The newly patented system has features that are designed to simplify the process of sending and receiving encrypted email, the company said.
The features include real-time public key retrieval, "transaction certificates," and sending encrypted messages using a non-SMTP protocol through a forwarding server.
The patent is the third awarded to Zix this year. Previously, the Dallas-based company received patents for a secure message forwarding system and transaction authorization system.
