I think there's more here than most comments reflect - yes, this is being done in many implementations today, but not nearly as efficiently. 4W for 1Gb of DFA stream analysis? That's pretty crazy considering that can put full on content inspection in a SOHO device that can end up in consumers networks. DFA is the shift from file based scanning in network security and offers parallelism efficiencies far beyond most of the UTM type platforms out there today. There are only a few companies using stream based platforms (Palo Alto Networks is one) and this is why the platform can do much more content scanning in one pass vs the legacy devices.

But, this is killer for SOHO networking IMHO. Puts a ton of power into the next wave of network security.
