Bit9 Continues to Lead Application Control Marketplace with its Desktop Lockdown Offerings, Achieving Significant Momentum in 2006.

CAMBRIDGE, Mass. -- Bit9, Inc., the leading provider of desktop lockdown and application control solutions, kicked off the new year with significant momentum from a banner year in 2006 and a strong start to the first quarter.

Bit9 today announced that its ParityCenter knowledgbase, the world's largest database of applications used for file identification, now tops 2 billion file records, an 800% increase in the size of the database since its inception in March of 2006. Hundreds of thousands of people around the world have accessed the database through Bit9's FileAdvisor service, a free subset of the information. Bit9 recently beefed up the database by adding links to new sources of information such as Microsoft Security Bulletins, and entries from Common Malware Enumeration, Common Vulnerability Enumeration, CERT Vulnerabilities, SANS Vulnerabilities, among others.

In addition to these worldwide users, Bit9 signed up numerous enterprise marquee customers, racking up 500% growth in its customer base. These customers use Bit9's solutions to achieve desktop lockdown, resulting in better desktop security, higher availability, and ultimately, full compliance with IT policies across the enterprise. As well, Bit9 increased its sales distribution channels by partnering with nearly a dozen key resellers in security and desktop management software.

"2006 saw the emergence of application control solutions as a viable alternative for keeping malware and spyware off of desktops. These applications are providing a comprehensive, bona fide solution where traditional signature-based anti-virus software is falling short," said Robin Bloor, founder of Bloor Research and a partner with Hurwitz & Associates. "Bit9 has gained traction in this market due to its comprehensive data on commercial software, its graylisting capabilities, and the strong foundation of its installed base."

Bit9 also announced today that it had appointed its first Vice President of Business Development to its executive team, Doug Cahill. Bit9 was recently named a finalist in the SIIA's CODiE awards and also received the Bronze Product of the Year Award from TechTarget, following on a strong year of other awards.

"Bit9 is thrilled to have accomplished such a banner year for the company in 2006," said Tom Murphy, Chief Marketing Officer of Bit9. "The success Bit9 has achieved this year is a testament to the market demand for Application Control software and proves that Windows desktop administrators are looking for innovative tools to enforce their desktop usage policies. This significant momentum will position us as the leader in Application Control to further Bit9's success in the coming years."
