The Barracuda Email Security Gateway provides a comprehensive set of encryption features to ensure the security and privacy of outbound emails. One of its key features is its integration with a cloud-based email encryption service, which allows for seamless encryption of outbound emails. This integration ensures that any email that matches a specific policy or is marked for encryption via the Barracuda Outlook Add-in is securely sent via TLS to the Barracuda Message Center.
The Barracuda Message Center, which acts as a central hub for encrypted emails, utilizes AES with 256-bit keys to encrypt the email content. This level of encryption ensures that the email data remains secure and protected from unauthorized access. Additionally, the Barracuda Email Security Gateway’s Message Transport Agent supports SMTP over TLS, enabling the encryption of email traffic between different sites over the Internet. This feature can be utilized not only between Barracuda Email Security Gateways but also with other email servers that support SMTP over TLS.
In addition to encryption, the Barracuda Email Security Gateway offers robust outbound filtering capabilities. This feature prevents organizations from being blacklisted as a source of spam and ensures that sensitive email data does not leave the organization’s network. One common issue faced by organizations is the unintentional contribution to botnet spam through internal systems. The Barracuda Email Security Gateway’s outbound filtering addresses this concern by utilizing a subset of its defense layers to detect and stop outbound spam and viruses. Furthermore, administrators have the ability to enforce content policies for data loss prevention (DLP) and meet other content standards in outgoing email. This is achieved through the use of predefined filters and custom policies, which can be configured to detect sensitive data and either block or encrypt the email accordingly.
Overall, the Barracuda Email Security Gateway offers a comprehensive solution for email encryption and outbound filtering. Its integration with a cloud-based email encryption service, support for AES with 256-bit keys, and SMTP over TLS capabilities ensure the secure transmission of outbound emails. Additionally, its outbound filtering features prevent organizations from being blacklisted and enable administrators to enforce content policies for data loss prevention and compliance purposes.
