AlertSec Endpoint Encrypt includes pre-boot authentication, which ensures that only authorized users are allowed to access the computer. A common misconception is that a BIOS password conveys the same level of security as the pre-boot protection included in AlertSec Endpoint Encrypt. This is not the case.
BIOS level protection schemes only protect the actual BIOS settings. Whilst it is important for controlling access to the computer, this does not fully protect the data stored on the disk. For example, it would be possible to use a boot disk and bypass the boot protection; removing the drive and placing it in another computer would also make the files accessible.
To secure stored data, it must be encrypted. Once encrypted with full disk encryption, the files will be inaccessible to any unauthorized person and immune to the widely available password cracking tools.
