organization’s email outreach objectives, this post compares two of the most well-known HIPAA compliant services on the market: LuxSci and Zix Webroot (from here, simply referred to as Zix).

Comparing each email provider’s performance on several criteria, we’ll help you decide which solution best fits the needs of your healthcare organization and will help you better engage with your patients and customers.

LuxSci vs. Zix: Evaluation Criteria

In our evaluation of LuxSci vs. Zix, we’ll be using the following criteria:

Data Security and Compliance: undoubtedly the most important factor when it comes to ensuring HIPAA-compliant email communication within healthcare organizations, this reflects the extent to which each platform secures sensitive patient data as per HIPAA’s regulations.
Performance and Scalability: the email platform’s ability to facilitate high-volume email communication campaigns, which also, subsequently, encompasses the platform’s throughput and how well they’re able to scale in line with an organization’s needs.
Infrastructure: if the email service provider has the necessary security infrastructure in place to both adequately safeguard PHI and support bulk email marketing campaigns.
Marketing Capabilities: if the platform provides features that allow you to personalize and refine your patient engagement strategies.
Ease of Use: how easy each email service is to use; a deceptively important factor in light of the urgent need for employee cyber threat awareness training.
Other HIPAA-Compliant Products: if the platform offers complementary features that aid healthcare organizations with their broader patient engagement, and growth, objectives.

Now that we’ve covered the criteria by which we’ll be assessing each email platform, let’s compare LuxSci vs Zix to determine which is the best fit for your company’s needs.

LuxSci vs. Zix: How Do They Compare?

Data Security and Compliance

LuxSci prides itself on being a fully HIPAA-compliant email service provider, offering end-to-end, flexible, and automated encryption, giving it an advantage in the protection of patient data in the event of its exfiltration by cyber criminals. Additionally, LuxSci is HITRUST-certified, illustrating its additional commitment to data privacy legislation and the securing of PHI.

Zix is also fully HIPAA-compliant and, consequently, enables the use of PHI to personalize your email communications. That said, Zix doesn’t offer as many encryption options as LuxSci. Most notably, Zix doesn’t enforce Transport Layer Security (TLS) encryption or enable automated encryption. The absence of these features means that a healthcare organization’s security teams must perform more manual oversight when it comes to encryption of PHI, increasing the chance of human error.

Performance and Scalability

While Zix supports large email campaigns and provides detailed reporting functionality, LuxSci is the more prudent choice for high-volume email marketing campaigns.

LuxSci maintains the necessary infrastructure to ensure the reliable delivery of hundreds of thousands to millions of emails per month (i.e., throughput – 1000s of emails per hour), all while adhering to HIPAA’s strict guidelines on preserving patient privacy.

Infrastructure

In the same way that LuxSci have advantages over Zix on data security capabilities, it performs well in this category too, which makes sense, as the two factors are interwoven.

While offering a range of customary multi-tenancy infrastructure setups, Zix doesn’t accommodate dedicated, or single-tenancy, infrastructure options – for companies who can’t afford to depend on the security postures of the companies with whom they share servers. Zix, in line with its ability to facilitate large patient or customer engagement campaigns, provides enterprise-scale scalability.

Zix also provides high availability and robust disaster recovery capabilities, so healthcare organizations can retain their operational capabilities in the event of a cyber attack. Or, alternatively, an unforeseen physical disaster that compromises a company’s infrastructure (power outages, fires, storms, intentional damage, etc.).

That said, LuxSci possesses all these features in addition to more comprehensive single-tenancy options, scalability, and secure email hosting.

Marketing Capabilities

As with our comparisons of LuxSci against email platforms like Paubox and Virtru, it’s somewhat futile to compare each platform’s marketing capabilities – as neither LuxSci or Zix are marketing platforms, in the vein of Adobe Campaign or Oracle Eloqua, for example.

That said. LuxSci provides a HIPAA compliant marketing solution, offering automation, for streamlining email marketing campaigns, and, personalization options, for more engaging email communication campaigns.

