Paubox
HIPAA-compliant email that requires no portal or extra steps
About Paubox
Paubox is a HIPAA-compliant email encryption service designed specifically for healthcare. Unlike traditional secure email, Paubox encrypts every outbound message by default and delivers it directly to the recipient's inbox — no logins, portals, or password prompts. It signs a Business Associate Agreement (BAA) with all customers and integrates seamlessly with Google Workspace and Microsoft 365 so practices can keep their existing email while adding HIPAA compliance, inbound threat protection, and data loss prevention.
