Market Wire, February, 2008

Zenoss, Inc., a leading provider of open source network and systems management software, today announced that Zenoss Core has been named a finalist in the Software & Information Industry Association's (SIIA) 23rd Annual CODiE Awards. Since 1986, The CODiE Awards have recognized outstanding achievement and vision in the software, digital information and education technology industries. Zenoss Core is an integrated open source IT management software solution that allows IT administrators to track the configuration, performance and health of their IT environment.

"We are proud to be recognized as an industry leader and the standout solution in open source IT management," said Bill Karpovich, Zenoss CEO and Co-Founder. "Thousands of organizations -- including several in the Fortune 500 -- have come to us to better manage their network, server and application infrastructure. Every day, organizations are realizing that they don't have to accept the same old solutions that have been frustrating users for years."

As the very first commercial open source IT management solution to include a configuration management database (CMDB), the Zenoss solution is a complete network monitoring and systems management platform that discovers networked IT resources, monitors them for performance and availability, and tracks changes through the CMDB. The end result is a very cost-effective way to ensure the systems uptime for servers, applications and networks throughout the enterprise.

Zenoss Core is one of the ten most active projects on SourceForge.Net, and has been downloaded over half a million times. It also consistently ranks in the top five downloaded solutions among over 1,600 network monitoring projects.
