Our Differentiators

For the easiest email encryption, look no further than Zix.

When you use Zix Email Encryption, you experience a secure email as easy as conventional email. How can we do it when nobody else can?

From the beginning, we believed that if email encryption was going to be used by everyday business professionals (aka people outside IT), it had to be easy. And that’s why more than 15 years ago, we based our technology on a unique, community approach where members could communicate securely without any effort.

Supported by ZixDirectory and Best Method of Delivery, we take care of encryption and decryption, and in the process, we better protect your sensitive data in email, strengthen communication with your most valuable customers and partners, and assist you with any compliance needs.

Transparent Email Encryption

No passwords, no extra steps

Our greatest differentiator is the industry's only fully transparent delivery of encrypted email. With transparent email encryption, your users send and receive secure email as they would conventional email. No extra steps or passwords are required, and workflow is not interrupted. We manage the complexity, so it's transparent to both your senders and recipients.

How transparent will your encrypted email be? On a typical business day, Zix encrypts around 1,000,000 messages for our customers. On average, 75 percent of these encrypted messages are sent transparently without any extra steps or passwords.
