Workspace ONE UEM offers two types of deployment models to protect and manage your email infrastructure, the proxy model and the direct model.

You can use either of the following email deployment models along with the email policies that you define in the UEM console, to effectively manage your mobile devices.
  • In the proxy deployment model, a separate server called the Secure Email Gateway (SEG) proxy server is placed between the Workspace ONE server and the corporate email server. This proxy server filters all the requests from the devices to the email server and relays the traffic only from the approved devices. This way the corporate email server is protected as it does not directly communicate with the mobile devices.
  • In the direct deployment model, there is no proxy server involved and Workspace ONE UEM communicates directly with the email servers. The absence of proxy server simplifies the installation and configuration steps in this model.
Note: The proxy deployment model has two variants, the Classic and the SEG v2 platforms. The Classic SEG platform is no longer supported as the SEG V2 platform assures improved performance over the Classic platform. The SEG V2 platform can be installed on an existing SEG server with minimal downtime and during an upgrade, no profile changes or end-user interaction is required.