Ease of Use

Both LuxSci and Zix perform admirably in this category, but the edge goes to Zix, as LuxSci implementations often involve the complexities that come with large-scale, high volume use cases.

LuxSci, however, is known for offering best-in-class customer support backed by HIPAA security experts, honed as a result of over 25 years of facilitating and supporting email communication strategies for healthcare organizations of all sizes.

Other HIPAA-compliant Products

With secure texting functionality, secure forms for HIPAA compliant data collection, and secure file sharing, LuxSci ranks well in this category. Zix, in contrast, provides only secure file sharing – though, because of Zix Webroot’s capabilities, offers superior secure file sharing to LuxSci.

What you’ll learn:

Your Email Platform Is Becoming Critical Healthcare Infrastructure

July 1, 2026
Pete Wermter

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

Today, however, that view is rapidly becoming outdated.

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

Email Is No Longer Just a Messaging Tool

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

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

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

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

The Stakes Continue to Rise

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

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

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

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

AI Is Raising the Bar Even Higher

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

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

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

Generating more personalized emails means little if organizations cannot:

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

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

Infrastructure Matters More Than Features

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

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

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

Questions increasingly include:

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

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

Email and the Future Of Secure Healthcare Communications

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

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

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

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

June 9, 2026
Pete Wermter

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

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

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

Where Things Stand Today

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

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

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

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

The Growing Focus on Mandatory Email Encryption

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

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

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

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

This is particularly important for email communications.

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

What Healthcare Organizations Should Do Now

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

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

Key areas to review include:

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

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

Why Secure Email Encryption Should Be a Priority

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

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

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

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

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

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

The Bottom Line

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

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

The time to prepare is now!

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

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

Is OCR Already Enforcing Email Encryption Under the New HIPAA Security Rule?

May 12, 2026
Pete Wermter

Healthcare organizations waiting for the final HIPAA Security Rule updates before improving email encryption and security may already be behind.

While the proposed changes to the HIPAA Security Rule are expected to be finalized in May, the direction from the U.S. Department of Health and Human Services Office for Civil Rights (OCR) is becoming increasingly clear. Across investigations, settlements, and enforcement actions, OCR continues emphasizing stronger technical safeguards, encryption, documented security programs, multi-factor authentication (MFA), risk analysis, and proactive cybersecurity operations.

For healthcare organizations, one area stands directly in the middle of all of these priorities: email.

Email remains a primary communication channel in healthcare — and one of the industry’s largest security vulnerabilities. From unauthorized PHI exposure to phishing attacks and ransomware delivery to account compromise, email continues to be at the center of healthcare cybersecurity incidents.

So, are the proposed HIPAA Security Rule changes hypothetical future guidance or a preview of OCR’s future enforcement expectations?

For healthcare email security, the implications are significant.

Email = Healthcare Cybersecurity Risk

Healthcare organizations rely on email for critical communications and healthcare workflows, including:

Patient communications
Care coordination
Claims and billing notifications
Marketing and engagement
Internal collaboration
Third-party vendor communications
Delivery of sensitive PHI

At the same time, attackers continue targeting email systems because they remain one of the easiest entry points into healthcare environments.

Insecure email workflows create unnecessary exposure of protected health information. Phishing campaigns are becoming more sophisticated. Credential theft attacks are bypassing traditional MFA methods. And business email compromise (BEC) attacks continue rising.

Recent OCR enforcement actions increasingly reflect these realities.

Organizations are being evaluated not simply on whether a breach occurred, but whether they implemented reasonable safeguards beforehand, including encryption, authentication controls, monitoring, access management, and documented risk mitigation processes.

For email systems specifically, that means healthcare organizations should expect increased scrutiny around:

Email encryption enforcement
MFA deployment
Audit logging and retention
Conditional access policies
Vendor security controls
Secure email delivery best practices
Segmentation and infrastructure isolation
Ongoing patch and vulnerability management

In many ways, email infrastructure is becoming a visible test of an organization’s overall cybersecurity posture.

