SOURCEFIRE LAUNCHES ENTERPRISE THREAT MANAGEMENT STRATEGY

Delivers Integrated Intrusion Prevention, Network Behavior Analysis, Network Access Control and Vulnerability Assessment

Open source innovator and Snort creator, Sourcefire, Inc. (Nasdaq: FIRE), a leader in network intrusion prevention, today announced its Enterprise Threat Management (ETM) strategy, along with the introduction of the Sourcefire Master Defense Center and post-connect network access control (NAC) functionality.

"The key to effective and efficient network security is intelligence - threat, network, endpoint and user data that can be correlated and leveraged to drive more precise and accurate protection," said Scott Crawford, Senior Analyst at Enterprise Management Associates. "Enterprises can no longer afford to implement 'point' solutions that are managed separately and don't share intelligence. Sourcefire's ETM strategy offers a fresh approach to defending dynamically changing networks by integrating four key network security technologies under one management console."

Built on a common foundation of threat, network, endpoint and user
intelligence, the Sourcefire 3D System (TM) unifies four key ETM solutions -
Intrusion Prevention (IPS), Network Behavior Analysis (NBA), Network Access
Control (NAC) and Vulnerability Assessment - to defend enterprise networks
at all stages of the attack continuum - Before, During and After the attack.
Sourcefire is the first network security vendor to integrate all four ETM
components under the same management console, affording customers with both
efficient and effective means for defending complex networks against today's
most costly threats.

With this new ETM approach, Sourcefire customers can:

• Defend against known and unknown exploits using Sourcefire's award-winning
  IPS solution, built on Snort open-source technology;
• Capture traffic baselines and detect internal network anomalies using
  Sourcefire's NBA solution;
• Enforce network and regulatory compliance policies using Sourcefire's
  post-connect NAC solution;
• Determine vulnerabilities in network assets to mitigate threats using
  Sourcefire's Vulnerability Assessment solution.

Coinciding with Sourcefire's ETM announcement, Sourcefire is also
introducing the Sourcefire Master Defense Center (MDC), enabling global
enterprises to achieve new depths of enterprise-class scalability.
Aggregating security and policy events from up to ten subordinate Defense
Center appliances, the MDC enables enterprises with multiple Defense Centers
to view and prioritize events from one web-based management interface.

Sourcefire is also introducing Network Usage Control, a powerful
post-connect NAC capability, that enables customers to set and enforce
policies dictating acceptable network user behavior. Through the Sourcefire
Defense Center, customers can create a "whitelist" of compliance profiles
and baseline configurations of acceptable behavior and then leverage RNA's
24x7 passive monitoring to identify policy and regulatory non-compliance.
Notifying users immediately of any policy violations, Network Usage Control
is designed to enable organizations to minimize network security risks,
create and achieve internal and/or regulatory compliance, and ultimately
lower IT support costs.

"It is time for the industry to start working smarter, not just harder, to
address the network security problem," said Marty Roesch, Sourcefire Founder
and CTO and creator of Snort. "Traditionally, for every new type of threat,
organizations have been forced to deploy a new type of box. Because these
'point solutions' are usually managed separately, they generally cannot
share intelligence and they often yield low returns on investment. Through
Sourcefire's new ETM approach, we are delivering integrated solutions that
are designed to efficiently and effectively solve real-world security
problems, without requiring customers to make new investments for every new
risk."
