PRESS RELEASE

SAN FRANCISCO --(Business Wire)-- Mar 02, 2010 MANDIANT, the leading provider of incident response and computer forensics solutions and services, and Bit9, the pioneer and leader in Enterprise Application Whitelisting, today announced a strategic technology and distribution partnership at RSA Conference 2010 in San Francisco. MANDIANT will offer integrated access to the Bit9 Global Software RegistryTM (GSR) from the MANDIANT Intelligent Response' (MIR) incident response software to accelerate incident response investigation. The combination of MANDIANT's incident response offerings and Bit9's application whitelisting solution provides an essential defense-in-depth approach to Advanced Persistent Threat (APT) intrusions.

Bit9 GSR, a cloud-based software reputation service powered by a database containing 7.5 billion records of metadata covering millions software titles, enables "background checks" on new and unknown software. MANDIANT will use the Bit9 GSR in its MIR product and professional services engagements to identify and eliminate trustworthy software from forensics investigations to help accelerate the process.

Bit9 GSR, combined with MANDIANT's MIR, the industry's first enterprise-grade incident response solution, solves the challenge of identifying both known and unknown software executable files. For enterprise security teams, the technology collaboration accelerates response time and reduces the costs associated with incident response mitigation and investigation.

Michael Montecillo, Principal Analyst with Enterprise Management Associates' Security & Risk Management practice, said customers will be able to leverage industry-leading technology in both endpoint protection and incident response.

"The combination of the two serves to reduce the number of incidents an organization experiences and at the same time minimizes the impact of any successful attacks," Montecillo said. "For an enterprise, this means cost savings through better effectiveness of already existent processes."

MANDIANT Vice President of Products, Dave Merkel, agreed, adding that incident response teams are focused squarely on minimizing the financial and operational impact of incidents, and that leveraging a cloud-based software reputation service as a form of whitelisting is a natural step forward in the continuing sophistication and evolution of risk management and incident response.

"We are pleased to join forces with Bit9," Merkel said. "The GSR-MIR integration will measurably speed response time, reduce down time and ultimately curtail the financial and operational risk exposure our clients face whenever attacked."

Doug Cahill, Vice President of Business Development from Bit9, noted that Bit9's GSR software reputation service combined with Bit9 Parity's automated software approvals are essential elements in an application whitelisting solution as well as in incident response.

"Bit9 is proud to join forces with MANDIANT," Cahill said. "Combining Bit9 GSR with MANDIANT's MIR will reduce incident response times, ultimately benefiting our joint customers, including government agencies."