Email Encryption Is Moving From Addressable to Required

Historically, healthcare organizations often interpreted HIPAA email encryption requirements with flexibility because encryption was technically categorized as an “addressable” safeguard under the Security Rule. But, OCR enforcement and broader cybersecurity realities are changing that interpretation rapidly.

Today, failing to encrypt sensitive healthcare communications increasingly creates both security and regulatory risk. The proposed Security Rule updates place even greater emphasis on encryption and technical safeguards. At the same time, OCR investigations continue examining whether organizations properly protected PHI in transit and at rest.

For healthcare email specifically, this creates several growing expectations:

Email encryption should be automated wherever possible
Human error should not determine whether PHI is protected
Organizations should maintain documented encryption policies
Secure delivery methods should adapt dynamically to recipient capabilities
Audit trails should demonstrate how messages were secured

At LuxSci, we have long believed that encryption should operate as a strategic layer of healthcare communications infrastructure, not as a manual user decision.

Our SecureLine email encryption technology automatically applies appropriate encryption methods based on organizational policies and delivery requirements, helping reduce the risks associated with human error while maintaining usability, deliverability and compliance. As enforcement expectations rise, this type of automated security enforcement is becoming increasingly important.

Traditional MFA May No Longer Be Enough

Another major shift emerging from both OCR enforcement trends and the proposed rule updates is the growing importance of stronger authentication models.

Healthcare organizations have historically viewed MFA deployment as sufficient protection. But attackers have adapted quickly.

MFA bypass attacks, token theft, session hijacking, and consent phishing campaigns are increasingly targeting healthcare users. As a result, regulators and cybersecurity experts are placing greater emphasis on phishing-resistant authentication approaches and contextual access controls.

For email environments, organizations should increasingly evaluate:

Whether MFA methods are resistant to phishing attacks
Conditional access policies based on device, location, and behavior
Account monitoring and anomaly detection
Administrative access protections
Session management controls
Logging and authentication auditing

The broader message is clear: healthcare organizations need authentication strategies designed for today’s threat landscape, not yesterday’s compliance checklist.

OCR Wants Proof, Not Just Policies

One of the clearest trends emerging from recent OCR activity is the increasing importance of documentation and operational evidence. Healthcare organizations must increasingly demonstrate not only that safeguards exist, but that they are consistently enforced, monitored, tested, and maintained over time.

For email systems, organizations should be prepared to demonstrate:

Email encryption policies
MFA enforcement records
Audit logs and message tracking
Vendor security documentation
Risk assessments involving email infrastructure
Patch management procedures
Employee security awareness training
Incident response procedures for email-based threats

This represents a broader shift in healthcare cybersecurity expectations.

The question is no longer: “Do you have email security controls?”

The question is increasingly: “Can you prove they are operationally effective?”

Healthcare Organizations Need a New Email Security Strategy

The healthcare industry is entering a new phase of cybersecurity enforcement.

OCR’s direction is becoming increasingly clear: organizations are expected to proactively secure systems handling PHI using modern, documented, and continuously maintained safeguards. For email security specifically, that means organizations should stop treating encryption, MFA, and secure communications as optional compliance requirements. Instead, they should view secure email infrastructure as a strategic component of enterprise cybersecurity and patient trust.

At LuxSci, we help healthcare organizations modernize secure communications with HIPAA compliant email infrastructure designed specifically for healthcare environments, including flexible encryption, secure delivery, auditability, high deliverability, access controls, and dedicated infrastructure options.

The proposed HIPAA Security Rule updates may not yet be final. But, OCR is already signaling where healthcare cybersecurity enforcement is headed next. For organizations relying on email to communicate with patients, members, customers, and partners, the time to examine your secure email infrastructure is now.

What are the Infrastructure Requirements For HIPAA Compliant Email?

