I have been at this for a while, researching and trying to figure out what is overkill, what is not enough. Here are my companies needs:
We have 20-25 users connecting to the internet, most are wired however some are wireless. The most important aspect of the firewall is the content filtering/URL blocking etc. I have found plenty of firewalls that do this, but it seems that there is always overkill or no group policies. I want to be able to set up group policies for the users. For example, Managers can have more access than our regular employees who will be more restricted. Also, it would be nice to have some sort of log to view which computer is accessing what.
I looked at Sonicwall and Watchguard, but they seemed to be too much or had too many subscription services for what I wanted. I wouldn't mind some virus scanning capabilities, but Sonicwall requires that you have McAfee installed on the client computers and frankly, I've had bad experience with the McAfee clients so I'd rather not go there.
From another question on EE, I checked out the ZyXEL ZyWALL 5 UTM appliance, but once again, it may be overkill for just 20-25 users. From what I could tell, it did not have group policies, but it at least had "excluded"IP addresses, which I could do.
Anyone have any suggestions on what would be a better appliance to look for? I would like it to have WiFi capabilities so I can cut down the appliances from 3 to 2 ( Currently am running a Linksys router and a Netgear attached to it as an AP)
