Barracuda Spam Firewall Technology
12 Defense Layers: Barracuda Networks multilayered approach to email security provides the most comprehensive protection available, and optimizes the processing of each email to maximize performance and process 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.

Barracuda Reputation and Intent Analysis: While the standalone value of reputation data is diminishing, it remains an important baseline for sender profiling. For reputation analysis, the Barracuda Spam Firewall leverages data on both the network addresses used to send email as well as the domain names embedded in the Web links of emails gathered by Barracuda Central, an advanced technology operations center where engineers continually monitor the Internet for trends in spam and virus attacks. Combining both the IP and reputation data enables Barracuda Networks to implement countermeasures to mitigate all spam and virus threats. Learn More…
Predictive Sender Profiling: Relying solely on reputation analysis is no longer enough to efficiently prevent today’s sophisticated spam attacks. The industry-leading Predictive Sender Profiling probes deeper into sent email to identify bad sender behavior and block identity obfuscation techniques, despite a sender’s lack of prior spamming history. As the next generation of anti-spam technology, Predictive Sender Profiling reinforces the superior 95 percent spam accuracy rate of the Barracuda Spam Firewall. Learn More…
Barracuda Real-Time Protection: Barracuda Real-Time Protection is a set of advanced technologies that enables Barracuda Spam Firewalls to immediately block the latest virus, spyware, and other malware attacks as they emerge. These capabilities provide industry-leading response times to email-borne threats by adding a third layer of antivirus protection to the Barracuda Spam Firewall. Learn More…
Triple Layer Antivirus Protection: The Barracuda Spam Firewall scans all email messages and all incoming files for viruses using three powerful layers of virus scanning technology and automatically decompresses archives for complete virus protection. Barracuda Networks triple-layer virus blocking includes powerful open source and proprietary virus definitions and Barracuda Real-Time Protection. Virus scanning takes precedence over all other mail scanning techniques, and it is applied even when mail passes through the connection management layers. As such, even email coming from “whitelisted” IP addresses or senders, or addressed to whitelisted recipients, are still scanned for viruses and blocked if a virus is detected. Learn More…
Image Spam Protection: Image spam, which generally embeds text inside images with the intent of hiding content from traditional spam filters, represents approximately one-third of all traffic on the Internet. The Barracuda Spam Firewall was the first major email security product to include image analysis techniques to effectively protect against new image spam variants. Learn More…
PDF Spam Protection: In late June 2007, spammers engaged in new spam campaigns in which they embedded messages within PDF documents. By using PDF files that require the use of document viewing applications, such as Adobe Reader, spammers attempted to bypass text and image scanning engines in email security products. Because these PDF attacks utilized existing botnets to generate similar traffic patterns on the Internet as more traditional spam attacks, both Barracuda Reputation and Fingerprint Analysis techniques enabled the Barracuda Spam Firewall to block a significant portion of PDF spam very early in the message scanning process. Learn More…
Mail Transport and Policy: The Barracuda Spam Firewall features a robust Message Transport Agent (MTA) capable of handling high SMTP connection and mail delivery volumes. For inbound protection, the MTA includes a number of built-in protections, including rate controls, IP reputation analysis, sender authentication, and recipient verification, which allow rejection of SMTP connections before actually receiving any messages itself. Learn More…
Clustering: The Barracuda Spam Firewall supports clustering of multiple nodes for both redundancy and to increase total system capacity. For centralized management, Barracuda Spam Firewalls share configuration and policy across the cluster, and administrators can change policy or access any message received across the cluster from any individual node. For redundancy of quarantine mail storage, all quarantined messages are stored in at least two nodes in the cluster – ensuring that messages are always available in the event that one node becomes unavailable. Barracuda Spam Firewall clusters can span geographies to facilitate redundancy across sites. Learn More…
