I am losing my Cisco gear and it is being replaced with another manufacture (long stories not really relevant) so I am looking for something that can replace my NAM. So far i have found a few companies that make these types of stand alone appliances for packet captures, Niksun (NetOmni), Riverbed (SteelCentral),Netscout, and Savvius Omnipeek. Anyone have experience with these companies products or know of others i can check out?
