Executed Business Associate Agreement (BAA): A provider MUST sign a legally binding BAA. Without a signed BAA, any claim of HIPAA compliance is legally invalid under U.S. Department of Health and Human Services (HHS) regulations.
End-to-End Encryption: The platform must employ AES 256-bit encryption for data stored at rest and TLS 1.2 or higher for data transmitted over the internet.
Strict Access & Audit Logs: System administrators must have access to activity logs detailing who sent, viewed, downloaded, or deleted faxes containing Protected Health Information (PHI).
Automatic Log-Off & Authentication: Mobile and web interfaces must implement multi-factor authentication (MFA) and auto-logout protocols to prevent unauthorized physical access.
