Belmont, Calif. - May 11, 2005 - NetQoS Inc., the fastest-growing provider of performance analysis products and services for Global 2000 networks, today announced that it has been named one of the Red Herring 100 Private Companies of North America.

"Five years after the dot-com bubble burst, innovation and entrepreneurship are thriving. The companies on this list are proof," said Red Herring editor-in-chief Joel Dreyfuss.

"As delivery of applications over wide area networks becomes more complex, enterprises are turning to NetQoS to help them improve networked application performance with products that scale globally and provide the depth of information needed to solve hard problems," said Joel Trammell, NetQoS CEO. "With a growing list of more than 250 large enterprise customers and a 17,400 percent revenue growth rate since 1999, we are honored that Red Herring has recognized us as one of the top 100 Private Companies of North America."

Red Herring's lists of private companies are an important part of the magazine's tradition of identifying new and innovative technology companies and entrepreneurs. Companies like Google and eBay were spotted in their early days by Red Herring editors as those that would change the way we live and work.

Red Herring's editorial staff rigorously evaluated more than 900 private companies through a careful analysis of financial data and subjective criteria, including quality of management, execution of strategy, and dedication to research and development.  Red Herring 100 companies, including NetQoS, will be presenting their business model and strategy at the Red Herring Spring conference, which will take place May 17-19 at the Monterey Plaza Hotel in Monterey, Calif.
