Hello, Is ISA 2006 a good enough software firewall to be used as a primary firewall on one of our Internet gateways? We use cisco asa 5505, Smoothwall Advanced software firewall and also a Watchguard x55e series deployed in various roles. I would like to deploy an ISA box to act as a primary firewall but would like confirmation that it will be safe or wise to do so. I have used it in proxy mode and is excellent at filtering out unwanted protocols/traffic etc as well as being great at creating routing policies etc.
How is it as a front line firewall?
Many Thanks, Aelara.
