Zix Corporation Releases ZixVPM Version 2.3; Latest Version Includes New Platform and New Convenient Functions to Meet Customer Demand.

DALLAS -- Zix Corporation (ZixCorp(R)), (Nasdaq:ZIXI), a global provider of secure e-messaging, e-prescribing, and e-transaction applications and services, today announced the availability of the latest version of its enterprise-wide email encryption solution, ZixVPM(R) (Virtual Private Messenger).

ZixVPM 2.3 is offered on a new platform, Dell 1850 or Dell 750, with superior hardware support. It also includes features requested by current users, including new routing options for greater flexibility, increased interoperability, and the ability to control when email is encrypted.

New features of ZixVPM 2.3 include:

--New routing capabilities that enable options such as forwarding messages to administrator, customized bounce messages, action notifications to sender, and blocking incoming mail per policy

--End-user ability to force messages to be sent in plain text or to encrypt on demand

--An S/MIME interoperability module

--Support for Transport Layer Security (TLS)

--Enhanced and more robust lexicons with concise terminology

--Improved performance and security updates, including content scanning and no unnecessary scanning of binary files 

Several customers, including Detroit Medical Center, conducted beta testing of ZixVPM 2.3. "With ZixVPM 2.3 we have measured a 50 percent improvement in our mail flow response times," said Eric M. Foote, manager, Intel Server Group for Detroit Medical Center Information Services. Stability has also improved, including less hands-on administrative time required. The granularity of the message classification has also greatly improved thereby giving us greater control of our encryption policies."

ZixVPM is a server-based enterprise solution for organizations that require a high level of email security and encryption. The service provides a secure e-messaging gateway without the need to create, deploy, or manage end-user encryption keys and software. It offers send-to-anyone capability, corporate-defined policy management, and remains transparent to end users.

"ZixVPM has proven to be an ideal solution for a variety of business sectors that handle sensitive information, including securing HIPAA information for the healthcare community and sensitive account numbers and other private data for the financial community," said Nigel Johnson, vice president of business development and product management for ZixCorp. "We currently have more than 200 ZixVPM customers and 300,000 contracted seats, and encrypted messages have been sent to more than four million unique addresses through our ZixData Center(TM) using our Best Method of Delivery(TM). The enhancements to this latest version help expand functionality and provide a flexible, easy-to-use solution, while continuing to provide accelerated installation for a system-wide encryption solution."

ZixVPM 2.3 is currently available to new customers and there will be a phased release to existing customers.
