A zero-day exploit is a curious marketing thing. You suddenly redefine a
difficult problem (catching zero-days) as a rather simpler problem
(create signatures that actually describe the vulnerability, which is
what any signature worth your licensing cost should do).

So, presto!, you can rush up and put out some rather nice marketing
material on it.

Fact is, anomaly detection is so rare that it's almost unexistant in the
commercial products, except for limited forms of "protocol anomaly
detection" and for Arbor's peakflow technology.
