The Barracuda Spam Firewall is compatible with all email servers and can fit into nearly any corporate or small business environment. It is used by small organizations with as few as 10 employees and large organizations with as many as 200,000 employees. A single Barracuda Spam Firewall handles up to 30,000 active email users. Multiple units can be clustered together for even greater capacity and high availability.

The Barracuda Spam Firewall architecture optimizes the processing of
each email to maximize performance and 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.
In addition, all Barracuda Spam Firewall models include essential
outbound filtering techniques including attachment scanning, virus
filtering, rate controls and encryption. These features help
organizations to ensure that all outgoing email is legitimate and
virus-free.
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. With Barracuda
Networks Energize Updates, the Barracuda Spam Firewall is continuously
updated with the latest spam and virus definitions every hour keeping
maintenance to the unit at a minimum and eliminating administrative
overhead. Updates are provided by Barracuda Central, an advanced 24/7
security operations center that works to continuously monitor and block
the latest Internet threats.
At Barracuda Networks, we design and build products not only for
their power and ease of use, but also for their affordability. With no
per user license fees, the Barracuda Spam Firewall is the most
affordable enterprise-class spam and virus solution available.
