Zix Corporation (ZixCorp(TM)), (Nasdaq:ZIXI), a global provider of protection, management, and delivery solutions for electronic communications, today announced a contract with the Office of the Comptroller of the Currency (OCC), a bureau of the U.S. Department of the Treasury, for secure e-messaging to ensure a safe method of communication for confidential information with all major financial institutions in the country. The OCC charters, regulates, and supervises all national banks to ensure a safe and competitive banking system that supports the citizens, communities, and economy of the United States. OCC selected ZixVPM(R) (Zix Virtual Private Messenger) for 250 users, a gateway solution providing policy-driven secure email, to ensure complete interoperability with other financial institutions whether or not they currently use ZixCorp services. By protecting confidential information being sent via email, companies are working to comply with the Gramm-Leach-Bliley Act (GLBA), which includes provisions to protect consumers'personal financial information held by financial institutions. OCC also purchased ZixPort(TM), an integrated secure e-messaging portal that mirrors the look and feel of the organization's existing Web portal.

'We are proud to have one of the most highly respected organizations in the world choose us to secure its email communication,'says John A. Ryan, chairman, president, and CEO of ZixCorp. 'Organizations like the OCC that have to deal with thousands of different institutions around the world can look to our solutions to provide instant interoperability and send-to-anyone technology. We are glad to see a growing trend towards securing confidential information being sent over the Internet within government agencies and financial institutions. With the acceleration of hacker activity and the high risk of misrouting messages, the importance of securing this data can't be overstressed. Financial institutions come to ZixCorp because we have proven ourselves over and over to be a trusted partner in email protection services.'

The OCC joins a number of prominent financial institutions that are already using ZixCorp services, including: American Savings Bank, Baker Boyer Bank, Bank von Ernst, Cape Cod Bank and Trust, Farm Credit Financial Partners, Hawthorne Savings Federal Savings Bank, Marshall & Ilsley Corp., Provident Bank, Red Capital Group, Savings Bank of Manchester, United Security Bank, and Wilber National Bank.
