Would have to agree with this, if you need to use and properly control
some sort of RPC based application then ISA all the way, the RPC
manageability is unchallenged by any other firewall.
Like Jim said, look at the traffic carefully and decide what you need.
ISA and CP whilst excellent products might be overkill for your
requirements and something smaller might be useful.
It's worth noting that you can get ISA as an Appliance, but personally I
generally steer clear of appliances, for the following reasons:
Upgrade usually means entirely new box and often another software
Patch management doesn't generally fit in with other systems, since the
boxes usually have their own process.
Also most of them have a very powerful operating system underneath which
is only exposed to you via a limited interface. For example Borderware
has an utterly useless interface but is a FreeBSD system at it's core
and it pretty much runs on standard PC hardware (it comes with a DVD
My only argument for appliances is "Nokia boxes look cool in a rack".
