Barracuda Spam Firewall
The Barracuda Spam Firewall is an integrated hardware and software solution for complete protection
of your email server. It provides a powerful, easy to use, and affordable solution to eliminating spam
and virus from your organization.
A single Barracuda Spam Firewall handles up to 25,000 active email users and 25 million email
messages per day. The Barracuda Spam Firewall is a powerful, enterprise-class solution. Multiple
units can be clustered together for even greater capacity and high availability.

The Barracuda Spam Firewall design leverages open source virus and spam solutions in conjunction
with ten defense layers:
• Denial of service and security protection
• IP block list
• Rate control
• Virus check with archive decompression
• Barracuda virus check
• User-specified rules
• Spam fingerprint check
• Intention analysis
• Bayesian analysis
• Rule-based scoring
The Barracuda Spam Firewall architecture optimises the processing of each email for the performance
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.
With no software to install and no modifications required to existing email systems, installation of the
Barracuda Spam Firewall is quick and easy. Once installed, the system administrator uses the intuitive web
interface for monitoring and maintenance. Maintenance is minimal, especially with the help of Energize
Updates. These updates, automatically retrieved by the Barracuda Spam Firewall, enable maximum spam and
virus protection at all times while eliminating administrative overhead. Updates are provided by Barracuda
where engineers monitor the Internet for trends in spam and virus threats.
Barracuda products are not only designed for their power and ease of use, but also for
their affordability. With no per user license fee, the Barracuda Spam Firewall is the most affordable
enterprise-class spam and virus protection solution available.
