The company was founded in January 2001 by Martin Roesch, author of open source Snort®, the world’s most downloaded intrusion detection and prevention technology with nearly 4 million downloads to date. In response to increased demand for a commercial version of the popular software, the company developed the Sourcefire 3D^® System—a systematic network defense system built on Snort and designed to adapt to dynamic networks and threats in real-time. Sourcefire's strong commitment to innovation continues to break new ground.

The company’s solutions and open source technologies are deployed in nearly all of the Fortune 100 companies, in over 50% of the Fortune 500 companies and across all branches of the military as well as in the largest civilian government agencies.

Sourcefire currently manages some of the world’s most respected open source security projects including Snort and ClamAV^®, the most commonly used open source anti-virus and anti-malware product in the world. Through this connection to the open source security community, Sourcefire offers organizations of both worlds—open source collaboration and innovation teamed with a fully commercially supported solution.
