BOULDER, CO - October 17, 2005

Webroot Software, Inc., the leading provider of anti-spyware software and other security technologies for consumer and enterprise markets, today announced that it has been named to Deloitte's prestigious Technology Fast 50 Program for Colorado, a ranking of the 50 fastest growing technology companies in the state by Deloitte & Touche USA LLP, one of the nation's leading professional services organizations.

"Deloitte's Colorado Technology Fast 50 companies have shown the strength, vision and temerity to succeed in today's very competitive technology environment," said Steve Yaroch, Technology, Media and Telecommunications Lead Partner for Deloitte & Touche LLP in Denver. "We applaud the successes of Webroot and acknowledge it as one of the very few to accomplish such a fast growth rate over the past five years."

Deloitte's Technology Fast 50 companies must be headquartered in North America and be defined as a company that owns proprietary technology 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. The companies are ranked based on percentage of revenue growth over five calendar years. Webroot's increase in revenues of 374 percent from 2000 to 2004 resulted in an 11th ranking in the Technology Fast 50 for Colorado. The rankings were revealed at the 2005 Fast 50 CEO event on Thursday, October 6 in Denver.

"We are extremely proud of this accomplishment and to be recognized by such a prestigious program as the Deloitte Technology Fast 50," said C. David Moll, Webroot's CEO. "The complexity and pervasiveness of the spyware problem has increased exponentially during the past three years. Keeping ahead of the problem and proactively protecting consumers and enterprises is a challenge that we welcome every day. This challenge will continue to drive us our momentum as we maintain our impressive growth pattern for many years ahead."
