Send Secure Emails: Alternatives to Web Portals

Digital technologies have entirely shifted how individuals want to interact with their healthcare providers. As consumers have become used to emailing or texting with their hairstylists, mechanics, and other providers to schedule appointments, they want to have the same level of interaction with their healthcare providers.

However, many healthcare organizations find it challenging to deliver the same experience because of their compliance requirements under HIPAA. They must balance usability and access with security and patient privacy. To send secure emails, they often resort to secure web portals.

Problems with Secure Web Portals

One of the most common ways that healthcare organizations communicate securely with patients is by using the secure web portal method of email encryption. In this scenario, messages are sent to a secure web server, and a notification is sent to the recipient, who then logs into the portal to retrieve the message.

While highly secure, this method is not popular with recipients because of the friction it creates.

To maintain a high level of security, users must log in to a separate account to retrieve the message. This extra step creates a barrier, especially for individuals who are not tech-savvy. In addition to creating a new account, they must remember a different username and password to access their secure messages. If the recipient doesn’t have this information readily available, they will likely delete the message and move on with their day. Many users will never bother logging in because of the inconvenience. This creates issues for organizations that want to use email for standard business communications and patient engagement efforts. 

While this method may be appropriate for sending highly sensitive information like medical records, financial documents, and other valuable information, many emails that must meet compliance requirements only infer sensitive information and do not require such a high level of security. Flu shot reminder emails are not as sensitive or potentially devastating as sending the wrong medical file to someone. Healthcare organizations need to use secure email solutions that are flexible enough to send only the most sensitive emails to the portal and less sensitive emails using other methods.

How to Meet Compliance Requirements for Sending Secure Email

So, what other options do you have for sending secure emails? The answer will depend on what specific requirements you need to meet. Healthcare organizations that must abide by HIPAA regulations will find a lot of flexibility regarding the technologies they can use to protect ePHI in transit.

In addition to a secure web portal, three other types of encryption are suitable for email sending: TLS, PGP, and S/MIME. PGP and S/MIME are more secure than a web portal. They also require advanced technological skills and coordination with the end-user to implement, which makes them impractical for most business email sending.

That leaves us with TLS, which is suitable to meet most compliance standards (including HIPAA) and delivers an email experience much like that of a “regular” email.

Send Secure Emails with TLS Encryption

TLS encryption is an excellent option for secure email sending that provides a seamless experience for the recipient. Emails sent securely with TLS appear like regular, unencrypted emails in the recipient’s inbox.

TLS encrypts the message contents as they travel between mail servers to prevent interception and eavesdropping. Once the message reaches the inbox, it is unencrypted and can be read by anyone with access to the email account. For this reason, it is less secure than a portal but secure enough to meet compliance requirements like HIPAA.

If you’re wondering why this is, HIPAA only requires covered entities and business associates to protect PHI when it is stored on their systems or as it is transmitted elsewhere. After the message reaches the recipient, it is up to the recipient to decide what they want to do to secure the information. HIPAA does not apply to individuals. Each person is entitled to share and store their health information however they see fit.

Conclusion

Balancing security and usability is a significant challenge for healthcare organizations. If the message is too secure, it may be difficult for the recipient to open and engage with it. If it’s not secure enough, it is too easy for cybercriminals and other bad actors to intercept private information as it is sent across the internet. 

Choosing an email provider like LuxSci, which offers flexible email encryption options, allows users to choose the right level of encryption for each message to maximize engagement and improve health outcomes. Contact our team today to learn more about how we can support your efforts.

HIPAA Compliant Email

Here’s What HIPAA Compliant Email Salespeople Don’t Tell You

With email security threats continuously increasing in number and sophistication, as well as healthcare companies requiring secure solutions to communicate with patients and customers, the need for HIPAA compliant email solutions has never been greater. 

However, when looking for the right secure email services provider (ESP), healthcare organizations run the risk of making inaccurate assumptions about HIPAA compliance via what they learn from prospective vendors. This is due to the tendency for sales materials for HIPAA compliant email services, such as web pages or promotional videos, to highlight the strengths of the platform, while downplaying a healthcare company’s own role and responsibilities in securing protected health information (PHI). 

With this firmly in mind, here are six key things that HIPAA compliant email salespeople don’t tell you about securing communications and achieving compliance. 

