Barracuda Networks Spam Firewall 600 BSFI600A Leaflet

Powerful, easy to use, and affordable enterprise-class spam and virus protection.

The Barracuda Spam Firewall is an integrated hardware and 
software solution designed to protect your email server from spam, 
virus, spoofing, phishing and spyware attacks. The Barracuda Spam 
Firewall is compatible with all email servers and can fit into nearly 
any corporate or small business environment.  With no per user 
license fees, the Barracuda Spam Firewall offers the most 
affordable  enterprise-class spam  and virus protection available.

A single Barracuda Spam Firewall supports up to 30,000 active 
email users. Multiple Barracuda Spam Firewalls can be 
clustered for greater capacity and higher availability. 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.

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. Its architecture leverages 12 comprehensive 
defense layers to provide industry-leading defense capabilities.
