The Barracuda Email Security Gateway, 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 Email Security Gateway 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.
Deployed at the network perimeter, all incoming email must pass through all 12 defense layers of the Barracuda Email Security Gateway 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.
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.
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 Email Security Gateway routes all quarantined email to a mailbox specified by the administrator. When configured for per user quarantine, the Barracuda Email Security Gateway 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 Email Security Gateway 300, 400, 600, 800 and 900 models.
The Barracuda Email Security Gateway uses a combination of proprietary and open source software. The Barracuda Email Security Gateway 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 Email Security Gateway MTA has a built-in journaling function that can be used in conjunction with the Barracuda Message Archiver.
The Microsoft Exchange Accelerator, available on Barracuda Email Security Gateway 300 and higher, uses the Lightweight Directory Access Protocol (LDAP) built into Exchange to verify recipients before delivering messages to the Microsoft Exchange Server.
Barracuda Networks has announced several initiatives against spam:
The Barracuda Email Security Gateway provides comprehensive protection against virus threats through three powerful layers. The first layer consists of a well-respected open source virus scanning engine. The second layer is a proprietary virus engine maintained by Barracuda Central, an advanced 24/7 security operations center that works to continuously monitor and block the latest Internet threats. The third layer is Barracuda Real-Time Protection, a set of advanced technologies that enable Barracuda Email Security Gateways to immediately block the latest virus, spyware and other malware attacks as they emerge without having to wait for a signature to be downloaded onto the Barracuda Email Security Gateway.
Barracuda Central engineers diligently work 24x7 monitoring spam and virus threats around the world. Since response times are crucial with real-time threats, when one is detected the Barracuda Email Security Gateway uses Barracuda Real-Time Protection to mitigate these threats as they emerge without waiting for new updates.
The Barracuda Email Security Gateway is designed as an easy-to-install appliance requiring minimal administrative overhead. Without any tuning, the Barracuda Email Security Gateway offers a 95 percent spam accuracy rate with a 0.01 percent false positive rate. Taking into account the six defense layers automatically tuned by Energize Updates, the Barracuda Email Security Gateway is easily kept up-to-date for ongoing spam accuracy.
With no tuning, the Barracuda Email Security Gateway is set to minimize false positives, typically at 0.01 percent or less – one of the lowest false positive ratings in the industry. As with any solution that allows for user customization, each customer’s false positive return will vary depending on how the administrator tunes the unit (i.e. a stricter spam score setting may result in more false positives).
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.
Most per user policy settings are available in Barracuda Email Security Gateway 300 and higher. Per user policies empower users with the ability to set their own individual scoring policies (available on models 600 or higher), Bayesian database, allow lists and block lists.
Yes. The Barracuda Email Security Gateway filters outbound messages for viruses and basic spam scanning policies. For advanced outbound scanning, Barracuda Networks offers the Barracuda Email Security Gateway-Outbound which includes different workflows for quarantining outbound email traffic for review by policy auditors.

Delivered as a cloud service, Barracuda Sentinel combines a powerful artificial intelligence engine, domain fraud visibility using DMARC, and anti-fraud training into a comprehensive solution that protects people, businesses, and brands from spear phishing, impersonation attempts, business email compromise (BEC), and cyber fraud.
