Custom Panorama Admin:
Custom Panorama Admin roles allow you to customize the elements of Panorama that an administrator can access. You can hide tabs in the web interface, you can set specific items in Panorama to read-only, or you can limit an administrator’s access to Panorama plugins. Custom Panorama Admin roles require planning and configuration, but they provide extensive flexibility because you can control what administrators can access through the web interface or the CLI.
Device Group and Template Admin:
Device Group and Template Admin roles also require configuration because there are no built-in examples. These Admin Roles allow you to define which Panorama templates or Panorama device groups an administrator can access and configure. You can hide tabs in the web interface or set specific items to read only to control what administrators can configure.
