Know the Biggest Email Threats Facing Healthcare Right Now

biggest email threats

Due to its near-universal adoption, speed, and cost-effectiveness, email remains one of the most common communication channels in healthcare. Consequently, it’s one of the most frequent targets for cyber attacks, as malicious actors are acutely aware of the vast amounts of sensitive data contained in messages – and standard email communication’s inherent vulnerabilities.

 

In light of this, healthcare organizations must remain aware of the evolving email threat landscape, and implement effective strategies to protect the electronic protected health information (ePHI) included in email messages. Failing to properly secure email communications jeopardizes patient data privacy, which can disrupt operations, result in costly HIPAA compliance violations, and, most importantly, compromise the quality of their patients’ healthcare provision.

 

With all this in mind, this post details the biggest email threats faced by healthcare organizations today, with the greatest potential to cause your business or practice harm by compromising patient and company data. You can also get our 2025 report on the latest email threats, which includes strategies on how to overcome them.

Ransomware Attacks

Ransomware is a type of malware that encrypts, corrupts, or deletes a healthcare organization’s data or critical systems, and enables the cybercriminals that deployed it to demand a payment (i.e., a ransom) for their restoration. Healthcare personnel can unwittingly download ransomware onto their devices by opening a malicious email attachment or clicking on a link contained in an email.

In recent years, ransomware has emerged as the email security threat with the most significant financial impact. In 2024, for instance, there were over 180 confirmed ransomware attacks with an average paid ransom of nearly $1 million. 

Email Client Misconfiguration

While a healthcare organization may implement email security controls, many fail to know the security gaps of their current email service provider (ESP) or understand the value of a HIPAA compliant email platform, leaving data vulnerable to email threats, such as unauthorized access and ePHI exposure, and also, subsequently, a greater risk of compliance violations and reputation damage.


 

Common types of email misconfiguration include:

 

  • Lack of enforced TLS encryption: resulting in emails being transmitted in plaintext, rendering the patient data they contain readable by cybercriminals in the event of interception during transit.
  • Improper SPF/DKIM/DMARC setup: failure to configure or align these email authentication protocols correctly gives malicious actors greater latitude to successfully spoof trusted domains.
  • Disabled or lax user authentication: a lack of authentication measures, such as multi-factor authentication (MFA), increases the risk of unauthorized access and ePHI exposure.
  • Misconfigured secure email gateways: incorrect rules or filtering policies can allow phishing emails through or block legitimate messages.
  • Outdated or unsupported email client software: simply neglecting to download and apply the latest updates or patches from the email client’s vendor can leave vulnerabilities, which are well-known to cybercriminals, exposed to attack.

Social Engineering Attacks

A social engineering attack involves a malicious actor deceiving or convincing healthcare employees into granting unauthorized access or exposing patient data. Relying on psychological manipulation, social engineering attacks exploit a person’s trust, urgency, fear, or curiosity, and encompass an assortment of threats, including phishing and business email compromise (BEC) attacks, which are covered in greater depth below.

Phishing

As mentioned above, phishing is a type of social engineering attack, but they are so widespread that it warrants its own mention. Phishing sees malicious actors impersonating legitimate companies, or their employees, to trick victims into revealing sensitive patient data. 

Subsequently, healthcare organizations can be subjected to several different types of phishing attacks, which include:

 

  • General phishing: otherwise known as bulk phishing or simply ‘phishing’, these are broad, generic attacks where emails are sent to large numbers of recipients, impersonating trusted entities to steal credentials or deliver malware. 
  • Spear phishing: more targeted attacks that involve personalized phishing emails crafted for a specific healthcare organization or individual. These require more research on the part of malicious actors and typically use relevant insider details gleaned from their reconnaissance for additional credibility.
  • Whaling: a form of spear phishing that specifically targets healthcare executives or other high-level employees. 
  • Clone phishing:  when a cybercriminal duplicates a legitimate email that was previously received by the target, replacing links or attachments with malicious ones.
  • Credential phishing: also known as ‘pharming’, this involves emails that link to fake login pages designed to capture healthcare employees’ usernames and passwords under the guise of frequently used legitimate services.

