3. The computer-implemented method of claim 2, wherein the server communicatively coupled to the user device comprises a proxy server or a file server.

4. The computer-implemented method of claim 1, wherein the at least one compliance rule requires that the user device be associated with a certain enterprise.

5. The computer-implemented method of claim 4, wherein the user device is associated with the certain enterprise if user account data associated with the user device indicates that a user of the user device is employed by the certain enterprise.

6. The computer-implemented method of claim 4, wherein the user device is associated with the certain enterprise if user account data indicates that the user device is owned by the certain enterprise or managed by the certain enterprise through an enterprise mobility management service.

7. The computer-implemented method of claim 4, further comprising determining, by the computing device, that the at least one watermark template was applied by a foreign device associated with a foreign enterprise, the foreign enterprise being different than the certain enterprise.

8. The computer-implemented method of claim 1, wherein the at least one compliance rule requires that the watermark template specify an association between the at least one resource and an enterprise.

9. The computer-implemented method of claim 1, wherein the at least one compliance rule requires that the watermark template specify a sensitivity level associated with the at least one resource.

10. The computer-implemented method of claim 1, wherein determining, by the computing device, that the watermark template has been applied to the at least one resource comprises:

identifying, by the computing device, a file associated with the at least one resource containing metadata describing the at least one resource; and

analyzing, by the computing device, the file to determine that the watermark template has been applied to the at least one resource using the metadata, wherein the metadata comprises the plurality of data elements.

11. The computer-implemented method of claim 1, wherein the scan of the memory of the user device or the remote storage is caused in response to an onboarding process where the user device is enrolled with an enterprise mobility management service.

12. A system, comprising:

at least one computing device comprising at least one hardware processor; and

program instructions executable in the at least one computing device that, when executed, cause the at least one computing device to;

scan memory of a user device or a remote storage device to identify at least one resource that has been made accessible to the user device;

determine that a watermark template has been applied to the at least one resource, the watermark template comprising a plurality of data elements, at least a portion of the plurality of data elements added when the at least one resource was generated or modified, a first one of the plurality of data elements comprising a function performed on the user device that generated or modified the at least one resource and a second one of the plurality of data elements comprising a sensitivity level associated with the at least one resource;

in response to a determination that the watermark template has been applied to the at least one resource accessible to the user device;

identify at least one compliance rule according to the watermark template applied to the at least one resource, wherein the at least one compliance rule requires that the function performed on the user device comply with the sensitivity level associated with the at least one resource;

determine that the user device does not comply with the at least one compliance rule in response to the function identified from the first one of the plurality of data elements not complying with the sensitivity level; and

in response to the user device not complying with the at least one compliance rule, perform at least one remedial action in association with the at least one resource specified by the at least one compliance rule, the at least one remedial action comprising at least one of;

a denial of access to the at least one resource by the user device,

a removal of the at least one resource from the memory of the user device, or

a removal of the at least one resource from memory of the remote storage device.

13. The system of claim 12, wherein the removal of the at least one resource from the memory of the user device or the remote storage device comprises deleting the at least one resource.

14. The system of claim 12, wherein the at least one remedial action further comprises quarantining the at least one resource.

15. The system of claim 12, wherein the removal of the at least one resource from the memory of the user device or the remote storage device comprises deleting only a portion of resource data residing in the memory of the user device or the remote storage device.