April 3, 2025
Pete Wermter

Healthcare providers, payers, and suppliers increasingly rely on email communication for a wide variety of purposes pertaining to their patients’ and customer’s healthcare journeys. However, ensuring email messaging is both effective and HIPAA compliant requires the right infrastructure, including dedicated environments, high throughput and low latency, end-to-end encryption, scalability and compliance monitoring.

The Health Insurance Portability and Accountability Act’s (HIPAA) regulations mandate a series of data security and privacy requirements to safeguard the electronic protected health information (ePHI) contained in emails, which is a good place to start. At the same time, however, healthcare organizations must also consider deliverability best practices to ensure their messages successfully reach the intended recipients.

With all this in mind, this post discusses the infrastructure requirements for HIPAA compliant email. We’ll explore the differences between transactional and marketing emails, as well as infrastructure and compliance considerations for each.

What Are Transactional Emails?

Transactional emails are messages that correspond to a previous interaction between a healthcare organization and an individual. A patient or customer will trigger the delivery of a transactional email by taking a specific action – with the transaction email being confirmation of the action.

Examples of transactional emails include:

Explanation of Benefits
Billing statements
Invoices
Appointment confirmations and reminders
Order updates and shipping notifications
Password resets and security notifications
Plan renewal confirmation
Payment failure notifications
In-home care communications

Healthcare companies can also use transactional emails to communicate relevant instructions, next steps, or follow-up actions.

What Are Marketing Emails?

Marketing emails contain content designed to influence the recipient into taking a particular action, usch as ordering a new product or sign up for a new service. Subsequently, they often contain informational materials intended to educate the individual so they can make a more informed decision.

Examples of marketing emails include:

New product or service launches
Promotional offers
Loyalty reward notifications
Customer reviews and testimonials
Educational materials or campaigns
Preventative care outreach
Event Invitations
Re-engagement messages (e.g., “We Miss You!..”)

With the proper data safeguards and the effective use of ePHI, marketing emails can be personalized to be made more relevant to the recipient. This then allows patients or customers to be segmented into subgroups according to particular commonalities, e.g., age, gender, lifestyle factors, medical conditions, etc.

Opt-in Rules for HIPAA-Compliant Email Communication

One significant difference between marketing and transactional emails is that recipients must explicitly opt-in to receive marketing emails.

HIPAA requires explicit patient consent for marketing emails if they contain ePHI, requiring individuals to opt-in to receive email marketing communications from a healthcare organization. Neglecting to allow people to opt-in to your marketing communications leaves your company open to the consequences of HIPAA non-compliance, which include financial penalties and reputational damage.

Conversely, healthcare organizations aren’t required to obtain opt-ins to send transactional emails, but these communications are still subject to other HIPAA regulations, such as encryption and audit logging.

Additionally, marketing emails must comply with the CAN-SPAM Act: US legislation that governs commercial email communication and protects individuals from deceptive sales and marketing practices. The CAN-SPAM Act requires healthcare organizations to provide an opt-out mechanism in the event they no longer wish to receive marketing emails. Subsequently, you must always allow individuals to opt out of marketing emails to stay compliant.

Email Infrastructure Requirements For HIPPA-Compliance

As the vast majority of healthcare organizations need to send marketing and transactional emails, they must have the appropriate infrastructure to facilitate the optimal delivery of both types of emails. Consequently, for HIPAA compliant email, they need to establish the appropriate infrastructure configurations for each, according to their differing purposes, sending patterns, and compliance considerations.

Let’s look at the infrastructure requirements for each email type in turn, before looking at considerations that pertain to both types of email.

Key Transactional Email Infrastructure Considerations

Transactional emails are sent to a sole patient or customer, with the information therein only intended for that specific individual. Additionally, they can be highly time-sensitive: for example, a password reset or similar emails related to logins and service use must be immediate, while order confirmations need to be delivered ASAP to reassure clients of a company’s reliability and trustworthiness.

