Comprehensive Protection from Email-Based Threats

The Barracuda Email Security Gateway is an email security gateway that manages and filters all inbound and outbound email traffic to protect organizations from email-borne threats and data leaks. As a complete email management solution, the Barracuda Email Security Gateway lets organizations encrypt messages and leverage the cloud to spool email if mail servers become unavailable.

The Barracuda Email Security Gateway is offered without per-user or per-feature fees, and is also available as a virtual appliance or in a public cloud environment (Amazon Web Services (AWS), Microsoft Azure, or VMware vCloud Air).

Protect Against Email-Borne Threats

With the Barracuda Email Security Gateway, protecting against inbound malware, spam, phishing, and Denial of Service attacks ensures that business productivity isn't impacted by attacks through the email system. Powerful and customizable policies enable further enforcement of detailed requirements that govern inbound email messages.

Stop Threats before They Hit the Network

Offload CPU-intensive tasks like antivirus and DDoS filtering to the cloud reduces the processing load on the appliance and to ensure that threats never reach the network perimeter. The Barracuda Email Security Gateway is integrated with a cloud-based service that pre-filters email before delivery to the onsite Barracuda Email Security Gateway, which performs further inbound security checks and outbound filtering.
