Whole Disk Encryption

Encrypting your computer through Whole Disk Encryption is one of the most effective ways to protect information stored on your hard drive. If your computer stores or processes high risk data, encrypting your hard drive is a necessary step to ensure the security of any data in case of loss or theft of your device. High risk data should only be stored on approved ITS servers under UI policies and standards; however, to protect any incidental data that may accidentally reside on your local system, Whole Disk Encryption is an essential best practice.

Sophos SafeGuard manages the built-in encryption technologies for both Windows and Mac desktop and laptop computers, and once installed will seamlessly encrypt all data stored on your hard drive(s). This information is safe while the computer is shut down and requires a password before the information can be accessed again. If your device is ever lost or stolen, ITS can verify that the device was encrypted and that your information cannot be accessed by any third party.
