What do you use for a network wide firewall?

Hi all,

To those of you who are facilites based, what do you use for a network wide firewall? We have in the past only used host based firewalls but we are growning enough and offering enough services where we would like to put a firewall at the edge and filter/check all traffic coming in for issues, intrusion prevention etc.

So our task is to find a good, but economical firewall to deploy to handle multi megabit traffic (not gigabit yet).

Would anyone like to share how they do it and any hardware, appliance applications?

Thanks,

Rob