Domain Impersonation and Spoofing

This category of threat revolves around making malicious messages appear legitimate, which can allow them to bypass basic email security checks. As alluded to above, these attacks exploit weaknesses in email client misconfigurations to trick the recipient, typically to expose and exfiltrate patient data, steal employee credentials, or distribute malware.

 

Domain spoofing email threats involve altering the “From” address in an email header to make it appear to be from a legitimate domain. If a healthcare organization fails to properly configure authentication protocols like SPF, DKIM, and DMARC, there’s a greater risk of their email servers failing to flag malicious messages and allowing them to land in users’ inboxes.

 

Domain impersonation, on the other hand, requires cybercriminals to register a domain that closely resembles a legitimate one. This may involve typosquatting, e.g., using “paypa1.com” instead of “paypal.com”. Alternatively, a hacker may utilize a homograph attack, which substitutes visually similar characters, e.g., from different character sets, such as Cyrillic. Malicious actors will then send emails from these fraudulent domains, which often have the ability to bypass basic email filters because they aren’t exact matches for blacklisted domains. Worse still, such emails can appear authentic to users, particularly if the attacker puts in the effort to accurately mimic the branding, formatting, and tone used by the legitimate entity they’re attempting to impersonate. 

Insider Email Threats

In addition to external parties, employees within a healthcare organization can pose email threats to the security of its PHI. On one hand, insider threats can be intentional, involving disgruntled employees or third-party personnel abusing their access privileges to steal or corrupt patient data. Alternatively, they could be the result of mere human error or negligence, stemming from ignorance, or even fatigue.

 

What’s more, insider threats have been exacerbated by the rise of remote and flexible conditions since the onset of the COVID-19 pandemic, which has created more complex IT infrastructures that are more difficult to manage and control.  

Business Email Compromise (BEC) Attacks

A BEC attack is a highly targeted type of social engineering attack in which cybercriminals gain access to, or copy, a legitimate email account to impersonate a known and trusted individual within an organization. BEC attacks typically require extensive research on the targeted healthcare company and rely less on malicious links or attachments, unlike phishing, which can make them difficult to detect.

 

Due to the high volume of emails transmitted within the healthcare industry, and the sensitive nature of PHI often included in communications to patients and between organizations, the healthcare industry is a consistent target of BEC attacks.

 

BEC attacks come in several forms, such as:

 

  • Account compromise: hijacking a real employee’s account and sending fraudulent messages.
  • Executive fraud: impersonating high-ranking personnel to request urgent financial transactions or access to sensitive data.
  • Invoice fraud: pretending to be a vendor asking for the payment of a fraudulent invoice into an account under their control.

Supply Chain Risk

Healthcare organizations increasingly rely on third-party vendors, including cloud service providers, software vendors, and billing or payment providers to serve their patients and customers. They constantly communicate with their supply chain partners via email, with some messages containing sensitive patient data; moreover, some of these organizations will have various levels of access to the PHI under their care.

 

Consequently, undetected vulnerabilities or lax security practices within your supply chain network could serve as entry points for email threats and malicious action. For instance, cybercriminals can compromise the email servers of a healthcare company’s third-party vendor or partner, and then send fraudulent emails from their domains to deploy malware or extract patient data.

 

Another, somewhat harrowing, way to understand supply chain risk is that while your organization may have a robust email security posture, in reality, it’s only as strong as that of your weakest third-party vendor’s security controls.

Email Deliverability

Why is High Email Deliverability Essential for Healthcare Companies?

With email communication playing a critical role in the customer engagement strategies of virtually every organization, high email deliverability rates are vital to success across all industries. In the healthcare sector, however, the stakes can be far higher. An undelivered email isn’t merely an inconvenience or a lost sales opportunity; it could mean a missed appointment, a delay in a prescription refill, or a failure to get a patient critical healthcare information. Or worse, the email could end up in the hands of an unintended recipient, including bad actors and cybercriminals.  

With this in mind, this post details why high email deliverability is essential for healthcare companies, as well as how your organization benefits from reliable and rapid email delivery. 