1. The Shared Responsibility Model

Firstly, HIPAA compliant email salespeople are unlikely to emphasize the idea of shared responsibility when it comes to data security. This is the idea that two entities that share access to data, e.g., a healthcare company and their ESP, have a shared responsibility to preserve the privacy of that data.

In reality, most sales pitches explain the benefits and features of the solution, as opposed to stressing that compliance truly depends on how it’s configured and used. Now, that’s not to say that a salesperson is trying to hide this fact, as they’ll probably allude to training and configuration requirements. But, they’ll be less likely to make light of this and, more broadly, how shared responsibility factors into compliance.

2. A BAA Doesn’t Automatically Make You HIPAA Compliant

A business associate agreement (BAA) is essential for HIPAA compliance, but signing one doesn’t automatically make you compliant. Your organization still has to use the email delivery solution in a way that aligns with HIPAA regulations, which involves proper configuration, training, oversight, and reporting.

The misconception among some healthcare companies that a BAA equals compliance may be perpetuated by the term “HIPAA compliant email services provider”.  This could give some the impression that the vendor is fully HIPAA compliant and, subsequently, in signing a BAA with them, the use of their services is fully compliant.

But, it’s not that simple.

Simply signing a BAA obscures the real effort involved in achieving compliance. There’s no official HIPAA seal of approval, and HIPAA compliant means that the solution is capable of being configured for compliant use, which is a shared responsibility. HIPAA compliant email salespeople are unlikely to volunteer this nuance, especially if their email solution requires considerable configuration or has a steep learning curve to use it securely.

3. Not All Solutions or Features Are HIPAA Compliant

Another key detail often underplayed by vendor sales materials of HIPAA compliant email solutions is that some of their features, or even entire services, aren’t covered by their BAAs, so they can’t be used to handle PHI. 

These tools are referred to as “out of scope” and may include tools capable of integration with the email service, such as analytics or AI capabilities, but they don’t possess the cyber risk mitigation measures that align with HIPAA regulations. Perhaps the main reason for this is that many mass-market email delivery solutions, such as Microsoft 365 or Google Workspace, are designed for companies across all sectors. Consequently, while they can be HIPAA compliant, they weren’t developed from the ground up with the stringent regulatory demands of the healthcare industry in mind.

4. Solutions Are Not HIPAA Compliant “Out of The Box”

HIPAA compliant email salespeople may suggest that compliance is built into their platform, and healthcare organizations can use it to transmit PHI straight away, but this isn’t the case. Healthcare companies must still configure the email platform accordingly, as per the security requirements determined by their risk assessment, e.g., applying the right level of encryption. 

Also, if the email service is difficult to configure for HIPAA compliance or if the vendor’s configuration documentation lacks detail, that presents another obstacle to its compliant use. 

In addition to configuration, healthcare companies also have to implement access management controls and policies, establishing the extent to which each employee can access PHI in respect to their roles and responsibilities. From there, they will have to train their workforce on how to use the HIPAA compliant email solution securely, which may include those tools that fall outside the scope of your BAA with the vendor, and must not be used for the disclosure of patient data.

5. Essential Security Features Cost Extra 

Another more egregious version of an ESP not being HIPAA compliant out of the box is having features required for compliance, such as encryption or audit logging, as premium add-ons and not included in the solution’s base pricing. 

A vendor’s sales materials for its email service might list the necessary safeguards, but underemphasize the fact that only some versions of their platform are truly HIPAA compliant. Consequently, healthcare companies must confirm that the features required for HIPAA compliant email communications are included in the plan they’re purchasing. 

6. The Importance of Staff Training on HIPAA

HIPAA compliant email salespeople are often remiss in stressing the need for additional workforce training alongside the deployment of their platform. A healthcare company’s employees must be trained on how to securely use the email client, how to ID potential threats, and best practices for including PHI in email communications, as well as the regulations tied to HIPAA and data security.

This includes educating users on the differences between regular and secure email, and what they must do to safeguard patient and customer data. Fortunately, secure email solutions from providers like LuxSci enable automated email encryption, and users do not need to take any additional actions to ensure encryption when sending emails.

Additionally, in some cases, employees will need to be trained on which tools or features do not align with HIPAA guidelines and must not be used to process PHI.

