Mike,

The free trial is the paid version right? Just was wondering if you use the
community or advanced paid version.

I had intended to use the paid version once the 'free trial' proved to
work, but for the previously mentioned reasons it did not and I gave up.
Would still love to have this style of solution in my network and still
open to other solutions, just haven't really found anything else.

Mike,

What did you end up going with if not fastnetmon? Were you using
their paid or free version?

FastNetMon is awesome, but its a detection tool with no mitigation

Does is not, though, provide the ability to hook into RTBH or Flowspec
setups?


Yes it does provide RTBH hook.

I evaluated fastnetmon using exactly the 'quick setup' and found it to
have some serious problems with false alarms and statistical anomalies,
at least when using pure netflow data (did not try sampled mode).  Hosts
that were not in fact receiving >100mbps traffic (a traffic level I
predetermined as 'attack' for a given network segment), would
occasionally get flagged as such (and rtbh activated), while 2 real
attacks that came during the testing period (60 days for me) went
completely unnoticed. Support seemed to concede that sampled mode is
really the only accurate method, and which by this time I'd expended all
my interest. Great concept, cool integration, just not ready for prime
time.


MIke-
