The Secure Email Gateway (SEG) proxy server is a separate server installed in-line with your existing email server to proxy all email traffic going to mobile devices. Based on the settings you define in the UEM console, the SEG Proxy server allows or block decisions for every mobile device it manages.

The SEG Proxy server filters all communication requests to the corporate email server and relays traffic only from approved devices. This relay protects the corporate email server by not allowing any devices to communicate with it.

Install the SEG server in your network so that it is in-line with the email traffic of the corporation. You can also install it in a Demilitarized Zone (DMZ) or behind a reverse proxy. You must host the SEG server in your data center, regardless of whether your Workspace ONE MDM server is in the cloud or on premises.
