We're actually working an IPS here. It's home grown, so it's a bit of a
mess, but we've taken SNORT and the Bleeding SNORT rule set, refined it
with a lot of custom written rules and a very custom config. We use
that as a basis for the IPS. Based on the alerts, we have custom
scripts that temporarily adds rules to the FW and ACL's to the core
router. So far, we've had some false positives, but overall it works
well. It's also written in Perl.
GUI interface - HAH!
Error Messages - ROFL!
Functionality - two thumbs up!
Flexibility - About like this -

False positives is one, the algorythms used to scan traffic is another,
un-flexibility is another big one.
Most of these problems are easily solved except for when you make a
commercial product you have to "dumb it down" so the end users can
handle it. I'm designing an IPS for a large customer whom we all know
and you would figure these people should know it all. I have to put
miles of if statements in the code with accompanying error messages to
describe why you cant do this or that. When we can open up the throttle
and not worry about the end user we can have some awesome stuff on the
market. Take "vi" the text editor for example. To a newb it's terrible
but to someone who's used to it it's a necessity. Most of the truly
useful features in these products wind up on the cutting room floor
because the decision makers don't want to do it for money or time
constraints. To tell you the truth your better stuff is coming from
smaller companies and not symantec, cisco, etc... Anyone who begs to
differ works for one of the said companies. The executives keep tight
leashes on the development departments.
