Protect Your Business with Secure Faxing

Proven, Trusted Method of Secure Online Faxing

Our 20-year record of protecting the most sensitive communications is why businesses in the most highly regulated industries — including large healthcare providers, financial and legal firms — depend on our secure fax services for their document transmissions.

TLS Encrypted Faxing

eFax Secure can send your faxes by email with highly advanced TLS encryption, recently upgraded from SSL. This ensures your fax documents are protected in transit from their point of origin on your company’s network to your recipient’s fax. When a fax is sent to one of your employees, eFax Secure will send that employee an email with a URL to a secure website. The employee then simply clicks the URL (opening a TLS connection) and enters their eFax Corporate account information to view the secure fax. It’s safe, easy to use as email, and can be deployed in minutes.