HIPAA Emailing Patient Information

What is a HIPAA Compliant Email Service?

A HIPAA compliant email service is a secure email platform that meets all Health Insurance Portability and Accountability Act requirements for protecting patient health information during electronic communications. These specialized email platforms implement administrative, physical, and technical safeguards required under the HIPAA Security Rule, enabling healthcare providers, business associates, and covered entities to transmit protected health information electronically without violating federal privacy regulations. Unlike standard email services that lack encryption and access controls, a HIPAA compliant email service incorporates end-to-end encryption, audit logging, user authentication protocols, and business associate agreements to ensure that all electronic communications containing individually identifiable health information remain secure throughout transmission and storage.

Why a HIPAA Compliant Email Service is Necessary

Healthcare organizations that handle protected health information must comply with stringent regulatory requirements when using electronic communication systems. The HIPAA Security Rule mandates that covered entities implement appropriate administrative, physical, and operational safeguards to protect the confidentiality, integrity, and availability of electronic protected health information. When healthcare providers use email to communicate about patients, discuss treatment plans, or transmit medical records, these communications become subject to HIPAA regulations because they contain individually identifiable health information. Standard consumer email services like Gmail, Yahoo, or Outlook do not provide the necessary security controls required for healthcare communications, creating potential compliance violations that can result in substantial penalties from the Office for Civil Rights.

A HIPAA compliant email service handles these regulatory challenges by implementing encryption protocols, access controls, and audit mechanisms required under federal law. These specialized platforms ensure that all email communications are encrypted both in transit and at rest, preventing unauthorized access to protected health information even if messages are intercepted during transmission. Healthcare organizations using a HIPAA compliant email service can establish proper business associate agreements with their email provider, creating the legal framework required for third-party handling of protected health information.

Safeguards in Healthcare Email Systems

The administrative safeguards required for a HIPAA compliant email service involves policies, procedures, and controls governing how healthcare organizations manage email communications containing protected health information. Healthcare entities implementing secure email systems need to establish clear protocols for user access management, ensuring that only authorized workforce members can send, receive, or access emails containing patient information. These administrative controls include implementing role-based access permissions, establishing procedures for granting and revoking email access when employees join or leave the organization, and maintaining detailed documentation of all email-related policies and training programs.

Workforce training is another important aspect of safeguards for healthcare email communications. Organizations using a HIPAA compliant email service need to educate their staff about proper email usage, including guidelines for when it is appropriate to include protected health information in electronic communications, how to properly send secure emails, and procedures for reporting potential security incidents or unauthorized access attempts. This training ensures that healthcare workers understand their responsibilities when using secure email systems and helps prevent inadvertent disclosure of protected health information through improper email practices. Refresher training and updates to email policies help maintain compliance as technology and regulations evolve, while documented training records provide evidence of organizational commitment to protecting patient privacy.

Encryption Standards

Operational safeguards are the core of any HIPAA compliant email service, delivering the security controls necessary to protect electronic protected health information during transmission and storage. End-to-end encryption represents the most important technical safeguard, ensuring that email messages containing patient information are encrypted using strong cryptographic algorithms before transmission and can only be decrypted by authorized recipients. Modern secure email platforms implement Advanced Encryption Standard (AES) with 256-bit keys or similar encryption methods that meet current industry standards for protecting sensitive healthcare data. This encryption protects against unauthorized interception of email communications, even if messages are captured while traveling across public internet networks.

Access control mechanisms within a HIPAA compliant email service prevent unauthorized users from accessing protected health information stored in email systems. Multi-factor authentication requirements ensure that users must provide multiple forms of verification before accessing their secure email accounts, adding additional protection beyond simple username and password combinations. Automated audit logging captures detailed records of all email activities, including message sending and receiving times, user login attempts, and any administrative actions performed within the system. These audit logs provide healthcare organizations with the documentation necessary to demonstrate compliance during regulatory audits while also enabling detection of potential security incidents or unauthorized access attempts.

Digital certificates and secure email gateways provide additional technical safeguards by verifying the identity of email senders and recipients while ensuring that messages can only be transmitted between properly authenticated parties. Message integrity controls detect any unauthorized modifications to email content during transmission, while secure backup and disaster recovery systems protect against data loss while maintaining encryption standards for stored communications.

