DigiSAFE DeskCrypt – Your Data Stays Yours

DigiSAFE DeskCrypt is hardware-based encryption device that secures data in a SATA hard disk drive against hackers and information thieves. Uniquely designed as a bump-in-the-wire device used in desktops, DeskCrypt requires no mounting and simply plugs in between the SATA connector on the motherboard and the hard disk drive. It operates transparently and encrypts all data written onto the hard disk without any loss in disk performance.

DeskCrypt does not require any additional software drivers or applications to be installed and is operating
system independent. Once deployed, users would be assured that all the data on their hard disks is fully protected from unauthorized access in the event that the hard disk is lost or stolen.

Use Case

Pre-boot Authentication

DigiSAFE DeskCrypt authenticates the user every time the PC powers on or resumes from hibernation. The PC will only
boot into the Operating System on the attached hard disk drive upon successful user authentication. DeskCrypt offers two authentication modes:

1. Single-Factor authentication:

In this mode of authentication, the user is prompted for a Password at the pre-boot stage after power-on. DeskCrypt grants access to the user if the correct password is presented.

2. Two-Factor authentication:

In this mode, the user is prompted for DigiSAFE KeyCrypt® USB cryptographic token (something you have), as well as the password associated with the token (something you know). DeskCrypt grants access only if the correct token and password is presented.
