Are there unified threat management (UTM) firewalls with the chops to provide the perimeter security functions that an enterprise needs?
There is no real agreement about whether antivirus software is required in or even a good idea for an enterprise-class firewall.
The data center may seem a big place, but watts are watts: Every one you use costs you money. Two firewalls in a high-availability pair may not be the biggest power expense in a computer room, but that's no excuse to waste wattage.
We tested the OSPF-routing capabilities of the UTM devices in order to simulate the kind of multiple-exit network (two Internet gateways) that might be common in a large network.

Nearly a year ago, Microsoft released Office 2007 to corporate users and so began the slow and methodical evaluation of the software (unless, of course, you were an early adopter).