Physical Safeguards for Email Infrastructure

Physical safeguards protect the computer systems, workstations, and electronic media used to store and process emails containing protected health information. A HIPAA compliant email service provider maintains secure data centers with appropriate physical access controls, environmental protections, and equipment safeguards to prevent unauthorized access to servers hosting healthcare communications. These data centers implement multiple layers of physical security, including biometric access controls, security cameras, environmental monitoring systems, and redundant power supplies to ensure continuous protection of stored email data.

Healthcare organizations using secure email services also need to implement appropriate physical safeguards at their own facilities. Workstations used to access a HIPAA compliant email service need proper positioning to prevent unauthorized viewing of email content, automatic screen locks when users step away from their computers, and secure disposal procedures for any printed email communications containing protected health information. Mobile devices accessing secure email systems require additional protection through device encryption, remote wipe capabilities, and secure container technologies that separate healthcare communications from personal data on employee smartphones or tablets.

Environmental controls within healthcare facilities help protect against physical threats to email security, including proper climate control for computer equipment, fire suppression systems that won’t damage electronic devices, and backup power systems to maintain email availability during emergencies. Regular maintenance and monitoring of physical infrastructure ensure that protective measures remain effective while documentation of physical safeguards provides evidence of organizational commitment to protecting patient information stored in electronic communications.

Business Associate Agreements & Vendor Management

Healthcare organizations selecting a HIPAA compliant email service need to establish proper business associate agreements that define the legal responsibilities and obligations of both parties regarding protected health information. These agreements specify how the email service provider will protect patient data, what uses and disclosures are permitted, how security incidents will be reported, and what happens to protected health information when the business relationship ends. A comprehensive business associate agreement for email services addresses encryption requirements, audit logging standards, employee training obligations for the service provider, and procedures for responding to regulatory inquiries or patient requests for information.

Vendor due diligence processes help healthcare organizations evaluate potential email service providers to ensure they can meet HIPAA compliance requirements. This evaluation includes reviewing the provider’s security certifications, examining their data center facilities and security controls, assessing their incident response capabilities, and verifying their experience with healthcare industry regulations. Ongoing vendor management activities include regular security assessments, review of audit reports and compliance documentation, monitoring of service level agreements, and periodic evaluation of the email provider’s ability to adapt to changing regulatory requirements.

Healthcare organizations also need to consider the geographic location of email servers and data processing facilities when selecting a HIPAA compliant email service provider. Some providers offer options for maintaining all protected health information within United States borders, while others may provide additional privacy protections through international data processing agreements. Contract negotiations address liability allocation, insurance requirements, termination procedures, and dispute resolution mechanisms to protect healthcare organizations from potential compliance violations or security incidents related to their email communications.

Implementation and Migration

Healthcare organizations transitioning to a HIPAA compliant email service need careful planning to ensure seamless migration while maintaining security throughout the process. Implementation strategies address user training requirements, data migration procedures, integration with existing healthcare information systems, and testing protocols to verify proper security controls before going live with the new email system. Organizations need to develop detailed project timelines that account for user adoption challenges, potential technical issues, and regulatory compliance verification activities while minimizing disruption to patient care activities.

Migration planning includes inventory of existing email communications containing protected health information, assessment of integration requirements with electronic health record systems and practice management software, and development of backup procedures to protect against data loss during the transition process. Healthcare organizations need to coordinate with their chosen email service provider to establish proper configuration settings, implement appropriate security controls, and conduct thorough testing of encryption, access controls, and audit logging capabilities. User acceptance testing ensures that healthcare workers can effectively use the new secure email system while maintaining productivity and patient care quality.

Post-implementation activities include monitoring of email security controls, regular review of audit logs and compliance reports, periodic security assessments to identify potential vulnerabilities, and continuous training programs to help users adapt to new email features and security requirements. Healthcare organizations benefit from establishing internal email governance committees that oversee compliance activities, evaluate new email features or capabilities, and coordinate responses to security incidents or regulatory changes affecting electronic communications.

How to Secure SMTP Email Delivery with TLS

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.

What Are the Most Effective Patient Engagement Solutions?