Accounting for this, the infrastructure requirements for transactional emails include:

High Speed and Low Latency: servers that are optimized for high IOPS (input/output operations per second) and minimal processing delays to ensure near-instant delivery
Dedicated IPs: this helps healthcare companies maintain a strong sender reputation to avoid blacklisting, being labelled as spam, etc. This is crucial for reliable, fast delivery.
High Availability and Redundancy: this includes load balancers, failover servers, and geographically distributed data centers to ensure comprehensive disaster recovery and more robust business continuity protocols.

Key Marketing Email Infrastructure Considerations

In contrast to transactional messages, marketing emails must often be sent out in high volumes, which could be as many as hundreds of thousands or millions per month. As a result, marketing email campaigns have different computational demands, i.e., CPU and storage, than transactional messages intended for a single person.

Subsequently, the infrastructure requirements for marketing emails include:

High Volume and Scalability: marketing messages require a larger throughput to facilitate the bulk delivery of email. Additionally, servers should scale easily to accommodate increasingly larger campaigns without suffering bottlenecks.
Queueing and Throttling: marketing email infrastructure must prevent sending surges that could trigger spam filters or overload recipient servers, which often results in blacklisting.
Dedicated vs. Shared Infrastructure: it’s important to consider whether to opt for private versus shared infrastructure, depending on the size of your organization and the scale of your campaigns. Large senders often use dedicated IPs for better control, while smaller companies or campaigns might use shared pools with strict sender reputation management.

Key Infrastructure Considerations for Both Types of Email

Lastly, there are infrastructure requirements that apply to both types of email that will help facilitate their fast and reliable delivery, respectively. These include:

Separate Infrastructure: consider hosting your transactional and marketing emails on separate servers. This benefits transactional emails in particular, as there are several factors inherent to marketing email campaigns, such as bounced emails and being flagged as spam, that affect an email IP’s reputation. Separate infrastructure maintains the integrity of a healthcare company’s IP address for transactional emails, ensuring they are delivered unimpeded.
Encryption: the ePHI in all email communications must be encrypted in transit, i.e., when sent to individuals, and at rest, i.e., when stored in a database. This helps safeguard the patient data within the message, regardless of its nature.
HIPAA Compliance Monitoring: remaining aware of what ePHI is included in email communications. This keeps data exposure to a minimum and mitigates the unintentional inclusion of patient data in email communications.
Logging and Auditing: this not only allows you to track email activity, but you also can measure the efficacy of your email communications, who accessed ePHI, and what they did with it. This is an essential part of HIPAA compliance and will be subject to tighter regulation when the updates to HIPAA’s Security Rule come into effect in late 2025.

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.

Is Google Web Hosting HIPAA Compliant?

December 11, 2024
Erik Kangas

Google web hosting is not HIPAA compliant as a standard service. While Google Cloud Platform can be configured for HIPAA compliance with a Business Associate Agreement (BAA), Google’s simpler hosting services like Firebase Hosting and standard Google Sites do not qualify for HIPAA compliance. Healthcare organizations looking to host websites containing protected health information need properly configured Google Cloud Platform environments with additional security measures in place.

Google Web Hosting Options and Limitations

Google web hosting includes several different services with varying capabilities. Google Cloud Platform provides enterprise-level infrastructure that can support healthcare applications when properly configured. Other Google web hosting options like Firebase Hosting offer simplified deployment but lack healthcare compliance features. Google Sites provides basic website creation tools without the security measures needed for patient information. Healthcare organizations must understand these distinctions when selecting Google hosting services. The default configurations of these platforms do not include the security protections required by HIPAA regulations.

Business Associate Agreements for Google Web Hosting

Healthcare organizations must obtain a Business Associate Agreement before using any Google web hosting service for protected health information. Google offers a BAA that covers specific Google Cloud Platform services but excludes many other Google web hosting options. This agreement establishes Google’s responsibilities for protecting healthcare data according to HIPAA requirements. Organizations must verify which specific services fall under BAA coverage before implementation. Google provides documentation listing covered services and compliance recommendations for healthcare customers. Services not covered by the BAA cannot legally store or process protected health information.

