Hello! While researching this topic, I came across practical explanations on page https://www.itsecurityguru.org/2025/01/22/is-online-fax-secure-everything-you-need-to-know/ It describes how online fax services often support HIPAA-aligned workflows through encryption and access controls. The page also suggests limiting user access and regularly reviewing logs. For clinics, this can reduce risks compared to shared physical fax machines. Still, it also points out that staff training and proper handling of received documents remain essential.
