Barracuda Networks, a provider of content security appliances, has enhanced its email virus and malware threat prevention techniques, enabling its newly renamed Barracuda Spam & Virus Firewall to identify viruses and other email-borne malware threats.

Through advanced technologies, such as Barracuda Real-Time Protection and Predictive Sender Profiling developed for spam and email-borne malware, Barracuda Spam & Virus Firewalls provide response times to email-borne threats, said Barracuda Networks.

Immediately upon virus or malware classification, Barracuda Spam & Virus Firewalls running Barracuda Real-Time Protection perform live queries for unknown fingerprints against the Barracuda Central virus and spam fingerprint databases, avoiding any need to wait for the next virus definition download for protection. Once categorized, new fingerprints are included in subsequent spam and virus definitions downloaded by Barracuda Spam & Virus Firewalls through Energize Updates, avoiding the need to perform real-time queries.

Stephen Pao, vice president of product management at Barracuda Networks, said: What differentiates Barracuda Networks from the competition is that our products are purpose-built to solve the unique needs of email and web security appliances. Unlike desktop anti-virus engines retrofitted for email server usage, the Barracuda Spam & Virus Firewall.