Required Security Configurations

Google web hosting requires specific security measures to achieve HIPAA compliance. Website data storage needs encryption both during transmission and while at rest. Access controls must limit system permissions to authorized personnel through proper authentication methods. Logging systems need to track user actions and system events for compliance documentation. Network security requires protection against unauthorized access through firewall rules and secure configurations. Organizations using web hosting for healthcare websites typically implement additional security tools beyond the default platform offerings. Many healthcare providers employ security specialists familiar with both Google environments and healthcare regulations.

Compliance Documentation Requirements

Using Google web hosting for healthcare websites demands thorough compliance documentation. Organizations must maintain records of their signed BAA with Google and service configurations. Security policies should outline how the hosting environment protects patient information. Risk assessments need documentation showing potential vulnerabilities and mitigation strategies. Access control policies establish who can work with healthcare data and under what circumstances. Incident response plans outline steps for addressing potential security breaches. These documents not only support HIPAA compliance but also provide guidance for technical staff maintaining the website infrastructure.

Alternative Hosting Approaches

Many healthcare organizations choose alternatives to Google web hosting. Specialized HIPAA compliant hosting providers focus exclusively on healthcare needs with pre-configured security measures. These providers often include compliance support services beyond basic hosting. Some organizations maintain healthcare websites on private cloud or on-premises infrastructure for maximum control. Hybrid approaches separate public information on standard hosting from protected health information on compliant systems. The choice between these options depends on organizational resources, technical capabilities, and specific website requirements.

Implementation Best Practices

Healthcare organizations implementing Google web hosting for compliant websites follow established best practices. Data mapping identifies exactly what protected health information appears on the website and where it resides within Google services. Security reviews examine hosting configurations before storing any patient information. Staff training ensures everyone managing the website understands compliance requirements. Regular security assessments identify potential vulnerabilities as technology evolves. Organizations typically establish monitoring systems to alert them about unusual activities that might indicate security issues. These practices help maintain compliance while providing effective web services to patients.

HIPAA-Compliant Email Marketing: FAQ

November 21, 2023
LuxSci

Email is an essential channel for most marketers. However, HIPAA regulations raise many questions for healthcare marketers who need to execute email marketing campaigns without violating patient privacy.

HIPAA is a complicated law that offers a lot of guidance but does not require the use of any specific technologies to protect patient privacy. The ambiguity causes a lot of confusion for marketers trying to integrate email into their marketing strategy. This article addresses some frequently asked questions about HIPAA-compliant email marketing and offers advice for securing patient data and futureproofing your marketing.

Do generic practice newsletters need to be protected?

Some marketers assume practice newsletters do not contain health information and, therefore, do not fall under HIPAA requirements. However, this assumption is often incorrect. Many are surprised to learn that protected health information can be implied from seemingly benign information.

In this way, many generic email newsletters often indirectly contain PHI because they are sent to lists of current patients. Email addresses are individually identifiable and combined with the email content; it may imply that they are patients of the practice. For example, say you send a “generic” newsletter to the patients of a dialysis clinic. An eavesdropper may be able to infer that the recipients receive dialysis. Therefore, the email reveals information about an individual’s health treatment, is PHI, and should be secured in compliance with HIPAA regulations.

In some cases, it can be complicated to determine what is PHI and what is not. Using a HIPAA-compliant marketing solution is best to avoid ambiguity and ensure security.

How Do I Find a HIPAA Compliant Email Marketing Vendor?

Unfortunately, using broadly popular email marketing platforms is not recommended. Many of these platforms were designed for e-commerce businesses and are not secure enough to meet HIPAA requirements. We do not recommend using a solution not specifically equipped to meet the healthcare industry’s unique security and compliance needs. To determine if your email marketing provider is compliant, they must meet three broad criteria at a minimum.

