The analog machine is familiar. It is also a shared device with no identity, a paper trail that walks away, and busy signals that turn into "just email it to my Yahoo."
Compare the controls
- Identity: cloud fax uses staff accounts; the machine uses whoever is standing there.
- Exposure: printed pages vs encrypted storage and a HIPAA inbox.
- Evidence: a transmission log you can search vs a fading confirmation strip.
- Wrong number: both can misdial; only one keeps a record you can investigate.
Migration without drama
Keep the published fax number. Point it at cloud fax. Teach staff fax-to-email for inbound packets and a cover-sheet habit for outbound. Retire the machine when the tray stays empty for two weeks.
HIPAA Companion secure fax is built for that cutover. It sits with email and forms so a referral that arrives as a fax can be answered as a message or a form packet without leaving the same BAA.
