Qualys, Inc. Receives Top Ranking in Deloitte's Technology Fast 50 For Third Consecutive Year

REDWOOD CITY, Calif. - October 31, 2008 - Qualys®, Inc., the leading provider of on demand IT security risk and compliance management solutions, today announced for the third consecutive year it has been named to The Silicon Valley Technology Fast 50 Program, which honors the fastest growing software and information technology companies in the San Francisco Bay Area. Based on revenue growth over the five-year period from 2003 to 2007, Qualys demonstrated a five-year growth rate of 492 percent.

“We are honored to have received the Deloitte Fast 50 and we share this recognition with our customers who have supported our efforts to bring the SaaS model to security,” said Philippe Courtot, Qualys CEO. “This effort has helped corporations of all sizes to have a clear view of their security and compliance posture of their networking infrastructure and applications and a streamlined process for remediation - all with no software to install and maintain.”

“To make the Technology Fast 50, companies must show remarkable revenue growth over the past five years,” said Mark Jensen, Managing Partner, National Venture Capital Services, Deloitte & Touche LLP, in Silicon Valley. “Qualys is one of the Silicon Valley success stories with its impressive growth record and we congratulate them on this industry recognition.”

To qualify for the Technology Fast 50, companies must have had operating revenues of at least $50,000 in fiscal year 2003 and $5,000,000 in fiscal year 2007, be headquartered in the San Francisco Bay Area, and be a company that owns proprietary technology or proprietary intellectual property that contributes to a significant portion of the company’s operating revenues; or devotes a significant proportion of revenues to the research and development of technology. Using other companies’ technology or intellectual property in a unique way does not qualify.

Companies from the regional Technology Fast 50 programs in the United States and Canada are automatically entered in Deloitte’s Technology Fast 500 program, which ranks North America’s top 500 fastest growing technology, media, telecommunications and life sciences companies.
