About the Barracuda Spam Firewall

The Barracuda Spam Firewall is available in five models and supports from 1,000 to 30,000 active users with no per user licensing fees. The Barracuda Spam Firewall can be installed in front of the email server in typically less than five minutes and is automatically updated hourly to block new forms of spam and viruses. Its architecture leverages open source spam and virus solutions in conjunction with ten defense layers: denial of service and security protection, IP block list, rate control, virus check with archive decompression, proprietary virus check, user specified rules, spam fingerprint check, intention analysis, spam rule-based scoring, and Bayesian analysis. This architecture 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. Barracuda Networks also offers the Energize Update subscription service to automatically update the Barracuda Spam Firewall with the latest spam rules and virus definitions.
