How eFax Secure Works

When you receive a fax through your secure fax account, the service automatically and immediately encrypts the fax — using 256-bit encryption — and stores it securely in your account online while notifying you (via email) that the fax is available.

Included in this email notification is a URL. When you click on the link, a Transport Security Layer (TLS) connection is made and you will be prompted for your eFax Secure credentials (login ID and PIN) to view the fax. eFax Corporate has upgraded from the vulnerable SSL encryption to the new and even more secure encryption protocol TLS.

No sensitive information is ever directly transmitted, as the fax remains on our server – you view it from there. Additionally, the fax can remain encrypted and securely stored as long as you need it, reducing strain on your local email servers and storage devices1.
