Barracuda Email Security Gateway 100 Features
With a long-standing heritage in spam protection, Barracuda Networks remains the leader in identifying and blocking spam. A comprehensive set of security layers ensures that organizations remain productive in the face of evolving threats.
The Barracuda Spam Firewall 100 leverages Barracuda Central to identify email from known spammers and determine whether domains embedded in email lead to known spam or malware domains. It leverages many of the same industry-leading techniques found in the Barracuda Spam Firewall that protect against attempts to embed text inside images with the intent of hiding content from traditional spam filters.
As virus attacks become more sophisticated and complex, email infrastructure requires advanced virus protection. The potential for the destruction and release of information, or the disruption of a network severely impacts productivity and can lead to financial loss.
The Barracuda Spam Firewall 100 scans email and incoming files using three powerful layers of virus scanning technology. It also decompresses archives for complete protection. Powerful virus definitions are automatically updated via Energize Updates to maintain the most up-to-date protection against email-borne viruses.
To provide protection from tainted internal email, a Microsoft Exchange Plug-In allows organizations to protect against the spread of viruses that don’t access the email gateway. The virus definitions are also regularly updated to ensure the latest protection.
All Barracuda products are supported by Barracuda Central, a 24×7 advanced security operations center that works continuously to monitor and block the latest Internet threats. Barracuda Central collects data from more than 150,000 collection points worldwide and analyzes it to develop defenses, rules, and signatures. As new threats emerge, Barracuda Central is quick to respond to early outbreaks and delivers the latest definitions through Barracuda Energize Updates. These updates require zero administration and ensure that the Barracuda Spam Firewall provides comprehensive and accurate protection against the latest Internet threats.
Denial of Service (DoS) Attack Protection
Not every attack is focused on getting users to send their credit card number, getting users to click on a malicious link, or to plant a virus. Often, the objective of the attack is focused on disabling a network or mitigating its effectiveness. As a cloud-based service, the Barracuda Spam Firewall is positioned to stop spammers before they overload an email server.
The Barracuda Spam Firewall 100 ensures that email can still be delivered even during email server failures or loss of connectivity. In the event of on-premises disruptions, email can be spooled in the Cloud Protection Layer for up to 96 hours. An alternate destination can also be specified for delivery, if delivery to the primary destination fails.
During email server outages, the email for all mail servers is visible through the Cloud Protection Layer. From the message log, you can see the status of all spooled emails, and whether mail has been re-delivered.
Spam and Virus Pre-Filtering
The Barracuda Spam Firewall 100 is integrated with a cloud-based service that pre-filters email before delivery to the on-site Barracuda Spam Firewall. The Cloud Protection Layer is continuously updated with definitions in real time with updates from Barracuda Central. The elasticity of Barracuda’s global cloud infrastructure provides the flexibility to handle email surges during specific periods of the day and during Denial of Service attacks.
The Cloud Protection Layer ensures that an organization’s email security infrastructure scales with the increasing growth in email volume and attachment sizes; as well as the growth of companies. By leveraging the bandwidth and computing power of the CPL, organizations can easily scale their email security solution.
The Barracuda Spam Firewall 100 offers a number of encryption features. It is fully integrated with a cloud-based email encryption service for outbound email. Email that matches policy or are marked for encryption via the Barracuda Outlook Add-in are securely sent via TLS to the Barracuda Message Center.
The Barracuda Message Center uses AES with 256-bit keys to encrypt email. To encrypt email traffic between sites over the Internet, the Barracuda Spam Firewall Message Transport Agent supports SMTP over TLS. This can be used between Barracuda Spam Firewalls or other email servers that support SMTP over TLS.
Outbound filtering prevents organizations from being put on spam block lists and prevents sensitive data in email from leaving the organization. Employees can inadvertently cause internal systems to become a source for botnet spam. Using a subset of its defense layers, the Barracuda Spam Firewall’s outbound filtering stops outbound spam and viruses. It also lets administrators enforce content polices for data loss prevention (DLP) and to meet other content standards in outgoing email. Predefined filters and custom policies can be used to detect sensitive data and block or encrypt email.