Speed and Efficiency

The primary reason that high email deliverability is crucially important to healthcare organizations is to best guarantee essential communications that directly impact an individual’s healthcare journey reach them promptly. These transactional emails can include appointment reminders, prescription renewals, product order confirmations, test results, explanation of benefits notices, payment reminders, and invoices. Administrative notifications related to software or systems that a patient might use, such as a password reset for an online portal, also fall under the category of transactional emails.

When transactional emails are delayed or fail to reach people altogether, they can compromise a patient’s ability to access care, adhere to treatment plans, stay informed on key facets of their healthcare journey, and, ultimately, achieve optimal health outcomes. 

When a patient fails to receive an expected email, such as a prescription confirmation, for example, it can leave them feeling confused and unsure of what to do next. For individuals who are sick, elderly, or managing chronic conditions, this can cause unnecessary stress, anxiety, and even compromise adherence to care plans.

In contrast, high email delivery rates create the opposite effect, helping patients get the communications and information they need. This increases their trust in your company and gives them a firmer sense of control over their healthcare journey. 

Compliance with HIPAA Regulations 

While the above point stresses the importance of reliable email delivery for the patient’s and customer’s benefit, healthcare companies also have a vested interest in ensuring communications reach the intended recipient for regulatory and patient privacy reasons.  

To comply with the Health Insurance Portability and Accountability Act (HIPAA), emails that contain sensitive patient data, i.e., electronic protected health information (ePHI), must be securely delivered to the intended recipient. If, on the other hand, a communication containing ePHI fails to reach the intended recipient patient, that represents a failure in secure communications and a potential HIPAA violation for your organization. 

After all, where did the patient’s data go? Was it delivered to the wrong person? Was it blocked by a spam filter and is left sitting unencrypted on a server somewhere?

If you can’t answer these questions, you could be exposed to a data breach, and it could result in a HIPAA violation, meaning your organization incurrs the associated consequences, including financial penalties and reputational damage. Conversely, deploying a fully HIPAA compliant email solution, such as LuxSci, supported by a dedicated infrastructure and designed for high email delivery enables your organization to include patient data in communications with confidence and ensure you messages land in the recipient’s inbox.  

Greater Levels of Personalization and Engagement

Finally, high email deliverability rates are essential for healthcare organizations because they help drive greater levels of engagement with patients and customers. Higher email deliverability means better inbox placement, leading to more emails being opened, more links being clicked, and more conversions for your communications and campaigns.

In the case of healthcare retailers, for example, this equates to converting more prospects into customers and, consequently, maximizing the ROI of email marketing campaigns, in some cases with up to 80% better results.  

While healthcare marketers, understandably, focus most of their efforts on crafting attention-grabbing headlines, personalizing the message content, and the email’s design elements, these factors are rendered irrelevant if the message fails to reach the recipient in the first place! When you take this into account, high email deliverability is a crucial component in optimizing the ROI of email communications and campaigns, and an all too often overlooked component at that.

HIPAA Compliant Email

Is There a HIPAA Compliant Email?

Yes, HIPAA compliant email is available through specialized platforms and services designed specifically for healthcare organizations that need to transmit protected health information securely. HIPAA compliant email solutions include encryption, access controls, audit logging, and other security features required to meet regulatory standards for protecting patient information during electronic communication. Healthcare providers, payers, and suppliers can choose from various HIPAA compliant email options that range from standalone secure messaging platforms to integrated solutions that work with existing healthcare systems. Understanding available HIPAA compliant email solutions helps organizations select appropriate tools for their communication needs while maintaining regulatory compliance and protecting patient privacy.

Types of HIPAA Compliant Email Solutions

Several categories of HIPAA compliant email solutions serve different organizational needs and technical requirements. Cloud-based secure email platforms provide hosted solutions that require minimal technical infrastructure while offering enterprise-grade security features. These platforms handle encryption, server maintenance, and security updates, allowing healthcare organizations to focus on patient care rather than email system management. On-premises HIPAA compliant email systems give organizations direct control over their email infrastructure and data storage locations. Hybrid solutions combine cloud convenience with on-premises control, allowing organizations to customize their email security approach based on specific requirements. Email encryption gateways work with existing email systems to add HIPAA compliance features without requiring complete system replacement.

