Key Features
It's time to take control of spam! The Barracuda Spam Firewall is an integrated hardware and software solution that has the power of an enterprise-class solution, and the ease-of-use and affordability that businesses of all sizes demand.
The Spam Firewall includes the features you need to eliminate your spam and completely protect your email server from all forms of attack. Email may be blocked, quarantined, tagged, or delivered based on the policies of the organization or the preferences of the individual user.
Protection from Email Threats
The Barracuda Spam Firewall provides comprehensive protection against the most current email-borne threats that can cripple your network if left unprotected. With our proprietary twelve-layer defense system, the Barracuda Spam Firewall optimizes performance of your email server while utilizing the following protections:
- Anti-spam
The anti-spam 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.
- Anti-virus
By utilizing dual layer virus blocking, decompression of archives and file type blocking, the Spam Firewall anti-virus engine provides complete virus protection.
- 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.
Protection from Image-based Spam
In recent months, Barracuda Central has recorded a nearly 500 percent increase in image-based spam. In a large number of these cases, many of these images also contain text. Using OCR (Optical Character Recognition) techniques in combination with unique fingerprint methods, the Barracuda Spam Firewall has proven to be an effective protective force against image-based spam. Fingerprint analysis is capable of blocking image spam regardless of whether images contain text.
Barracuda Networks also developed methods to uniquely fingerprint components of spam messages, including images. Barracuda Central collects these spam fingerprints from honeypots as well as from thousands of Barracuda Spam Firewalls belonging to customers who opt-in to submit spam messages for analysis. Using this vast database of spam fingerprints, the Barracuda Spam Firewall’s new fingerprint analysis can profile message components of new spam emails against known spam fingerprints and automatically block, quarantine, or tag messages based on a match.
End-user Control Features
The Barracuda Spam Firewall features an easy-to-use Web interface, making management and administration of the appliance easy and cost effective. The Web interface allows you to define, manage and control corporate email policies from one central place.
- User-based Filtering
The Barracuda Spam Firewall can be configured to set spam policies by the end user on an individualized basis or on a global corporate level.
- 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.
Simplified & Centralized Administration
The Barracuda Spam Firewall features an easy-to-use Web interface, making management and administration of the appliance easy and cost effective. The Web interface allows you to define, manage and control corporate email policies from one central place.
- Multilingual User Interface
The Barracuda Spam Firewall features a user interface available in Chinese (simplified and traditional), German, French, Spanish, Japanese, Dutch and English.
- 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 Firewalls, which are automatically updated with new spam rules, spam algorithms, and virus definitions. These updates require zero administration and ensure that your network has comprehensive and accurate protection even as the methods of attack change.
- Logs and Graphical Reports
System administrators can view logs or generate graphical reports to provide visibility within the organization. The Barracuda Spam Firewall can generate reports on top email users, top spam recipients, top spam senders, and more.
- No Per User Charges
With the Barracuda Spam Firewall there are no per user charges so the system administrator no longer has to worry about keeping track of new accounts.
- Multiple Domains & Multiple Email Servers
A single Barracuda Spam Firewall can be used for multiple email servers and for multiple domains resulting in lower administrative costs.
Protection for Large Enterprises
The Barracuda Spam Firewall models 600 and 800 were engineered to meet the specific needs of large enterprises. These models offer all the scalability, redundancy and reliability needed for large-scale deployments at an affordable price.

The Barracuda Spam Firewall integrates with any IT infrastructure no matter how geographically or logically diverse.
- Clustering Multiple Barracuda
Spam Firewall models 600 and 800 can also be clustered for automatic scalability, redundancy and fault tolerance.
- Hot Swap Redundant Disk Array and Power Supply
These features provide a total solution for reliable fault tolerant data storage management necessary for large enterprises.
- Plug and Play Installation

- LDAP and Microsoft Active Directory Integration
Directory server integration allows for single sign on and recipient verification.
Deployment Configurations
The standard deployment configuration of the Barracuda Spam Firewall consists of a single email server and a single Spam Firewall appliance. Simply connect the Barracuda Spam Firewall to your network by assigning it a new IP address and changing your MX record to point to the Barracuda Spam Firewall.
Alternatively, you may also give your email server a new IP address and give the old IP address to the Barracuda Spam Firewall.
Multiple Email Server Environment
The Barracuda Spam Firewall supports multiple email servers and multiple domains.
Fault Tolerant Barracuda Spam Firewall Environment
For automatic scalability, redundancy and fault tolerance, you may cluster multiple Barracuda Spam Firewalls.
Multiple Email Server Location Environment
The Barracuda Spam Firewall can also be used in environments where there are multiple email server locations. For optimal performance, a Barracuda Spam Firewall should be placed in each location that contains an email server. This remote clustering capability can greatly simplify control and administration.
