RE: Recommending an IDS system

I did an evaluation with Sourcefire and I have to say that I really liked
it.  We are doing evals on other appliances before committing to anything.

Sourcefire has three architectures to choose from; IBM, Intel, and Solaris
(IIRC -- they might not have a solaris product but I believe they do).  We
went with the Intel 22mb arch since it was the least expensive and our
infrastructure doesn't require much hardware-wise to watch whats going on.
Each architecture also has a speed associated with it which for higher
speeds you'd pay more for the product.  The speeds were (again, IIRC) 22mb,
45mb, 100mb, and 1gb.  These speeds were the amount of throughput that the
snort engine was tuned to be able to watch without dropping packets as well
as hardware for the gigE interface, I believe.  They have a configuration
management machine that is capable of monitoring all of the sensors on your
network allowing administrators to view all goings-on from one central
location.  That machine is a flat $17K.  It is not a sensor.  You can't eval
that machine either so it is difficult to say how well the product will do
its job.  However, judging on the appliance and its abilities the config
mgmt box is probably decent.

We started the evaluation using the older 2.7 interface.  The 3.0 interface
went prod while we were eval'ing the unit so I upgraded the machine from 2.7
to 3.0 which was an extremely simple process.  I found the 3.0 interface to
be 100x's better than the 2.7 interface.  Out of the box the configuration
of the product was simple.  Tuning is the same as any other IDS.  It was
basically plug-n-play, though.  You can update the snort rules, which come
from Sourefire, from the web interface.  You also get full admin access to
the console of the machine should you decide to mess with things or want to
view logs or whatnot.  It was not necessary to ever really use the CLI,
though.

Overall, I really liked the product.  We are evaluating the Still Secure IPS
product now.

Does anyone have any insight into the Sourcefire products?  They are Linux 
appliances  based on the Snort system.
