Spam and Virus Protection from our Barracuda Spam Firewall

The Barracuda Spam & Virus Firewall provides comprehensive protection against the most current email-borne threats that can cripple your network if left unprotected. With the Barracuda Networks proprietary twelve-layer defense system, the Barracuda Spam & Virus Firewall optimizes performance of your email server while utilizing the following protections:

  • Internet

  • Multiple Barracuda Spam & Virus Firewalls

  • Email Server


The algorithms and methods used by the Barracuda Spam & Virus Firewall are the most comprehensive and most advanced in the industry at detecting and filtering spam resulting in the lowest rate of false positives. Barracuda Networks Predictive Sender Profiling looks beyond the reputation of the sender and digs deeper into the spam campaign itself to identify anomalous activity.


By utilizing triple layer virus blocking, decompression of archives and file type blocking, the anti-virus engine in the Barracuda Spam & Virus Firewall provides complete virus protection. When new spam and virus outbreaks occur, Barracuda Real-Time Protection will block these threats in real-time.


The Barracuda Spam & Virus Firewall provides robust protection against phishing schemes which are often used to gather confidential information about an organization or its individual users.

Denial of Service Protection

Rate controls are utilized to stop denial of service attacks as well as dictionary based spam attacks. These rate control systems are integrated and automatic in the Barracuda Spam & Virus Firewall.


This technology prevents the use of forged or "spoofed" sender addresses on unsolicited email. The anti-spoofing feature also allows larger organizations to specify a list of IP addresses that are allowed to have a "From" address that appears from inside the organization to support multiple sites and multiple email servers.


(Attachments) - All attachments are scanned and any spyware executables are detected and eliminated immediately.

Barracuda Energize Updates. A team of security engineers at Barracuda Central continuously monitors the Internet for trends in spam and virus attacks. As they detect trends, Energize Updates are created and distributed to all Barracuda Spam & Virus Firewalls, which are automatically updated with new spam rules, spam algorithms, and virus definitions every hour. These updates require zero administration and help ensure that your network has comprehensive and accurate protection even as the methods of attack change.
