If you have concern over the type of traffic going over your network StenGuard
is an affordable way to track it.
Set up a dictionary of words or phrases to track in StenGuard and it will
"sniff" every packet and log every hit. When the value for a specific watch word
is hit an email report will be generated and sent by email. Includes HTML scan
functionality as well as live network monitoring watching such things as logged
on users, services, event logs, etc. A 3D performance monitor is also available.
