SOURCEFIRE EXPANDS IPS SUPPORT

New 3D6500 Sensor Provides Users with Cost-Effective, Scalable Appliance for Intrusion Prevention, Network Visibility and User Awareness Wokingham, UK, 14th April 2009 – Open source innovator and Snort® creator, Sourcefire, Inc. (Nasdaq:FIRE), a leader in Enterprise Threat Management, today announced its new 3D6500 Sensor, offering up to 4Gbps of IPS inspection while providing the ability to interface with 10G fiber networks. Adding to Sourcefire’s 10G intrusion prevention system (IPS) leadership, the 3D6500 augments the scalability and flexibility of the Sourcefire 3D® System’s complete line of network security appliances, enabling customers to select the sensor that best suits their requirements. “Today, customers are not simply looking for network security solutions that solve their current needs, but ones that can easily scale to address future requirements, which is why Sourcefire is continuing to invest in delivering the most flexible products on the market,” said Tom Ashoff, vice president of engineering at Sourcefire. “With the addition of the 3D6500 Sensor, we are building out our support for 10G networks, so that customers can implement the exact solution to meet their ongoing needs.” Available now, the 3D6500 Sensor offers up to 4Gbps of IPS inspection in a 2U form factor appliance. As is the case with all Sourcefire 3D Sensors, the 3D6500 features integrated copper and fiber bypass (fail-open) technology—a critical requirement for inline IPS deployments—foregoing the need to acquire costly external bypass devices. The 3D6500 Sensor is optimized to support simultaneous execution of IPS, RNA® (Real-time Network Awareness) and RUA™ (Real-time User Awareness) processes, and is available in the following configurations: • 12 1Gbps copper ports • 4 10Gbps SR/LR fiber ports • 6 1Gbps copper ports and 4 1Gbps fiber ports • 6 1Gbps copper ports and 2 10Gbps SR/LR fiber ports The Sourcefire 3D System enables organizations to protect their dynamically changing networks with increased confidence, providing customers with a unified platform for protecting both physical and virtual systems. As the industry’s only “Adaptive IPS,” the 3D System enables customers to optimize the security and performance of their IPS systems based on the actual network assets they are protecting. The ongoing process of IPS tuning can be highly automated, thus increasing security effectiveness while reducing management overhead. Powered by open source Snort as its detection engine, the Sourcefire 3D System is consistently recognized as one of the industry‘s leading and most innovative intrusion prevention systems. Backed by the Sourcefire Vulnerability Research Team™ (VRT), a group of leading edge intrusion detection and prevention experts and a community of over 225,000 registered Snort users, the Sourcefire 3D System helps to protect customers from both known exploits and zero-day threats.
