Snort is a free open source network intrusion detection system (IDS)[5] created in 1998 by Martin Roesch, former founder and CTO of Sourcefire.[6][7] Snort is now developed by Cisco, which purchased Sourcefire in 2013, at which Roesch is a chief security architect.[8][9][10]
In 2009, Snort entered InfoWorld‘s Open Source Hall of Fame as one of the “greatest [pieces of] open source software of all time”.[11]