Cloud-Based Central Management
The Barracuda Spam Firewall 100 is integrated with the Barracuda Cloud Control (BCC) web-based management portal, which leverages Barracuda’s global cloud infrastructure to enable organizations to centrally manage all their devices through a “single pane of glass” interface.

Barracuda Spam Firewall FAQ:
Why did Barracuda Networks change the name of the Barracuda Spam Firewall ?
Barracuda Networks is adding new emphasis to its purpose-built anti-virus engine for email and Web threats. Unlike desktop anti-virus engines retrofitted for gateway use, the Barracuda Spam Firewall features anti-virus technology specifically designed for rapid response to viruses that propagate and mutate quickly over botnets and through other bulk email delivery techniques.
When Barracuda Networks launched the Barracuda Spam Firewall in October 2003, most organizations already had anti-virus software, usually from the vendors of their desktop anti-virus software. These organizations were looking for an immediate solution to manage the deluge of spam coming into their mail servers, and the name Barracuda Spam Firewall was chosen to describe a solution to that core problem.
Since then, the threat landscape has evolved to the point where a desktop anti-virus software package retrofitted for mail server usage is no longer suited to provide maximum protection. Today’s botnets and zombies rapidly propagate and mutate not only commercial spam traffic but also virus and other malware traffic.
Over the past five years, Barracuda Networks has been developing and enhancing a purpose-built anti-virus engine specifically designed for email-borne threats, featuring:
- rapid response to new threats and variants
- prioritization of the threats that propagate most aggressively
- low false positives
- complete coverage by integrating signatures from ClamAV, the world’s largest free and open source software (FOSS) repository of virus definitions
Will there be any changes to pricing or part numbers?
No. While current firmware releases will be branded with the name Barracuda Spam Firewall, this change should be viewed as evolutionary, not revolutionary. The underlying technology enhancements, including Barracuda Real-Time Protection and Predictive Sender Profiling, have been introduced and continually evolving in the product for years.
Are there any changes to the product with this new name?
No. Pricing will not change with this announcement. Existing part numbers (e.g., BSF100) will still be used. A new price list will be distributed to existing resellers with new description fields, but part numbers and pricing will not change with this announcement.
How does the Barracuda Spam Firewall 300 protect against email threats?
The Barracuda Spam Firewall 300, an integrated hardware and software solution, uses a multilayered approach to provide the most comprehensive email protection available against spam, viruses, spoofing, phishing and spyware attacks. An added benefit of the Barracuda Spam Firewall 300 is the optimized processing of each email to maximize performance and capability to filter millions of messages per day.
Behind the industry-leading initiatives of Predictive Sender Profiling and Barracuda Real-Time Protection are 12 explicit defense layers including: Denial of Service and Security Protection, Rate Controls, IP Reputation Analysis, Sender Authentication, Recipient Verification, Virus Protection, Policy (user-specified rules), Fingerprint Analysis, Intent Analysis, Image Analysis, Bayesian Analysis, and a Spam Rules Scoring engine.
How is email filtered?
Deployed at the network perimeter, all incoming email must pass through all 12 defense layers of the Barracuda Spam Firewall before any of it can reach the intended recipients. The defense layers are grouped into two main classes: connection management, which involves dropping incoming mail connections before receiving messages, and mail scanning, which analyzes messages upon receipt. During the filtering process, emails are checked for new and familiar spammer attacks, viruses, and customized administrator policy violations. Based on administrator and user preferences, spam can be tagged, quarantined or blocked.
Why tag email? What happens to tagged emails?
Tagging email benefits organizations by easily identifying messages that meet set criteria. Tagged emails are delivered to the recipient with a customizable label, such as [BULK], that is added to the subject of the message.
Why quarantine email? What happens to quarantined email?
Quarantining emails is a safeguard that allows for examination of questionable messages prior to accepting or rejecting; typically, quarantined email does turn out to be spam. An administrator can choose two types of email quarantine: global or per user quarantine.