Security Features in HIPAA Compliant Email Platforms

HIPAA compliant email platforms include end-to-end encryption that protects messages and attachments from unauthorized access during transmission and storage. Transport Layer Security protocols secure connections between email servers, while message-level encryption ensures that only intended recipients can read email content. Digital signatures verify sender authenticity and message integrity, preventing tampering or impersonation. Multi-factor authentication requires users to provide additional verification beyond passwords before accessing email accounts. Access controls limit which users can send emails to external recipients and which types of information can be included in different message categories. Automatic data loss prevention features scan outgoing emails for protected health information and apply appropriate security measures or block transmission of potentially sensitive content.

Business Associate Agreements and Vendor Requirements

Healthcare organizations using HIPAA compliant email services need business associate agreements with their email providers to ensure regulatory compliance. These agreements specify how email vendors will protect patient information, limit data use to authorized purposes, and report security incidents or unauthorized disclosures. Email providers operating as business associates must implement appropriate safeguards and allow healthcare organizations to audit their security practices. Vendor selection criteria should include security certifications, compliance track records, and technical capabilities that meet organizational requirements. Service level agreements define uptime expectations, support response times, and data recovery procedures. Due diligence processes help verify that email providers have appropriate security controls and compliance programs before entering into business relationships.

Implementation Challenges and Solutions

Healthcare organizations implementing HIPAA compliant email often encounter workflow disruptions as staff adapt to new security procedures and software interfaces. Training programs help users understand proper email security practices and organizational policies for handling protected health information. Change management strategies address resistance to new procedures and ensure that staff members understand the importance of email security compliance. Technical integration challenges arise when connecting HIPAA compliant email systems with existing healthcare applications and databases. Application programming interfaces enable custom integrations that streamline workflows while maintaining security standards. Migration planning addresses data transfer from legacy email systems and ensures that historical communications remain accessible when needed.

Cost Considerations for HIPAA Compliant Email

HIPAA compliant email solutions involve various cost components including software licensing, implementation services, ongoing support, and staff training expenses. Per-user subscription models allow organizations to scale email security based on their actual usage patterns. Enterprise licensing agreements may provide cost advantages for larger healthcare organizations with many email users. Hidden costs can include system integration expenses, data migration fees, and productivity losses during implementation periods. Return on investment calculations should consider potential savings from avoiding HIPAA violation penalties, reduced risk of data breaches, and improved operational efficiency from streamlined secure communication processes. Long-term cost analysis helps organizations budget appropriately for ongoing email security requirements.

Selecting the Right HIPAA Compliant Email Solution

Healthcare organizations should evaluate HIPAA compliant email options based on their specific communication patterns, technical infrastructure, and regulatory requirements. Feature comparisons help identify which platforms offer the security capabilities and integration options needed for particular use cases. Pilot testing allows organizations to evaluate user experience and system performance before making long-term commitments. Vendor demonstrations provide opportunities to assess ease of use, administrative features, and customer support quality. Reference checks with similar healthcare organizations offer insights into real-world performance and implementation experiences. Decision frameworks that consider security requirements, usability needs, and budget constraints help organizations select HIPAA compliant email solutions that will serve their long-term communication and compliance objectives effectively.

HIPAA Email API

What is a HIPAA Email API?

A HIPAA email API is a programming interface that allows healthcare applications to send secure emails containing protected health information while maintaining compliance with HIPAA regulations. These APIs provide developers with tools to integrate encrypted email functionality into healthcare software systems while automatically handling security requirements, audit logging, and PHI protection measures. Healthcare software development increasingly requires email capabilities for patient notifications, care coordination, and administrative communications. Standard email APIs lack the security controls and compliance features necessary for healthcare applications that handle sensitive patient data.

Technical Architecture and Security Framework

REST and SOAP protocols provide the foundation for most HIPAA email APIs, enabling healthcare applications to integrate email functionality through standard web service interfaces. These protocols support secure authentication and encrypted data transmission while maintaining compatibility with diverse healthcare technology environments. Message queuing systems help manage email delivery during high-volume periods while maintaining security controls throughout the transmission process. Healthcare applications can submit emails to secure queues where they receive encryption and compliance validation before delivery to recipients. Error handling mechanisms ensure that failed email transmissions do not compromise PHI security or leave sensitive data exposed in log files. HIPAA email APIs must provide detailed error information to developers while protecting patient information from unauthorized disclosure.

