Not trying to make this a Cisco commercial, but I too am very satisfied with Cisco. We implemented an IDSM2, sensor device, and Cisco Security Agent for Host Intrusion Prevention. They all report into an easy to use central management location.

I have implemented a new cisco ids solution and i am very pleased with it! the signatures are highly tunable for a commercial package and it seems to be pretty stable. the sensor itself runs on redhat so maybe it isnt that much different than snort.

Hi Andy
How good can vendor independant IDS solutions (Specially Opensource) work in
an Enterprise Cisco Based network?
What do you think about Cisco IDS solutions?
Best Regards
Mit freundlichen Grüssen

Hi Mat,
I was faced with the same dilemma some years back, my site below details the
various technologies you can bring to bear. I also wrote an article for
SecurityFocus regarding deploying IDS from a vendor neutral standpoint
http://www.securityfocus.com/infocus/1754
I'd suggest starting simply and building up but always keep the defence in
depth end goal in sight. Also, don't forget that in addition to detecting
attacks you have to react to them also. If you need further advice offlist
don't hesitate to ask.
Finally, if you go down the Network IPS route there are 2 main varieties;
rate based and content based, I refer to the former as Attack Mitigation
Systems they fill an important role but IMHO are not IPS. Ideally you
should have both varieties. There are some products that claim to do both,
but .....
take care
