Zix Corporation's ZixDirectory Surpasses 9 Million Members

World's Largest Email Encryption Directory Continues Rapid Growth of More Than 60,000 New Members Per Week Across Healthcare, Financial Services and Government Sectors
DALLAS, Oct 1, 2007 (PrimeNewswire via COMTEX News Network) -- Zix Corporation (ZixCorp(r)) (Nasdaq:ZIXI), the leader in hosted services for email encryption and e-prescribing, today announced that ZixDirectory(tm), the core of the Company's encryption service offering, marked a new milestone, surpassing more than nine million members.

ZixDirectory is the industry's largest global directory of email recipients, containing influential healthcare, financial services and government organizations. ZixCorp is the only email encryption provider to offer its clients immediate access to over nine million members. The directory provides a centralized mechanism for automatic key exchange, greatly enhancing ease-of-use for both senders and receivers.

ZixDirectory secures communities of interest in healthcare, finance and government. In the August 27 issue of Government Computer News, the article "Email you can bank on" by William Jackson highlighted ZixCorp's communities of interest, stating that the two largest communities the Company now serves are the financial services and healthcare industries. Federal, state and county governments are also a fast-growing market for ZixCorp, including regulatory agencies such as those served by the Conference of State Bank Supervisors (CSBS) and agencies that deliver citizen services.

Included in the article was a quote by ZixCorp customer Mary Beth Quist, CSBS senior vice president. "This solution seemed to work best for the states because they had options," Quist said. "Agencies using ZixCorp's E-mail Encryption Service can send secure e-mail messages to other agencies even if they are not ZixCorp customers. The first state regulators began signing up in 2005."

Rick Spurr, chief executive officer for ZixCorp, added, "As the ZixDirectory continues to expand, currently growing at a rate of 60,000 new members per week, the attractiveness of our service increases for prospective customers and for existing customers as well. Both the size of the directory and quality of its members give us an asset that's not easily replicated. We have found that a large number of the people our customers communicate with via email are already members of our directory. Without a large central directory, a company implementing email encryption must establish secure relationships with all of their customers and partners, adding significant effort and complexity for encryption users. The power of the ZixDirectory, the hosted nature of our service, the ease of use of the technology, and our send-to-anyone capabilities are reasons why we are a leader in the industry."

ZixCorp is the leader for email encryption services in the healthcare sector, with three of the top insurance companies, 30 Blues organizations, and over 900 hospitals as customers. ZixCorp's success with financial regulators, including the federal banking regulatory agencies and 15 state banking regulators, has led to growth in its financial services customer base, including over 500 financial institutions and leading insurance companies. ZixCorp supports five encrypted email delivery mechanisms, including S/MIME, TLS, OpenPGP, secure portal and "push" delivery.
