Secure Email Gateway Definition

A simple email gateway definition is that email gateways are mail servers that protect an organization’s mail servers by serving as a filter. All incoming and outgoing emails pass through these secure servers, thus making them “Gateways” for a user’s email platform, this is the definition of secure email gateway. Email gateways do not host the inbox of the user.

Understanding How Email Gateway Works

An SEG (Secure Email Gateway) is a software or device applied to monitor emails that are received as well as sent. They allow scanned emails to pass on to the internal servers of an organization if these emails do not contain spam or malware, this is how email gateway works. SEGs quarantine emails that may be harmful. Emails are also encrypted to protect sensitive information.
