Adriel,

D-Link and Netgear are no references, only products that have IDS or a
little part of IDS function.
IPCOp also has this Function, and Watchguard on the new product "Fireware
Pro" also ad an proactive service AV/IPS.
Micro Liss FL II320  from Telco-Tech also have an IDS.
I don't say that an IDS is the one and only.
But Sebastian Schreiber from SySS (Germany) have shown that an Firewall
only could be leak.