Authentication and Authorization Protocols

API key management provides secure access control for healthcare applications using email services. These keys must include appropriate permissions and expiration policies that prevent unauthorized access while enabling legitimate healthcare communications, allowing healthcare applications to authenticate users and obtain appropriate permissions for sending emails on their behalf. These protocols help ensure that only authorized personnel can trigger email communications containing PHI.

LuxSci supports three industry-standard authentication methods—alongside its proprietary LuxSci Secure option. These include:

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

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

Message Formatting, Template Management, and Security

MIME and S/MIME encoding support enables healthcare applications to send rich-text emails with attachments while maintaining encryption and security controls. These capabilities allow inclusion of medical images, test results, and formatted reports within compliant email communications. Template engines help healthcare developers create standardized email formats that include dynamic patient data while preventing inappropriate PHI disclosure. These systems can validate content against organizational policies before message transmission. Attachment handling procedures ensure that medical documents and images receive appropriate encryption and access controls when included in email communications. HIPAA email APIs must provide secure upload and transmission capabilities for healthcare file attachments.

Delivery Tracking and Status Reporting

Real-time delivery status updates help healthcare applications track email transmission progress and identify potential delivery issues. These status reports must provide actionable information without exposing PHI to unauthorized systems or personnel. Read receipt capabilities enable healthcare applications to confirm that recipients have accessed important medical communications. These features help care coordination while maintaining appropriate privacy protections for patient email interactions. Bounce management systems handle failed email deliveries appropriately while protecting PHI from exposure through error messages or automated responses. Healthcare applications need visibility into delivery problems without compromising patient privacy.

Compliance Logging and Audit Features

Automated audit trails capture detailed information about all email activities initiated through HIPAA email APIs. These logs must include sender identification, recipient information, transmission timestamps, and delivery status while protecting actual message content from unauthorized access. Compliance reporting features help healthcare organizations track their email usage patterns and identify potential policy violations. These reports can highlight unusual sending volumes, unauthorized recipient addresses, or messages that might violate PHI handling policies. Data retention controls ensure that API logs and message metadata comply with healthcare record-keeping requirements while managing storage costs and system performance. Healthcare organizations can configure retention periods based on their regulatory and operational needs.

Integration Patterns for Healthcare Applications

Electronic health record system (EHR), customer data platform (CDP), and Revenue Capture Management (RCM) platform integrations can enable automatic email messages and notifications to be sent based on clinical events like lab result availability or appointment scheduling changes. These integrations must respect minimum necessary standards while providing timely patient communications. Workflow automation allows healthcare applications to trigger email sequences based on patient care milestones or administrative requirements, tailoring communications based on user actions taken with each email. For example, healthcare organizations might send automated email reminders about upcoming appointments or medication refills. Batch processing capabilities enable healthcare organizations to send large volumes of patient communications efficiently while maintaining security controls and HIPAA compliance. These features support activities like appointment reminders, wellness newsletters, or billing notifications that affect many patients simultaneously.

Performance Optimization and Scalability

Rate limiting controls help healthcare organizations manage email volumes while preventing abuse or accidental bulk sending that might violate patient communication policies and damage your IP reputation. These controls can be customized based on organizational needs and user roles. Caching mechanisms improve API performance by storing frequently used templates and configuration data while maintaining appropriate security controls. These optimizations help reduce response times for healthcare applications without compromising PHI protection. Load balancing systems ensure reliable email delivery during peak usage periods when healthcare organizations send high volumes of patient communications. These systems must maintain security controls while distributing processing loads across multiple servers.

Testing and Development Support

Sandbox environments enable healthcare developers to test email functionality without exposing real patient data or sending communications to actual patients. These testing systems provide realistic API responses while using protected data that supports thorough integration testing. Documentation and code samples help healthcare development teams implement HIPAA email API functionality correctly while understanding security requirements and compliance obligations. These resources should include examples for common healthcare use cases and integration scenarios.

