Commercial IDS Appliances Built on Snort

Consider all of the commercial IDS appliances built on the Snort detection engine:

• Sourcefire Network Sensor


• Silicon Defense Sentarus


• PacketAlarm


• StillSecure Border Guard; check the FAQ -- they run Snort but hide it well


• Argus 1000; no relation to the one true Argus


• FidelisSec CyberHound

Snort isn't the only open source IDS engine in town. Check out Shoki or Tamandua.
