FAQ

Is Google fax HIPAA compliant?

Google Workspace alone does not offer native fax functionality, though it can be HIPAA compliant for email storage if a BAA is signed. To send HIPAA-compliant faxes via Google, you must integrate a compliant third-party online fax service (like Fax.Plus or iFax) that executes a BAA to handle fax transmissions securely.

What is the safest free online fax service?

For verified U.S. medical professionals, Doximity DocFax is the safest free HIPAA-compliant fax service. While general web services like FaxZero offer basic free faxing, they lack signed BAAs and robust security protocols required by federal healthcare regulations, making them unsafe for transmitting protected health information (PHI).

Which eFax is HIPAA compliant?

Only eFax Protect (and eFax Corporate plans) is HIPAA compliant. Standard consumer tiers like eFax Plus and eFax Pro do not include a signed Business Associate Agreement (BAA) or guaranteed technical safeguards required under federal law to protect patient medical records.

Which is better, eFax or MyFax?

eFax is better suited for medical providers because it offers a dedicated, HIPAA-compliant tier (eFax Protect) complete with signed BAAs and legal audit logs. MyFax caters primarily to standard commercial businesses and lacks the specialized regulatory security protections necessary for compliant PHI transmission.
