My little spot on the Internet about server colocation
Barracuda firewalls have no trouble fitting into networks both large and small and work well with all types of email servers. Just one Barracuda firewall easily handles 100,000 users, and several Barracuda firewalls can be grouped together for service to an even larger group of users. No modifications need be made to your current email system and no software need be installed when adding a Barracuda firewall to your network. Your Barracuda firewall can be up and running within minutes. Once the system is installed, the intuitive web interface contained in the Barracuda firewall monitors, maintains, and updates itself in order to keep one step ahead of the latest Internet threats.
