Full Review

Paubox solves one of the most persistent headaches in healthcare communication: sending HIPAA-compliant email without forcing recipients to log into a portal or enter a password. Traditional secure email solutions work by sending recipients a notification that a secure message is waiting, then requiring them to visit a portal and authenticate. Patients hate this process, and the result is that many practices either avoid email entirely or, worse, send unencrypted messages containing protected health information.

Paubox takes a fundamentally different approach. Every outgoing email is automatically encrypted using TLS, and recipients read the message directly in their normal email inbox. There is no portal, no password, no extra step. The encryption happens behind the scenes, completely transparently. For the sender, nothing changes about their email workflow. For the recipient, the message looks and behaves like a normal email. This is how healthcare email should have worked from the beginning.

The inbound security features add additional value. Paubox scans incoming email for phishing attempts, malware, and suspicious links before they reach your staff's inbox. For small practices, where a single clicked phishing link can lead to a devastating ransomware attack, this protective layer is worth the subscription cost on its own.

Paubox integrates with Google Workspace and Microsoft 365, so you keep your existing email infrastructure. Setup is straightforward, typically completed in under an hour, and requires no technical expertise. The per-user pricing is clear and predictable.

The limitation is scope. Paubox addresses email security, but it does not cover the broader cybersecurity posture of your practice. You still need to worry about endpoint security, network protection, staff training, access controls, and the many other elements of a comprehensive HIPAA compliance program. Paubox is one piece of the puzzle, not the whole picture. But it is an important piece, and it solves the email encryption problem more elegantly than any other solution we have evaluated.
