AUSTIN, Texas – Oct. 19, 2006 – NetQoS^® Inc. announced that it ranked Number 72 on Deloitte’s 2006 Technology Fast 500, a ranking of the 500 fastest growing technology, media, telecommunications and life sciences companies in North America. Rankings are based on percentage revenue growth over five years, from 2001–2005. NetQoS grew 3,347 percent during this period, exceeding the 2,145 percent average growth rate for companies on the 2006 list.

“As the delivery of applications to remote workers and offices across the country and around the world becomes more critical and complex, large organizations are turning to NetQoS to simplify network performance management,” said Joel Trammell, NetQoS CEO. “Our growth stems from our ability to give customers centralized visibility into network performance and the cause of bottlenecks across all locations, to improve application delivery and plan for change.”

“Sustaining high revenue growth over five years is an exceptional accomplishment. We are proud to honor NetQoS’ ranking on the Deloitte Technology Fast 500 list for the third consecutive year,” said Tony Kern, deputy managing principal of Deloitte’s Technology, Media & Telecommunications industry practice. “We commend NetQoS for making the commitment to technology and delivering on the promise of market longevity.”

In addition to ranking on Deloitte’s Technology Fast 500, NetQoS ranked seventh on the Texas Technology Fast 50, which is a list of the 50 fastest growing technology firms in Texas. NetQoS was also named today to the Software 500, a ranking of the world’s largest software companies, and recently made the 2006 Inc. 500, a list of the nation’s fastest growing privately held companies.
