Maximize Your Security, Minimize Your Risk
DRIVECRYPT protects your data with very fast and a true "on the fly" encryption process. Other products that claim to be "on the fly" decrypt an entire file and load it into memory, creating significant security risks. DriveCrypt is smarter and more secure because it decrypts only the specific portion of a file that is in use. Unprotected data never resides on a DriveCrypt encrypted hard drive.

Disk Partition and file volume encryption
(Partition encryption with DriveCrypt standard edition only)
DRIVECRYPT allows both, the encryption of an entire Hard Disk partition, as well as the creation of a virtual container file that will store all the encrypted information.

Invisible Containers
(DriveCrypt standard edition only)
The DriveCrypt Standard edition has the ability to create an INVISIBLE disk INSIDE a container or partition. This way you define two passwords for a container. The invisible disks password gives you access to your working disk, which is hidden in the unused area of your "outer" disk, while another password gives you access to the pre-setup DriveCrypt volume in which you only store data that you would want others to believe is the only data in the container or partition. This is very useful in cases where an aggressor may force you to reveal the DriveCrypt disk's password: By revealing the password of the first or "outer" disk, the aggressor will ONLY see the "prepared data": IE data you put in there, before creating the hidden disk, while he will not be able to see or get evidence that there is another invisible container that securely stores confidential data on the disk.
