RE: Network hardware IPS

["Bob Walder" <bwalder () spamcop net>]

Well inasmuch as the report is not ready RIGHT NOW this is probably not
what you want to hear... But.... We are currently testing a whole bunch
of these IPS doohickeys and the report - including exactly the test
results you are seeking (amongst many others), will be published in
December.

In the mean time, check out our latest IDS reports at www.nss.co.uk/ids
and www.nss.co.uk/gigabitids

Bob Walder
Director
