IBM Proventia GX6116

The Proventia IPS GX6116 could be considered the high-end sports car of IPS appliances. Not only does this device include several protection and analysis features, such as protocol analysis for more than 140 different network and application protocols, heuristics and pattern matching, but it is built for speed. This appliance includes a top-spec network processing unit, as well as eight 64-bit multi-core processors and dual Xeon x86 processors examine traffic across all seven OSI layers. This beast of a box can handle almost any amount of traffic thrown its way and still have resources to spare.
