Protect Your Data; Safeguard Your Privacy 

Product Overview

The X-Wall SE ASIC ensures privacy and confidentiality of data and credentials stored on PC hard drives without degrading system performance. A cryptographic system-controller ASIC operating at the physical layer, the X-Wall microchip performs bit-by-bit “real-time” encryption of the entire hard disk (including the boot sector and operating system) at 1.1 Giga bit per second using Federal Government certified DES/TDES algorithms. In contrast to software solutions, no password is ever stored on the hard drive or held in machine memory. X-Wall’s unique design also completely eliminates any dependency on operating systems or device drivers while functioning automatically and transparently, thereby eliminating user intervention.

Key Features

- Automatic transparent encryption guarantees user acceptance and enforces compliance with security policies
- Real-time encryption at 1.1 Gbit/sec maintains full system performance
- Government-certified DES and TDES algorithms assure high level security
- Encryption key lengths from 40-bit to 192-bit
- Compatible with any IDE hard drive, regardless of operating system and requiring no additional device drivers
- Small form factor with low power consumption


The X-Wall® SE chip resides between the IDE host controller and the IDE hard drive. Incorporating both a host and target interface for IDE Ultra DMA drives, X-Wall® SE acts as a host controller to the hard drive and as a hard drive to the controller. X-Wall® intercepts and translates IDE commands and encrypts all data in real-time. All data written to the hard drive, including the boot sector, operating system, temp and swap files, is automatically and transparently encrypted. Attempts to circumvent security by booting from a floppy disk or by removing the hard drive to be read on a different machine would prove futile since the entire content of the hard drive is encrypted.


The X-Wall Secure Key stores and protects the "Secret key" used by the X-Wall® microchip to encrypt data. The correct X-Wall Secure Key must be inserted into the special key socket (present on X-Wall® finished products) at system boot up to authenticate the user and authorize the operating system to load before granting access to data stored on the hard drive.

Don't like the Secure Key?

We understand you might have preference over using other authentication devices for authentication. Attempt to replace the external key token is possible with some level of system engineering efforts. Please note, the current X-Wall SE/LX version has a hardwired interface which communicates directly to the external key token upon boot up. One can easily emulate the interface (protocol) such that BIOS PIN/Password and/or any other third party authentication device makers such as Smartcard or Fingerprint can function with X-Wall SE/LX to replace the external key token. Please contact us for an in depth engineering architecture.
