The Barracuda Spam Firewall is available in six models capable of supporting from 1,000 to 30,000 active users with no per user licensing fees. Typically, Barracuda Spam Firewalls can be integrated into a network in less than five minutes and immediately begin receiving automatic hourly updates that enable these devices to block new and evolving forms of spam and viruses. The spam firewall architecture provides spam protection with 12 defense layers including denial of service & security protection, rate control, IP analysis, sender authentication, recipient verification, virus protection, user-specified policy, fingerprint analysis, intent analysis, image analysis, bayesian analysis, and a spam rules scoring engine.

The entire Barracuda Spam Firewall line features simultaneous inbound and outbound email filtering with the inclusion of sophisticated outbound email filtering techniques, such as rate controls, domain restrictions, user authentication (SASL), keyword and attachment blocking, dual layer virus blocking, and remote user support for outbound email filtering.

The Barracuda Spam Firewall's layered approach minimizes the processing of each email, which yields the performance required to process millions of messages per day. Unlike software solutions, the Barracuda Spam Firewall reduces the load placed on the email server by off-loading both spam and virus filtering. Updated spam rules and virus definitions are provided by the Barracuda Networks Energize Update subscription service - ensuring protection from the latest threats.
