GiliSoft Full Disk Encryption is especially useful for laptops and other small computing devices that can be physically lost or stolen. It offers encryption of all disk partitions, including the system partition. Through password protecting a disk, disk partition or operating system launch, the program disables any unauthorized reading/writing activity on your disk or PC, restricts access and launch of specific disks and files. It provides automatic security for all information on endpoint hard drives, including user data, operating system files and temporary and erased files. For maximum data protection, multi-factor pre-boot authentication ensures user identity, while encryption prevents data loss from theft. Tips: This tool does NOT encrypt boot partition on drive with GPT partition table. If have GPT drive and want to encrypt boot partiton with Full Disk Encrytion, please convert GPT drive to MBR first and disable bios UEFI, disable Memory Fast Boot.