Finally, support services provide healthcare developers with technical assistance and compliance guidance during implementation and ongoing operations. API providers should offer expertise in both technical integration and healthcare regulatory requirements to ensure successful deployments.

HIPAA Compliant Email Marketing Software

Do You Need a VPN to Be HIPAA Compliant?

A VPN (Virtual Private Network) is not explicitly required by HIPAA regulations, but many healthcare organizations use VPNs as part of their security strategy to become HIPAA compliant. The HIPAA Security Rule requires appropriate protections for electronic protected health information without mandating particular technologies. VPNs help meet these requirements by encrypting data transmission, establishing secure remote access, and creating access controls that protect patient information from unauthorized disclosure.

HIPAA Network Protection Standards

The HIPAA Security Rule sets standards for protecting electronic health information without prescribing exact technical implementations. Healthcare organizations must implement safeguards that protect data integrity, confidentiality, and availability. Network protection measures matter when transmitting patient information across public networks. To become HIPAA Compliant, organizations must verify that transmitted information remains unaltered during transfer. Only authorized personnel should view sensitive data, regardless of whether access occurs within healthcare facilities or from remote locations. Many healthcare providers use VPNs to address these requirements, especially for staff working outside main facilities.

VPN Encryption Benefits

VPNs establish encrypted connections between devices and healthcare systems, creating protected pathways for data movement. When staff use public WiFi or home networks, this encryption prevents interception of patient information. Most VPN systems include authentication protocols that confirm user identity before granting system access. Access limitations can be configured to restrict which systems and information each user can view through VPN connections. Healthcare organizations often include VPN implementation details in their documentation during compliance audits or assessments, demonstrating how they protect data during transmission.

Securing Off-Site Healthcare Access

Medical professionals increasingly need access to patient records from various locations outside traditional facilities. Remote clinical work, telehealth appointments, and home-based administration all require secure handling of protected health information. Regardless of work location, HIPAA compliance demands consistent data protection standards. VPNs create secure connection tunnels that help maintain this protection across various networks and locations. For remote work to succeed, organizations develop clear guidelines about when VPN use becomes mandatory and how staff should establish secure connections. Mobile device management typically works alongside VPN protocols to ensure all endpoints meet security standards.

Exploring Security Alternatives

Healthcare organizations can meet HIPAA requirements without VPNs through several alternative approaches. Applications with built-in end-to-end encryption create secure channels for data transfer without full network encryption. Many cloud platforms designed for healthcare include sufficient authentication and security features for certain workflows. Some organizations implement zero trust architectures that verify every access request rather than relying on perimeter security. In practice, many healthcare systems use multiple security technologies rather than depending on any single solution. What matters for HIPAA compliance isn’t the technology chosen, but whether patient information remains properly protected throughout its lifecycle.

Technical VPN Deployment Factors

When implementing VPNs for healthcare environments, several technical elements require attention. Encryption must meet current standards like AES-256 to adequately protect healthcare data. Authentication should involve multiple verification factors beyond passwords alone. Usage monitoring helps identify unusual patterns that might indicate security problems. Staff need training on correct VPN procedures and potential security risks. IT support must address connection difficulties promptly, as frustrated users might otherwise bypass security measures. How these elements work together determines whether VPN deployment strengthens or weakens overall security posture.

Compliance Documentation Practices

HIPAA requires thorough documentation of all security measures and risk evaluations. Security policies should describe VPN usage requirements, configuration standards, and monitoring practices. System architecture documentation must show how VPN connections fit within the overall network design. Regular risk assessment examines potential vulnerabilities in VPN implementations. Response plans outline steps to address potential VPN security incidents. Well-organized documentation helps organizations demonstrate reasonable security efforts during regulatory reviews. During audits or investigations, clear records of security implementation decisions provide evidence of due diligence in protecting patient information

HIPAA Compliant

Is Microsoft Forms HIPAA Compliant?

Microsoft Forms is considered HIPAA compliant only when properly configured within a Microsoft 365 Enterprise or Business environment with an executed Business Associate Agreement (BAA). Unlike various competing products, Microsoft includes Forms among its covered services in its BAA, allowing healthcare organizations to collect protected health information when implemented with proper security controls and organizational policies.

