We've been using Bradford's product, and are moving to Perfigo as part
of a system-wide directive from above. I'd like to add my 2 cents...
Nessus IS a good tool. However, we're seeing more and more computers
these days with firewalls running. Either Windows Xp SP2, or even the
latest anti-virus packages often have them running. Nessus can't scan
them, and a firewall in no way makes for a secure station. I've never
checked the percentage of the student population with firewalls, but it
is certainly growing, so anything Nessus based is going to have short
legs and is going to miss a lot of computers with issues.
If I were going to look for a new solution, I'd be looking for the
Preferably 802.1X based, so the authentication can be off-loaded to the
Definitely requiring some sort of a client agent, as that's probably the
only long-term solution.
In terms of what's out there-
Bradford's product does do VLAN switching, which is good. But is Nessus
based. Although we do have the product coupled with an IDS, which does
do a good job of detecting ad shutting down the worst of the rogues.
Netreg is also Nessus based, doesn't do any switching, and unless you
have some good scripting set up, can be thwarted.
Perfigo is in-line, in my opinion primitive, and owned by my least
favorite company, but does have an agent at least.

We want to go further than netreg in the quarantine department. We
don't want students on the same VLAN until they are safe so we will
manipulate the switches (as we currently do by hand). We have most of
that part already figured out but want to decide what to scan with. We
are considering nessus. VERY good to see some of you are using it for
