Zenoss Closes Record Quarter With Over 100 Enterprise Customers, Opens New Development Center in Austin, Texas

Open Source Vendor Establishes Presence in Systems Management Hotbed

AUSTIN, TX and ANNAPOLIS, MD--(Marketwire - April 21, 2008) - Zenoss, Inc., a leading provider of open source network and systems management software, propelled by explosive customer growth has expanded their operations to Austin, Texas through the addition of a new software development center. The Austin development team collectively comprises over fifty years of experience bringing enterprise-class systems management software to market. The Zenoss Austin office will be located in the same building where management software innovator Tivoli was started and since acquired by IBM. Austin was chosen for its wealth of talent and access to expertise in a market segment estimated by Gartner Research to grow to $18.1 billion dollars by 2012.

"Over the years Austin has built up an IT management talent pool that's showing its muscle once again as evidenced by Zenoss' new Austin office and Solarwinds' filing for an IPO," noted Austin-based IT analyst Michael Coté of RedMonk. "The developers, architects, management, and marketers here have spent years building up the skills required to grow and maintain IT management companies. Because IT management solutions address unique and challenging problems for the companies that use them, it can be difficult to find personnel with the specialized skills to develop, scale and support them. Luckily, Austin has managed to hold onto the talented people that can deliver on those needs to the benefit of numerous IT management companies, big and small, new and old."

Zenoss' need for expansion is fueled by the rapid growth of its commercial customer base which grew to over 100 in the quarter, including over 25 public companies and three in the Fortune 100. Recent customers include Disney, Georgia Tech, CleverSafe, Montavista and Instinet, among others. Beyond commercial success, the company has grown its open source community to over 30,000 members and 3,500 active deployments. In March, the company released Zenoss for Service Providers, a solution designed to meet the unique needs of xSPs. Initial service providers using Zenoss include OmniPresence, OpSource and SugarCRM.

"Following a banner year in 2007, we opened 2008 by adding 32 new enterprise customers, our most successful quarter ever," stated Zenoss CEO Bill Karpovich. "Not only have we increased the number of customers, but bookings have increased by 90% over the prior quarter. We believe that the market's appetite for affordable yet powerful management products like Zenoss Enterprise will only continue to grow."
