I'm trying to find reviews and ratings on various firewalls. I install a lot of firewalls in small businesses. A lot of my customers have Microsoft Smalll Business server so they are hosting their own email server. They do not have personal data to protect such as SS# and bank accounts so they don't need Cisco or Checkpoint firewalls.
I'm looking to find out if all the low end firewalls such as Linksys, Sonicwalls, and Watchguards are equal when it comes to security. I know that various Firewalls have different features such as spam and antivirus filters, log files and filtering by web sites etc.
Is there a place that compares these firewalls and list the features that each has?
I'm also trying to find the least expensive firewalls that support multiple public IP addresses.
