NeVO does two things for you.

First, it finds out your vulnerabilities passively so that
the Lightning Console can do correlation between those vulns
and events from Snort, ISS, Dragon, .etc.

Second, NeVO looks for likely compromises in the applications
it detects. It's not a signature or anomaly system. Think of
doing the sort of IDS/VA correlation that SIMs do, right in
the actual sensor. Customers of ours that run NeVO and one or
more NIDS receive 1000s of times more alerts than what they
get with NeVO.
