Ugh.

Mark, for the love of god, please don't do the 0 thing when referring 
to Snort. :)
Certainly ISS site protector is an attempt to be many things to many 
people.  However, in its attempt to do so it missed one key ingredient: 
the ability to do any of those things sufficiently fast enough for a 
deployment requiring scalability of alert handling.  Presupposing a 
centralized alert console performs post-processing of data, the need to 
accept high data rates is for all intents and purposes, a firm 
requirement.
Whether or not a company approved of the use of Snort before they 
purchased Sourcefire products, the irony is that they certainly 
approved of them (in some way) after purchasing them. :)
