To apply central usage policies and scan your web traffic for malware or unwanted content, forward web traffic to the Barracuda Web Security service, formerly known as FLEX, and configure your clients to use the Barracuda CloudGen Firewall as a proxy . The Barracuda Web Security Server is licensed on a per-user basis. If the number of users consistently exceeds the licensed number, traffic continues to be filtered, but you will be asked to upgrade your subscription to the actual user number. If the service expires, traffic is no longer filtered; it is only passed through.
