Stay One Step Ahead of Cyber Threats with Barracuda Email Security
Stay One Step Ahead of Cyber Threats with Barracuda's Email Security Gateway
The Barracuda Email Security Gateway offers a number of encryption features. It is fully integrated with a cloud-based email encryption service for outbound email. Email that matches policy or is marked for encryption via the Barracuda Outlook Add-in is sent securely via TLS to the Barracuda Message Center.
The Barracuda Message Center uses AES with 256-bit keys to encrypt email. To encrypt email traffic between sites over the Internet, the Barracuda Email Security Gateway Message Transport Agent supports SMTP over TLS. This can be used between Barracuda Email Security Gateways or other email servers that support SMTP over TLS.
Outbound filtering prevents organizations from being put on spam block lists and prevents sensitive email data from leaving the organization. Employees can inadvertently cause internal systems to become a source for botnet spam. By using a subset of its defense layers, the Barracuda Email Security Gateway’s outbound filtering stops outbound spam and viruses. It also lets administrators enforce content polices for data loss prevention (DLP) and meet other content standards in outgoing email. Predefined filters and custom policies can be used to detect sensitive data and block or encrypt email.
