Silver Award:

Barracuda Spam Firewall

Barracuda Spam Firewall snagged the silver medal, winning high marks from readers in several categories. The appliance scored high in its ability to block spam and malware, integration with existing applications, end -user transparency, and ease of installation and administration.

The device, which comes in seven models, provides integrated antispam, antivirus, anti-phishing, and antispyware protection. It uses several techniques to protect an email server, including IP reputation analysis, sender authentication, user-specified policies, Bayesian analysis, and rule-based scoring. End -user control features allow for fine tuning and enhanced accuracy.

A single Barracuda Spam Firewall handles up to 30,000 active mail users; multiple units can be clustered for high availability. All models include outbound filtering techniques such as attachment scanning, virus filtering and rate control to ensure outgoing email is legitimate.

A system administrator monitors and manages the applications via a Web interface, and Barracuda's security operations center continuously updates the firewall with spam and virus definitions.
