PRESS RELEASE

DALLAS --(Business Wire)-- Mar 02, 2010 Zix Corporation (ZixCorp'), (Nasdaq: ZIXI), the only email encryption service designed with your most important relationships in mind, today announced the next generation of the Company's Email Encryption Service. Highlights of this announcement include new versions ZixGateway' 4.0 (formerly ZixVPM') and ZixPort' 3.7.

ZixGateway 4.0 is the latest generation of the Company's directory driven (ZixDirectoryTM), policy-based Email Encryption Service. ZixGateway 4.0 continues to allow ZixCorp customers to send and receive secure email automatically and transparently while delivering new capabilities including support for virtualization, multiple languages and DKIM.

"In addition to these new capabilities, the next generation of the ZixCorp Email Encryption Service successfully maintains the quality that customers have come to expect from ZixCorp while continuing to allow automatic, transparent delivery of encrypted messages," said Rick Spurr, Chief Executive Officer of ZixCorp. "ZixCorp's Email Encryption Service has always been easy to use, which is ideal for healthcare companies, financial companies or government systems of any size. Our SaaS architecture eliminates the intense time and resources spent managing in-house email encryption. Our clients are able to upgrade to the new ZixGateway 4.0 and ZixPort 3.7 transparently."

Organizations across a wide spectrum of industries including financial services, healthcare and government are looking for ways to transform their IT organizations. With support for virtualization, ZixGateway customers can reduce capital and operating costs with a scalable infrastructure for email encryption.

ZixCorp's continued growth and success with partners and large enterprises has driven further expansion of ZixCorp's language support in the ZixDirect component of ZixGateway. With ZixGateway 4.0, customers and partners can now support a wide array of languages when utilizing our email encryption capabilities.

Many financial and government organizations are continuing to work towards protecting their customers from phishing and spam, and with ZixGateway 4.0, ZixCorp is supporting these efforts with the addition of DKIM support. DKIM provides email sender authentication that provides email recipients with added protection.

ZixGateway is a policy-based email encryption appliance for enterprise-wide regulatory compliance. It provides company-wide security, content filtering, and management of outbound corporate email.
