One that seems to be pretty good is Network Flight Recorder (
http://www.nfr.com ). This can run on an affordable Intel or Sparc box,
and for internal private use, it's free (and somewhat limited in speed).
There are also some (free) modules for it at loPht ( http://www.L0pht.com
-- make sure you get L"zero"pht.com, or you'll get a nice surprise).
NFR is a general-purpose platform for network analysis and reporting, but
it seems that right now it is most well-known for security analysis and
detection. The cool thing about it is that you can write your own modules
(that's one of the intents of the samples at L0pht.com).
