Built on the legacy of Sourcefire’s Snort® rules-based detection engine, Sourcefire IPS™ (Intrusion Prevention System) uses a powerful combination of vulnerability- and anomaly-based inspection methods—at throughputs and line speeds up to 10 Gbps—to analyze network traffic and prevent critical threats from affecting your network. Whether deployed at the perimeter, in the DMZ, in the core, or at critical network segments, and whether placed in inline or passive mode, Sourcefire’s easy-to-use IPS appliances provide comprehensive threat protection. 
Most providers offer a “one-size-fits-all” IPS, but Sourcefire is different. Our solution is divided into three customer protection phases—IPS, Adaptive IPS, and Enterprise Threat Management (ETM)—with each phase building upon the benefits and features of the previous one, adding capabilities to optimize a company’s network protection.
IPS
Based on the award-winning Snort detection engine, Sourcefire IPS provides best-in-class intrusion defense with extensive analytics, powerful reporting, and unrivaled scalability. Through the use of Sourcefire 3D® Sensors and one or more Sourcefire Defense Center™ management consoles, the IPS phase enables you to detect and/or block attacks targeting thousands of vulnerabilities.
Adaptive IPS
Sourcefire is the first to offer an Adaptive IPS strategy. The Adaptive IPS phase incorporates the real-time/all-the-time network intelligence from Sourcefire RNA™ (Real-time Network Awareness) to enable automated threat impact assessment and automated IPS tuning, saving you considerable time and effort. Adding RNA to your 3D Sensors significantly reduces false positives and false negatives and allows small-sized IT security staffs to effectively monitor large networks.
Enterprise Threat Management (ETM)
Sourcefire’s ETM phase provides all-the-time/real-time knowledge of attacks, targets, and the state of your critical systems fully integrated into one system. It couples Sourcefire’s IPS solution with additional ETM capabilities, including user identity tracking, network behavior analysis (NBA), and IT policy compliance. With Sourcefire’s ETM, you have the tools necessary to defend your network before, during, and after the attack.
No matter whether your organization is small or large, new to IPS or more experienced, Sourcefire offers an IPS solution to meet your network security needs—today and tomorrow.