Microsoft Business Associate Agreement Coverage

Microsoft offers a BAA that covers Microsoft Forms when used within a properly licensed Microsoft 365 environment. This agreement establishes Microsoft as a business associate under HIPAA regulations and defines responsibilities for protecting healthcare information. The BAA covers Microsoft Forms along with other Microsoft 365 services such as Exchange Online, SharePoint Online, and Teams. Healthcare organizations must execute this agreement before using Microsoft Forms to collect protected health information. The BAA establishes contractual protections beyond standard terms of service and the requirements of becoming HIPAA compliant.

Required Configuration for HIPAA Compliance

Making Microsoft Forms HIPAA compliant requires specific configuration beyond simply signing a BAA. Organizations must implement appropriate access controls using Microsoft 365 administrative settings to restrict form creation and data access to authorized personnel. Enabling audit logging through the Microsoft 365 Compliance Center helps track who creates, modifies, and accesses form data. Organizations need to configure retention policies that align with HIPAA record-keeping requirements. Multi-factor authentication adds an essential security layer for employees accessing protected health information. These technical controls work together to create a compliant environment for collecting patient information.

Security Features in Microsoft Forms

Microsoft Forms includes several security capabilities that support HIPAA compliance requirements. The platform encrypts data both during transmission and storage within Microsoft’s infrastructure. Access controls integrate with Microsoft 365 identity management to restrict form data visibility. Audit capabilities track form creation, modification, and response activities. Microsoft’s cloud infrastructure meets various compliance certifications beyond HIPAA, including FedRAMP, ISO 27001, and SOC standards. These underlying security measures provide the technical foundation for compliant form implementation when properly configured.

Limitations and Compliance Considerations

While Microsoft Forms can be HIPAA compliant, certain limitations require attention from healthcare organizations. The standard form templates do not include healthcare-specific authorization language required by the HIPAA Privacy Rule. Organizations must customize forms to include appropriate patient consent statements and privacy notices. Certain advanced features like form branching may create complexity in tracking what information appears to which respondents. Organizations need policies governing form creation and approval to ensure all necessary compliance elements appear consistently. These limitations require procedural controls beyond technical configuration.

Implementation Best Practices

Healthcare organizations implementing Microsoft Forms for collecting protected health information can benefit from following established best practices. Creating standardized form templates with pre-approved compliance language helps maintain consistency. Limiting form creation permissions to trained staff members reduces compliance risks. Regular privacy and security training for all employees who handle form data improves organizational awareness. Conducting periodic audits of form content and access patterns identifies potential compliance issues. Integrating forms with secure document storage in SharePoint improves information governance. These practices can enhance the security of patient information collected through electronic forms.

Alternative Form Solutions and Considerations

Microsoft Forms can be considered HIPAA compliant, but organizations should evaluate whether it provides the optimal solution for their needs. Specialized healthcare form platforms may offer additional features like electronic signature capture, direct EHR or CDP integration, or healthcare-specific templates. Microsoft Forms works best for organizations already invested in the Microsoft 365 ecosystem who need integrated form capabilities. The decision between Microsoft Forms and alternatives like LuxSci depends on factors including existing technology investments, integration requirements, complexity of form needs, and organizational resources for configuration and maintenance.

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:

  1. Computer A connects to Computer B (no security)
  2. Computer B says “Hello” (no security)
  3. Computer A says, “Let’s talk securely over TLS” (no security)
  4. Computers A and B agree on how to do this (secure)
  5. 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:

  1. purchase SSL certificates
  2. configure the email servers to use them (and keep these configurations updated)
  3. 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:

  1. No TLS: never use it.
  2. Opportunistic TLS: use it if available; if not, send it insecurely.
  3. 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:

  1. The recipient’s servers support TLS for outbound email (there is no way to test this externally).
  2. The mail servers (where the “From” or “Reply” email address is hosted) support TLS for inbound email.
  3. 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:

  1. 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.
  2. 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:

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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).
  6. 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.
  7. 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.
  8. 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.
