Supervision or supervised mode is a special mode that allows IT administrators and organizations to gain extensive remote controlling capability over Apple devices (iPhone, iPad and Mac). It allows some device restrictions like turning off iMessage or content erase. It also provides additional device configurations and features like web content filtering, preventing app deletion, silently installing and removing apps, disabling access to AirDrop, configuring a global proxy, enabling single-app mode, MDM lockdown, etc. For more information, read our help center page on supervised devices.
