The Barracuda Spam & Virus Firewall provides a powerful, easy-to-use and affordable solution for complete protection of an organization’s email infrastructure. It eliminates spam and virus intrusions while safeguarding an organization’s reputation through content inspection based on policy for both inbound and outbound email.

The Barracuda Spam & Virus Firewall architecture optimizes the processing of each email to maximize performance and process millions of messages per day. Unlike software solutions, the Barracuda Spam & Virus Firewall reduces the load placed on the email server by offloading both spam and virus filtering.

All Barracuda Spam & Virus Firewall models include comprehensive outbound filtering techniques including attachment scanning, virus filtering, rate controls and encryption. These features help organizations to ensure that all outgoing email is legitimate and virus-free.

In addition, Barracuda Spam & Virus Firewall includes email encryption using a cloud-based portal and Data Loss Prevention features like attachment content scanning.

It Provides a Cloud Protection Layer

Barracuda Spam & Virus Firewall includes a Cloud Protection Layer to stop spam and viruses in the cloud. In this mode, inbound emails are first scanned by the cloud before delivery. The Cloud Protection Layer also features multiple delivery options. If the primary delivery destination is unavailable, then emails are delivered to a secondary destination. If both the primary and secondary destinations are unavailable, then undelivered email is stored for later delivery.

It's Easy-to-Use

With no software to install or modifications required to existing email systems, installation of the Barracuda Spam & Virus Firewall is quick and easy. Once installed, the system administrator uses the intuitive Web interface for monitoring and maintenance. With Barracuda Networks Energize Updates, the Barracuda Spam & Virus Firewall is continuously updated with the latest spam and virus definitions every hour keeping maintenance to the unit at a minimum and eliminating administrative overhead. Updates are provided by Barracuda Central, an advanced 24x7 security operations center that works to continuously monitor and block the latest Internet threats.
