Remotely restricting client devices

1. A method performed by at least one computing device to manage or oversee the operation of client devices, the method comprising:

obtaining, from a client device, a request to register the client device with the at least one computing device as a managed device;

in response to obtaining the request to register the client device, generating, in a user interface (UI) of the at least one computing device, an entry associated with the client device, wherein the generated entry identifies the client device or a user associated with the client device;

obtaining, via a selection of the generated entry in the UI, a request to place the client device in a restricted mode;

in response to obtaining the request to place the client device in the restricted mode, generating at least one restrict command to place the client device in the restricted mode, wherein the at least one restrict command identifies at least one permitted application, and the at least one restrict command includes an instruction to restrict an operating system (OS) of the client device to allow only the at least one permitted application to execute in the foreground and to receive inputs made into the client device; and

transmitting the at least one restrict command to the client device to cause the client device to be placed in the restricted mode, wherein in the restricted mode, the client device restricts the OS to allow only the at least one permitted application to execute in the foreground and to receive inputs made into the client device.

2. The method of claim 1 , wherein the at least one restrict command further includes an instruction to disable a file explorer or shell from executing on the client device or to disable a task manager from executing on the client device.

3. The method of claim 1 , further comprising:

after transmitting the at least one restrict command to the client device, obtaining, from the client device, a screen capture of a display of the client device; and

updating the UI to include a representation of the obtained screen capture.

4. The method of claim 1 , further comprising:

obtaining, via another selection of the generated entry, a request to remove the client device from the restricted mode;

in response to obtaining the request to remove the client device from the restricted mode, generating at least one remove command to remove the client device from the restricted mode, wherein the at least one remove command includes an instruction to stop restricting the OS of the client device to allow only the at least one permitted application to execute in the foreground and to receive inputs made into the client device; and

transmitting the at least one remove command to the client device to cause the client device to be removed from the restricted mode, wherein based on the removal from the restricted mode, the client device stops restricting the OS to allow only the at least one permitted application to execute in the foreground and to receive inputs made into the client device.

5. The method of claim 1 , wherein the at least one permitted application comprises a web browser application that the OS allows to execute while the client device is in the restricted mode.

6. The method of claim 5 , wherein the at least one restrict command further identifies a network whitelist comprising at least one network address that the web browser application is allowed to access while the client device is in the restricted mode.

7. The method of claim 1 , further comprising:

transmitting the UI to an administrative device separate from the client device, wherein the request to place the client device in the restricted mode is obtained from the administrative device based on a selection of the generated entry of the UI made at the administrative device.

8. The method of claim 1 , further comprising:

obtaining, from the client device, data that indicates a status of settings of the client device;

determining, based on the obtained data, that the client device is not compliant with one or more compliance rules; and

in response to determining that the client device is not compliant, transmitting a message to the client device that either causes the settings of the client device to change or erases data from the client device.

9. A non-transitory computer-readable medium comprising instructions that are executable by a remote computing device, wherein the instructions when executed cause the remote computing device to carry out a method to manage or oversee the operation of client devices, and wherein the method comprises:

obtaining, from a client device, a request to register the client device with the remote computing device as a managed device;

in response to obtaining the request to register the client device, generating, in a user interface (UI) of the remote computing device, an entry associated with the client device, wherein the generated entry identifies the client device or a user associated with the client device;

obtaining, via a selection of the generated entry in the UI, a request to place the client device in a restricted mode;

in response to obtaining the request to place the client device in the restricted mode, generating at least one restrict command to place the client device in the restricted mode, wherein the at least one restrict command identifies at least one permitted application, and the at least one restrict command includes an instruction to restrict an operating system (OS) of the client device to allow only the at least one permitted application to execute in the foreground and to receive inputs made into the client device; and

transmitting the at least one restrict command to the client device to cause the client device to be placed in the restricted mode, wherein in the restricted mode, the client device restricts the OS to allow only the at least one permitted application to execute in the foreground and to receive inputs made into the client device.

10. The non-transitory computer-readable medium of claim 9 , wherein the at least one restrict command further includes an instruction to disable a file explorer or shell from executing on the client device or to disable a task manager from executing on the client device.

11. The non-transitory computer-readable medium of claim 9 , wherein the method further comprises:

after transmitting the at least one restrict command to the client device, obtaining, from the client device, a screen capture of a display of the client device; and

updating the UI to include a representation of the obtained screen capture.

12. The non-transitory computer-readable medium of claim 9 , wherein the method further comprises:

obtaining, via another selection of the generated entry, a request to remove the client device from the restricted mode;

in response to obtaining the request to remove the client device from the restricted mode, generating at least one remove command to remove the client device from the restricted mode, wherein the at least one remove command includes an instruction to stop restricting the OS of the client device to allow only the at least one permitted application to execute in the foreground and to receive inputs made into the client device; and

transmitting the at least one remove command to the client device to cause the client device to be removed from the restricted mode, wherein based on the removal from the restricted mode, the client device stops restricting the OS to allow only the at least one permitted application to execute in the foreground and to receive inputs made into the client device.

13. The non-transitory computer-readable medium of claim 9 , wherein the at least one permitted application comprises a web browser application that the OS allows to execute while the client device is in the restricted mode, and wherein the at least one restrict command further identifies a network whitelist comprising at least one network address that the web browser application is allowed to access while the client device is in the restricted mode.
