eFax Secure™ protects your business's faxes

With eFax Secure™, your faxes are sent with the highest grade TLS encryption, recently upgraded from SSL, in transit and are stored in your secure, web-based inbox, using 256-bit encryption. When a fax comes in, eFax Secure™ sends an email, with a URL, to the recipient. The user simply clicks the URL (opening an TLS connection) and enters his or her eFax Corporate account information to view the secure fax. It’s safe, easy to use, and can be deployed in minutes.
