Many digital fax solutions use e-mail and e-mail servers to transport their fax messages at some stage. But in SEFOS' solution for digital fax, we have completely eliminated all use of e-mail to transport the personal data that may be contained in a digital fax message. This creates a safer solution with fewer involved services and technical steps in the chain, which minimizes the risk of incidents. In the GDPR, this is simply called "privacy by design".