The most effective patient engagement solutions make healthcare communication clear, convenient, and secure. Strong solutions create a link between clinical teams and patients through technology that supports real conversations, reliable scheduling, and accurate follow-up. By blending data security with ease of use, these systems turn daily interactions into continuous care, helping both sides stay informed and connected under the structure of HIPAA compliance.

The growth of patient engagement solutions in healthcare

Patient engagement solutions have become imperative as healthcare moves towards collaboration and prevention. Instead of relying on phone calls or mailed reminders, providers can now reach patients instantly through encrypted portals or mobile applications. These systems allow individuals to confirm appointments, receive reminders, and access their health records whenever they need to. Patients who understand their conditions and have consistent access to care details are far less likely to miss appointments or misunderstand instructions. Clinics benefit from fewer administrative delays and more accurate information, which improves care coordination across departments.

Every reliable system combines several elements including security, usability, education, and integration. The interface should be simple enough for patients of any age to navigate without assistance. Real-time scheduling and message delivery ensure that staff can respond quickly and keep patients informed. Built-in educational libraries allow organizations to distribute accurate, plain-language information without creating separate resources. Integration with electronic health records reduces duplicate data entry and ensures that every message, test result, or treatment note appears in the same system. These features, when implemented together, make engagement a natural part of daily care instead of an additional task.

Security and compliance

Digital communication in healthcare cannot exist without strong privacy controls. Encryption keeps information unreadable to outsiders, while verified identity checks confirm that only authorized users can access messages or files. The vendor’s Business Associate Agreement sets the legal framework for how data is stored, shared, and removed. Providers should ensure that their patient engagement solutions meet the technical safeguards listed in 45 CFR 164.312 and maintain proof through independent security audits. These measures reassure patients that their information is handled with discretion and reinforce the provider’s reputation for professionalism and reliability.

Fitting technology naturally into daily workflows

The most successful systems are the ones that blend quietly into a clinic’s existing routine. Staff should not have to juggle separate platforms or repeat entries in different databases. Integration allows appointment confirmations, billing updates, and patient messages to appear instantly in one dashboard. Simple automation such as digital intake forms or reminder messages can save hours of administrative time each week. When technology works with staff rather than against them, it lightens the load on clinical teams and creates a smoother experience for patients from arrival to discharge.

Communication and education to drive participation

Education lies at the heart of engagement. A patient who understands their diagnosis or treatment plan is far more likely to stay involved. Good communication tools make that education interactive rather than static. Secure messaging gives patients the confidence to ask questions at their own pace. Providers can respond with tailored advice or share learning materials that match the patient’s literacy level or condition. These exchanges create a continuous learning environment where information flows both ways, fostering accountability and reducing unnecessary clinic visits.

Using data to improve engagement outcomes

Data generated by digital communication reveals trends that would otherwise remain hidden. By reviewing message response rates, appointment attendance, and satisfaction surveys, healthcare organizations can see what truly improves patient involvement. Patterns in this information might show that certain types of reminders work better for older patients or that specific message timing encourages faster replies. Patient engagement solutions that present this data clearly help administrators refine strategies without speculation.

Engagement technology must serve the people delivering care, as well as patients. Simple dashboards and logical task views keep workloads organized. Automation handles repetitive actions such as distributing follow-up surveys or confirming prescription refills. The result is less time spent on manual tracking and fewer communication errors between departments. Clinicians can dedicate more attention to complex cases, confident that routine communication continues in the background. When staff find the platform easy to use, adoption spreads naturally, and compliance becomes effortless rather than forced.

Choosing patient engagement solutions

Selecting the right system involves balancing capability, reliability, and growth potential. A small clinic may prioritize affordability and essential communication tools, while larger networks might need analytics, multilingual interfaces, and remote monitoring. Testing through a limited rollout helps verify usability and security before full adoption. Strong vendor partnerships matter as much as technology itself; providers should expect consistent updates, accessible support, and transparent pricing. Systems that evolve alongside clinical needs avoid obsolescence and remain valuable for many years.

Effective engagement tools change the rhythm of care by making communication an ongoing process instead of a single event. Patients gain clarity and confidence in managing their health, and providers gain insight into how treatment is followed outside the clinic. Over time, this creates a culture of collaboration built on information and trust. Patient engagement solutions that combine usability, privacy, and empathy improve not only outcomes but also the daily experience of healthcare for everyone involved.
