Explanation

Full-disk (or device) encryption ensures that, even if a lost mobile device is physically accessed by an unauthorized party, its stored data remains inaccessible without the correct decryption credentials. This protection is automatic and continuous, safeguarding data at rest regardless of whether the user realizes the device is missing or not. Remote wipe can remove data if triggered, but it requires the device to be online and the user (or admin) to initiate the wipe--whereas encryption is always in effect.
