Systems and methods of device management are disclosed. Aspects relate to systems and methods that may be implemented to control usage of one or more devices. In one embodiment, a device management system includes a memory, an interface, at least one processor coupled to the memory and the interface, and a control component executable by the at least one processor and configured to determine, at a predetermined time, whether a connection exists between a managed device and the device management system via the interface, generate, in response to determining that the connection did not exist at the predetermined time, a notification indicating that the connection does not exist, and transmit, in response to determining that the connection did not exist at the predetermined time, a request to the managed device to restrict at least one function of the managed device.
