Security for the Real World
Sourcefire was founded in 2001 by Martin Roesch, the original author of Snort,
in response to increasing demand for a commercial version of the popular technology.
Today Sourcefire’s mission is to combine our open source roots with
proprietary innovation to deliver the most effective and comprehensive real-time
network defense solutions on the planet.
Over the past several years, Sourcefire has contributed increasing resources
to advancing the Snort technology. That commitment has resulted in advances
such as gigabit performance capability, the integration of the snort_inline
technology, the current and future generations of IP defragmentation and
TCP stream reassembly functionality, protocol anomaly detectors and normalization,
portscan detection, the unified output subsystem, reams of documentation
and two complete code audits. In addition, we have developed the Sourcefire
Vulnerability Research Team and dedicated significant resources to improving
the quality, accuracy and timeliness of Snort rules.
Today, Sourcefire combines the very best of open source with the best of
the commercial world. Leveraging the power and reach of the open source
Snort rules-based detection engine, Sourcefire adds a critical layer of
asset and behavioral profiling. Sourcefire’s RNA (Real-time
Network Awareness) maintains a persistent profile of a network and its assets.
Using passive discovery methods, RNA adds a new level of visibility and
intelligence.
Sourcefire’s 3D Approach – Discover, Determine, Defend – provides
a fully integrated, real-time process of discovering risks, vulnerabilities
and threats; determining their business impact; and taking the most precise,
appropriate action to defend the network. The Sourcefire 3D System,
comprised of Sourcefire Intrusion Sensors and Agents, Sourcefire RNA and
the Sourcefire Defense Center, is a comprehensive intelligent network defense
system that unifies intrusion and vulnerability management technologies
to provide customers with the most effective, real-time network security
for today’s real world challenges.
Sourcefire remains committed to the open source development model and will
continue to support the open source community and dedicate increasing resources
to advancing the development of Snort and the Snort rules language. In addition,
we dedicate the necessary resources to hosting the snort.org web site to provide
the community with the most up-to-date information about the technology and
industry. The result is a win-win for bringing truly effective network security
for the real world.
