USB pass-through dongle with AES 256-bit hardware encryption

The Enigma is a USB ciphering dongle that transparently encrypts data stored inside any USB drive including Blu-Ray DVD, DVD R/W, CD-R, thumb drive, hard disk or any flash card inserted into a USB card reader. Installation is easy. Simply insert the USB drive to the Enigma dongle then plug into a standard USB port. The drive appears in the computer in a few seconds and is ready for use just like any ordinary USB drive. All data written to the USB drive is automatically encrypted via the Enigma dongle with NIST/CSE certified AES ECB/CBC 256-bit strength. There is no software or driver to install and no password to remember. All your software works the same as before except that stored data are wire speed encrypted. The encrypted USB drive can be used on any system so long as you have possessed the Enigma dongle.

How does it work ?

The Enigma sits between a USB host and the USB device, encrypting data before it is written to the storage and decrypting while it is read. The cryptographic operation is totally transparent to users thus produces no performance loss while all data-at-rest are hardware AES 256-bit encrypted. The operation is easy to use and requires no additional IT training.

Remark #1
Some composite device such as Western Digital My Book Studio Edition 4TB has equipped with more than one interface. The WD 4TB drive comes with an extra HID/SES interface in addition to the USB MSC interface. The Enigma supports current WD 4TB drive under Windows 7 32/64-bit platform. Having said, we have not exhausted testing over other brands thus can not guarantee full compatibility with other 4TB drives. If incompatibility issue occurs, please inform us and send us your configuration data as we will be pleased to try to resolve the technical difficulties for you.
