Zix Corporation provides e-communication services that protect and deliver sensitive information to enterprises and consumers in the healthcare, finance, insurance, and government sectors primarily in the United States. It operates through two segments, Email Encryption and e-Prescribing. The Email Encryption segment designs and develops Email Encryption Service, a hosted service that analyzes and encrypts email communications, and addresses reporting needs.

This segment also provides related advisory, installation, customization, and training services. The e-Prescribing segment designs and develops its e-Prescribing solution, which enables medical providers to write and transmit prescriptions electronically from the point of care directly to the pharmacy. In addition, this solution offers point-of-care access to drug formularies and drug data. This segment distributes its products and services directly to physicians and healthcare institutions.
