The Barracuda Spam Firewall optimizes performance of your email server while utilizing the following protections:

• Anti-spam
  

  The algorithms and methods used by the Barracuda Spam 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.

• Anti-virus
  

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

• Anti-spoofing
  

  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.

• Anti-phishing
  

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

• Anti-spyware (Attachments)
  

  All attachments are scanned and any spyware executables are detected and eliminated immediately.

• 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 Firewall.

End-user Control Features: User Based Filtering

• Individual Spam Scoring
  

  The individual spam scoring feature allows end-users to set their individual thresholds for spam tolerance providing personalized control over spam policies.

• Personal Allow and Block Lists
  

  The Barracuda Spam Firewall can be configured to allow end-users to have control over their individual allow and block lists which further reduces the chance of false positives.

• End-User Quarantine
  

  The Barracuda Spam Firewall provides the ability to setup quarantine mailboxes where users can direct questionable email for later review. This greatly reduces the support load for large organizations.

• Digest Emails
  

  A daily email is sent to all end-users with a quarantine account summarizing the contents of their individual quarantine mailboxes.

• Microsoft Outlook and Lotus Notes Integration
  

  Barracuda Networks provides a software plug-in for both Microsoft Outlook and Lotus Notes end-users. With this tool, users can classify messages as spam or not spam in order to fine-tune the filtering and further eliminate any chance of false positives.
