Independent network device dedicated to spam-blocking
The Barracuda Spam Firewall is a self-sufficient networking device that handles all your spam-blocking so it does not bog down your email servers. In fact, with the Barracuda Spam Firewall, the load on your email system is actually reduced. Your email servers will process and store less incoming email. The performance of your email servers will increase.

Blocks spam using proven methods
By using all the best methods to block spam, the Barracuda Spam Firewall provides comprehensive spam-blocking for your company. Below are the primary algorithms employed to block spam. Barracuda Networks generally recommends targeting approximately 97% blockage. However, a number of parameters are provided for adjustments if necessary.

  • Blacklisting of websites & domains: Barracuda Central maintains an up to date list of the largest and most aggressive known spammers. This list is maintained by both Barracuda and other anti-spam groups. This list is automatically updated on each Barracuda Spam Firewall.
  • Keyword scanning of emails: This can be configured on a per user basis. The scanning methods include a scoring system such that emails are scored based on a number of criteria. If the score is above a threshold, then that email is flagged as spam. The Barracuda Spam Firewall comes with default criteria and thresholds but you may change these.
  • Checksum technology: Barracuda Central monitors email traffic through the Internet and uses checksum technology to keep track of the number of times a particular message has appeared on the Internet. If a message has appeared over a certain number of times, it is categorized as known spam. Checksums of known spam messages are utilized by the Barracuda Spam Firewall to block spam messages.
  • Message authenticity checking: Several algorithms are utilized to verify the authenticity of a message. Some of these are simple checks to verify that the "from address" is authentic. Some are more complex relating to SMTP protocol.
  • Blacklists and Whitelists: Domains, IP's, and email addresses can be blocked or whitelisted (allowed through). These lists may be maintained on a per user basis or on a corporate basis.
  • Rate controls: Utilized to stop denial of service attacks as well as dictionary based spam attacks. These are integrated and automatic in the Barracuda Spam Firewall.
  • File type attachment blocking: You can block certain types of files, such as vbl scripts, from entering your company.

User-based and corporate-based filtering
The decision on what types of emails to block can be made either at the end-user or at various corporate levels. You have the flexibility to decide where you'd like the decision to be made.

Suspect emails get quarantined
There are three main types of emails: emails that you want, emails that you do not want (spam), and emails that are suspect. The Barracuda Spam Firewall can tag suspect emails for delivery into a separate folder. You can then either have the end user or another designated person be the final judge of what to do with these suspect emails. If after 30 days no action is taken, the message is deleted.

Optional bulk mailboxes for users
Barracuda Spam Firewall provides optional bulk inboxes so that users can direct spam messages straight into these areas. This prevents spam from cluttering up their main mail system. These bulk email boxes can be checked periodically or ignored.

Automatic system updates
A team of engineers work at Barracuda Networks' special operations center, Barracuda Central, to monitor the Internet for trends in spam and virus attacks. As they detect trends, updates are created for the Barracuda Spam Firewall. Your Barracuda Spam Firewall can then automatically update itself without any intervention. There is no need to retrieve anything. No need to tune anything. Maintaining your Barracuda Spam Firewall to deliver maximum protection is that easy.

Logs and reports on email statistics
System administrators can view logs or generate reports at any time from the desktop. It's quick, easy, hassle-free administration.
