Features & Benefits of Barracuda Spam & Virus Firewall

Reduced Spam

Today's effective email security has reduced the volume of spam worldwide by half. However, spam is still a nuisance and the sophistication of email attacks has grown. For example, criminals are using email addresses stolen from databases using SQL injection attacks to launch targeted spear-phishing attacks against email users. Today, email security must deliver state-of-the-art protection with minimal management burden. Due to concerns about data loss prevention and regulatory issues, email encryption is also a must for most organizations.

The Barracuda Spam & Virus Firewall integrates the advanced technology needed to detect known and new attacks and provides email encryption at no added cost. Backed by Barracuda Energize Updates, the Barracuda Spam & Virus Firewall adapts to new threats with the fastest response times in the industry. The Barracuda Spam & Virus Firewall also offers a wide variety of settings for custom tailoring email security, administration and content policies to a broad set of special requirements.

Email Security

The Barracuda Spam & Virus Firewall provides comprehensive protection against email threats. Using twelve layers of security technology to keep malware, fraud and junk traffic out of network links and email servers, the Barracuda Spam & Virus Firewall also optimizes email server performance. Here is some more information about this solution's security features:


The Barracuda Spam & Virus Firewall provides robust protection against phishing attacks. Barracuda Anti-Fraud Intelligence is a targeted layer optimized to detect and block advance-fee fraud and other types of phishing emails.


The Barracuda Spam & Virus Firewall's algorithms and other detection methods are the most accurate in the industry for filtering spam and giving the fewest false positives. Predictive Sender Profiling directly analyzes spam campaigns to identify anomalous activity.


This feature prevents the use of forged or “spoofed” sender addresses on email. The anti-spoofing feature also lets organizations create a list of IP addresses in the organization that are allowed to have a “From” address that appears to support multiple sites and multiple email servers.

Attachment Anti-spyware

This feature scans all attachments for spyware. If spyware executables are detected, they are instantly eliminated.

Denial of Service Protection

Rate control automatically stops denial of service (DoS) attacks and dictionary-based spam attacks.

Directory Harvesting Protection

Running in parallel with rate control, directory harvesting protection sets a limit on the number of invalid requests received before an IP address is blocked.

Managing User Accounts

The Barracuda Spam & Virus Firewall provides several features for managing user accounts including features that let users fine tune their own accounts.

User-Based Filtering

Administrators can configure spam policies for individual users and global users.

User Quarantine

This feature gives users quarantine mailboxes where they can direct questionable email for review.

Individual Spam Scoring

The individual spam scoring feature lets users configure their own spam-tolerance thresholds.

Digest Emails

For users who have a quarantine account, this feature sends a daily email summarizing the contents of their quarantine mailboxes.

Personal Allow and Block Lists

The Barracuda Spam & Virus Firewall can be configured to let users control their own allow and block lists to reduce false positives.

Microsoft Outlook
and Lotus Notes Integration

A software add-in for Microsoft Outlook and Lotus Notes lets users classify messages as spam to adjust filtering. The Outlook add-in can also mark emails for encryption.

Intuitive Appliance Administration

The Barracuda Spam & Virus Firewall's intuitive web UI streamlines appliance management keeping labor costs low. The web UI provides clear visibility into email activity while granting fine-grained control over security, content policies and a host of other configurable features.

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, they create Energize Updates and distributed them to Barracuda Spam & Virus Firewalls, which automatically update with new spam rules, spam algorithms, and virus definitions. These updates require no administration while ensuring that your network has comprehensive and accurate protection even as attacks evolve.


The Barracuda Spam & Virus Firewall supports message archiving. When a value is specified for a journaling destination address, a copy of all email sent through the Barracuda Spam & Virus Firewall is forwarded to that address.

Monitoring and Reporting

The dashboard in the intuitive web UI gives administrators an instant snapshot of email and threat activity as well as system performance. For forensic analysis and discovery purposes, the Barracuda Spam and virus firewall logs email. These logs can be quickly filtered and exported. Reports are easy to schedule for automated creation and emailing to selected personnel. The Barracuda Spam & Virus Firewall can generate reports on top email users, top spam recipients, top spam senders and more with no database administration required.

Role-Based Administration

Barracuda Spam & Virus Firewalls support four levels of role-based administration: User, Helpdesk, Domain Admin and Auditor. Assigning and editing administration roles takes a only few moments through the web UI.

Independent Inbound and
Outbound Policies

Setting up separate filters on inbound email traffic and outbound email traffic for security and content policy enforcement is quick and easy through the intuitive web UI.

No Per-User Charges

With the Barracuda Spam & Virus Firewall there are no per user charges so administrators don't need to keep track of new accounts.

Multiple Domains and Email Servers

A single Barracuda Spam & Virus Firewall can be used for multiple email servers and for multiple domains resulting in lower administrative costs.

Protection for Large Enterprises

With intuitive central management of Barracuda Spam & Virus Firewalls at multiple locations and appliance models scaled from the largest central headquarters to the smallest satellite locations, the Barracuda Spam & Virus Firewall is purpose-engineered to meet the needs of large enterprises.

Central Management

The Barracuda Control Center is a cloud-based portal that makes managing multiple Barracuda Spam and Virus Firewalls simple and straightforward. Use of the Barracuda Control Center is included with Barracuda Spam & Virus Firewalls at no added cost. A hardware version of the Barracuda Control Center is available for purchase.

Plug-and-Play Installation

Deploying the Barracuda Spam & Virus Firewall is very straightforward with no software to install or modifications to make on your email systems.

Data Loss Prevention and Encryption

Data Loss Prevention features ensure that no confidential information leaks out of the organization. Any sensitive information that needs to be sent via email can be encrypted using the features available in all models of Barracuda Spam & Virus Firewall.

Email Encryption

Administrators can create policies that specify encryption for certain types of outbound emails. Policies can also be created to let users encrypt their own emails. Email encryption is done using the Barracuda Message Center, a cloud-based portal that solves the problem of key exchange.
