In March 2023, a healthcare provider’s email account was compromised in a phishing attack that exposed fewer than 2,000 records. In the context of healthcare breaches, that’s a small incident. The OCR enforcement that followed wasn’t driven by the breach size. It was driven by the absence of a Security Risk Analysis. The fine was $103,000. The investigation ran for years.
Email is where a significant portion of dental practice HIPAA exposure actually lives, and it’s where most practices make assumptions that don’t hold up under scrutiny. Standard Gmail and Outlook aren’t HIPAA-compliant by default. Using them to send treatment plans, referral information, X-ray attachments, or insurance documentation without proper encryption is a violation regardless of whether anyone intercepts the message.
Choosing the right email encryption approach for your dental office comes down to understanding what HIPAA actually requires, what the options are, and what the practical trade-offs look like for a clinical environment. If you’re not sure where your practice stands, our dental IT services and support team can walk you through it.
The HIPAA Security Rule requires dental practices to protect ePHI in transit. For email, that means implementing transmission security that prevents unauthorized access to messages containing patient information. The specific mechanism HIPAA mandates is encryption, though it provides flexibility in implementation approach.
A nuance worth knowing: the ADA has noted that HIPAA doesn’t technically prohibit sending unencrypted email containing PHI, provided the practice includes email in its Security Risk Analysis, maintains reasonable safeguards, sends breach notification if unencrypted PHI is compromised, and honors patient requests for unencrypted communication. In practice, unencrypted email containing PHI is considered a compliance risk that most advisors recommend against.
What’s non-negotiable: any cloud email provider that stores or processes PHI on your behalf requires a Business Associate Agreement (BAA). Standard Gmail and Microsoft 365 consumer accounts do not come with BAAs. Google Workspace and Microsoft 365 Business plans can provide BAAs, but proper configuration is still required.
Most modern email platforms use Transport Layer Security (TLS) to protect messages in transit between mail servers. TLS is a baseline protection that works when both sending and receiving servers support it. The problem is that it doesn’t protect the message once it arrives in the recipient’s inbox, and it depends on both sides of the transmission having compatible TLS configurations.
End-to-end encryption (E2EE) keeps a message encrypted from the moment it leaves the sender until the recipient decrypts it, including during storage. S/MIME and PGP are the two standard E2EE protocols for email. Both require setup on both ends, which creates practical friction in clinical environments where staff are sending referrals to specialists who may not have compatible configurations.
A third approach, secure messaging portals, avoids the friction of E2EE by keeping the message off standard email entirely. The sender composes the message in a secure portal, the recipient gets a notification with a link, and they authenticate to view the content in the portal rather than in their inbox. No compatibility requirement on the recipient side.
For practices already on Microsoft 365 Business Premium or higher, Microsoft Purview Information Protection provides built-in message encryption that works without additional software. Messages containing PHI can be automatically or manually encrypted, recipients access them through a secure portal link if they don’t have a compatible Microsoft account, and the BAA is available through Microsoft’s enterprise agreements. This is often the lowest-friction path for practices already in the Microsoft ecosystem.
Paubox integrates directly with Google Workspace and Microsoft 365, encrypting messages automatically without requiring any action from staff or recipients. Messages arrive in the recipient’s standard inbox, decrypted automatically if the transmission pathway is secure, or delivered via a portal link if not. It provides a BAA and is built specifically for healthcare compliance. For practices where staff adoption is a concern, the lack of extra steps makes Paubox one of the more practical options.
Virtru sits on top of existing email platforms as an add-on, adding end-to-end encryption to Gmail and Microsoft email without requiring a platform switch. Staff send messages normally through their existing interface and toggle encryption on for messages containing PHI. Recipients can access encrypted messages through a browser viewer without installing software. Virtru provides BAAs for both the Virtru service and supports proper configuration of the underlying Google or Microsoft platform. Pricing starts at $119 per month for the Starter plan, which covers up to 5 users.
LuxSci is a complete HIPAA-compliant email platform rather than an add-on to an existing service. It handles hosting, encryption, archiving, and compliance documentation in a single service, and has been used by medical and dental organizations since 1999. It’s a stronger fit for practices that want a purpose-built HIPAA email environment rather than layering compliance tools onto a consumer platform. Pricing for their mid-sized healthcare tier starts at $99 per month, with enterprise plans available by quote.
MailHippo is designed specifically for dental and orthodontic practices. It uses AES 256-bit encryption, and on the Pro plan supports attachments up to 100MB per message — useful for X-ray files and imaging attachments. (The Basic plan supports attachments up to 50MB.) It allows recipients to send encrypted replies even if they don’t have a MailHippo account. It works alongside existing email providers and is positioned as an accessible entry point for practices that haven’t previously implemented any encryption solution.
Across options, the criteria that matter most for dental practices:
A 2026 Paubox survey of 170 U.S. healthcare IT leaders found that 100% rated their real-time breach detection as excellent or good — yet 58% admitted their organization had been breached through email in the past two years. The gap between perceived and actual compliance is consistent across dental IT environments.
The most common configuration failures NOVA encounters:
The proposed 2025 HIPAA Security Rule updates would make many currently “addressable” safeguards fully required. Email encryption and access controls are both in that category. Practices that haven’t addressed them are accumulating compliance risk as the regulatory environment tightens.
