Chrome Enterprise Management (CEM) is a web based admin console you license from Google to remotely manage your Chrome device hardware. The perpetual license is valid for the life of the device but can be transferred to a like device in the event of a device issue. This license is a great choice for digital signage as it allows you to “set it and forget it” and not worry about renewing the licenses yearly. CEM allows a Chrome device to be set into Kiosk App Mode which keeps your digital signage locked to only play your Arreya channel and will automatically return to your Arreya channel if the device is turned off or loses connection. No worries about unwanted hijacking of your display to access other websites or having address bars on your digital signage. From your cloud-based Google admin console the Chrome Enterprise license allows you to configure policies and settings for Chrome devices, manage users, manage apps, configure networks, connect devices to your VPN and Wi-Fi networks, and manage other features of Chrome. Chrome Enterprise includes 24/7 Enterprise support from Google.
If you encounter a hardware issue and need to replace a device, you can transfer the license to another device of the same model (or equivalent manufacturer-provided replacement). You can not transfer a license to a device in another domain.
