Barracuda Spam Filter Review

Posted on Aug 13 2010 - 11:42am by gchoe



If you are ready to get past software solutions to filter spam and viruses and set up a firewall you may want to take a look at Barracuda networks.  They have the most widely used spam filtering appliance and are generally well respected.  With that said, read on to see what we thought of our time with our Barracuda spam filter.

We maintain our own email server and have always battled with spam, viruses, and general firewall security.  After reading online about the Barracuda spam filter online we decided to give it a try.  One of the obvious advantages of the Barracuda spam firewall is that it sits in front of our email server saving us time, headaches, and server bandwidth.  The box is clean and fits in a 1U rack slot, even has some pretty lights.

After the Barracuda spam filter was put in the rack and configured with the basics, it was pretty easy to get started with a basic configuration.  Once you are past the obvious IP configurations and have it added to your network you can manage it remotely via a web interface.

Barracuda Spam Virus Firewall Architecture

The anti spam appliance lets you set rules as to what should/shouldn't be allowed to flow to your email box.  You have bayesian filtering and a local database of past email habits which improves over time.  The spam filter checks email headers, email subject, reverse DNS lookups, and more. 

The main dashboard page of the Barracuda spam firewall interface has a clean easy to read layout with nice graphical bits.  This eye candy tells you stuff like the number of emails filtered, percentage of good versus spam emails, etc.  You will quickly know more about your spam levels than you have ever wanted to know. 

We had almost no false positives (the few we did have were well deserved) and with minimal tweaking were confident the box was blocking spam and viruses.  All-in-all we are happy with the Barracuda spam & virus firewall filter, our only gripe is the price tag.  (there are too many versions to discuss pricing at the moment, you can see some options here.)