The vendor must sign a Business Associate Agreement outlining how they plan to secure your data and what they will do in the event of a breach.
Encrypt data at rest when it is stored in their systems.
Encrypt email messages and data in transit as it is sent to the recipients.

Not all vendors will be up to the task. Carefully vet your email marketing vendors to ensure they are taking steps to secure data and protect patient privacy.

What is an Email API?

API is an acronym that stands for “Application Programming Interface.” An email API gives applications (like CRMs, CDPs, or EHRs) the ability to send emails using data from the application. Email APIs also return campaign data to the platform or dashboards so you can assess the effectiveness of your marketing efforts. Trigger-based transactional or marketing emails are ideal for sending with an email API. In this situation, emails are sent when pre-determined conditions in the application are met. Healthcare organizations may use email APIs to send appointment reminders using electronic health records system data about a patient’s upcoming appointment.

Email APIs enable the automation of common email workflows. However, they are not interchangeable with email marketing platforms. Email APIs do not include the contact management systems standard in most email marketing platforms because all that data lives within the application they connect to. In addition, email API tools typically do not include drag-and-drop editor tools or other design features that help your emails stand out.

Does HIPAA permit providers to send unencrypted emails with PHI to patients?

Encryption is an addressable standard under the HIPAA Security Rule, but that does not mean it is optional. The HIPAA Privacy Rule does not explicitly forbid unencrypted email. Still, it does state that “other safeguards should be applied to protect privacy reasonably, such as limiting the amount or type of information disclosed through the unencrypted email.”

In addition, the Department of Health and Human Services also states that “covered entities are permitted to send individuals unencrypted emails if they have advised the individual of the risk, and the individual still prefers the unencrypted email.” Some organizations use waivers to inform patients of the risks and acquire permission to send unencrypted emails.

However, we do not recommend this approach for several reasons:

Keeping track of waivers over time and recording status changes and updates is challenging.
Signed waivers do not insulate you from the consequences of a HIPAA breach.
And finally, using waivers to send unencrypted emails doesn’t eliminate your other HIPAA obligations like data retention and disposal. Using a HIPAA-compliant solution is more manageable and eliminates ambiguity.

Can patients exercise their right of access by receiving PHI via unencrypted email?

Yes, but they must be fully informed of the risks and sign waivers acknowledging them. The caveats in the previous answer apply. It’s always better to utilize an encryption tool to protect patient data.

Is Microsoft 365 or Exchange 365 encryption sufficient for marketing emails?

Microsoft 365 can be configured with Office Message Encryption (OME) to comply with HIPAA. However, the program is not well-suited to HIPAA email marketing. OME primarily relies on portal pickup encryption, in which the message is stored securely on a server and requires the recipient to log in to the portal to read the email. If you are a marketer trying to increase engagement, the portal adds a barrier to access that many will not cross. Light-PHI marketing messages are best sent using TLS encryption. TLS-encrypted messages arrive in the recipient’s inbox just like a regular email and do not require a user to log in to read the message.

In addition, Microsoft 365 is not configured to send high volumes of email. If you plan to send large marketing campaigns, you could unintentionally disrupt regular business communications by sending all the messages through the same infrastructure. You should separate your business and marketing email sending to protect your IP reputation and achieve your desired sending throughput.

What are common email marketing use cases for healthcare?

Email marketing in healthcare is not restricted to boring practice newsletters. When you utilize tools that enable the use of PHI in your targeting and personalization efforts, the sky is the limit. With consumer preferences shifting toward digital communications, marketers willing to utilize the email channel and tactics like segmentation and personalization can see better results.

Email is an excellent way to communicate with patients. A sampling of ways that healthcare marketers can use email include:

engaging patients in their healthcare journey
educating patients about their healthcare conditions and treatments
improving attendance and scheduling
retaining patients
increasing preventative procedures
collecting data on the patient experience
improving patient satisfaction
