M86 MailMarshal Secure Email Gateway

Comprehensive Email Gateway Security

M86 MailMarshal Secure Email Gateway (M86 MailMarshal SEG) provides total email content security through unified threat management, anti-spam, content security, policy enforcement and data leakage prevention. Powered by the M86 Defense-in-Depth Anti-spam Engine, it acts as a secure email gateway to filter all incoming and outgoing email at the perimeter. Highly scalable, flexible and easy to manage, M86 MailMarshal SEG can be deployed as a standalone solution or as a distributed array designed to support the largest networks, including centralized administration.

Using deep content inspection capabilities, M86 MailMarshal SEG scans all content—even within email attachments—giving organizations the control they need to proactively and productively exchange information without worrying about harmful data leaks.