When configured for global quarantine, the Barracuda Spam Firewall 300 routes all quarantined email to a mailbox specified by the administrator. When configured for per user quarantine, the Barracuda Spam Firewall stores the email locally and notifies users periodically of their quarantined email. Users can choose to delete quarantined email, forward it to their own mailboxes or whitelist the sender address to prevent future email from being quarantined. Per user quarantine is available with the Barracuda Spam Firewall 300, 400, 600, 800 and 900 models.
What are some of the underlying technologies used in the Barracuda Spam Firewall ?
The Barracuda Spam Firewall uses a combination of proprietary and open source software. The Barracuda Spam Firewall 300 operating system is based on a hardened, stable Linux kernel that has undergone strict scrutiny by top security researchers. The robust MTA is capable of handling a high number of SMTP connections and mail delivery volumes. Starting with firmware release 3.5, the Barracuda Spam Firewall MTA has a built-in journaling function that can be used in conjunction with the Barracuda Message Archiver.
If I am using Microsoft Exchange, how will the Barracuda Spam Firewall 300 protect against “dictionary” attacks?
The Microsoft Exchange Accelerator, available on Barracuda Spam Firewall 300 and higher, uses the Lightweight Dictionary Access Protocol (LDAP) built into Exchange to verify recipients before delivering messages to the Microsoft Exchange Server.
What new technologies has the Barracuda Spam Firewall added to combat the latest spam campaigns?
In 2007 alone, Barracuda Networks has announced several initiatives against spam:
- Multi-Pass Optical Character Recognition Engine: Image spam generally embeds text within images with the intent of hiding content and bypassing the text rules processing layers of spam filters. With Barracuda Networks’ industry-leading multi-pass OCR engine, Barracuda Spam Firewall 300 render the spammers’ tricks to hide text behind color or blurred images ineffective.
- Predictive Sender Profiling: Barracuda Networks’ industry-leading Predictive Sender Profiling probes deeper into sent email and digs into the campaign itself to identify anomalous sender activity, allowing Barracuda Networks to effectively block spam typically unstoppable by traditional reputation analysis.
- Barracuda Real-Time Protection: Barracuda Real-Time Protection uses an advanced set of technologies to immediately block the latest virus, spyware and other malware attacks as they emerge.

The Barracuda Energize Updates subscription provides the latest spam and virus definition updates that block new campaigns before they become an outbreak. Barracuda Central engineers constantly update spam and virus definitions and are able to remotely tune six of the 12 defense layers, thereby minimizing administration time. Energize Updates also gives you access to technical support, new firmware releases and the opportunity to participate in the Barracuda Early Release Firmware program.
Does the Barracuda Spam Firewall offer per user policies?
Per user policies are available in Barracuda Spam Firewall and higher. Per user policies empower users with the ability to set their own individual scoring policies, Bayesian database, allow lists and block lists.
Can the Barracuda Spam Firewall filter outbound messages?
Yes. The Barracuda Spam Firewall filters outbound messages for viruses and basic spam scanning policies. For advanced outbound scanning, Barracuda Networks offers the Barracuda Spam Firewall-Outbound which includes different workflows for quarantining outbound email traffic for review by policy auditors.
How do I block or minimize the amount of invalid bounce messages?
Invalid bounce messages are non-delivery reports to forged email addresses. To block invalid bounce messages, enable the Invalid Bounce Suppression feature and relay all your outgoing email through the Barracuda Spam Firewall or the Barracuda Spam Firewall-Outbound appliance.
Does the Barracuda Spam Firewall enable administrators to block email from other countries?
Yes. The Barracuda Spam Firewall offers different ways to block spam from other countries:
- Based on a Reverse DNS lookup, administrators block messages whose top level domain resolves to a country’s hostname.
- Based on the declared character set of an email, administrators block messages that contain a specific language set.
- While it is not recommended by Barracuda Networks, administrators create custom policies to filter other patterns in the subject, header or body to block unwanted email from other countries.
How do I know which Barracuda Spam Firewall 300 model is best suited to my needs?
A local Barracuda Networks sales representative can evaluate your environment based on the number of active users, email traffic and desired features. As your organization expands, the Barracuda Spam Firewall can be clustered to accommodate your additional growth.
