The Guardian Edge Endpoint solution has been awarded the status of EAL4+.

The GuardianEdge Platform provides transparent encryption services for hard disks and removable storage devices on computers running Windows XP, Windows 2000, and Windows Vista. It employs full disk encryption, pre-boot authentication, and on-the-fly disk decryption/encryption at the device driver level to provide complete protection of data on Windows-based notebook and desktop systems. It also protects information on removable storage devices such as USB flash drives.

The GuardianEdge Platform protects data at rest on the hard disk and on removable devices from unauthorized access. The GuardianEdge Platform uses its own FIPS 140-2 (Level 1, Validated crypto module, Certificate No. 515) validated cryptographic library to perform the cryptographic operations necessary to protect data, support authentication, and self-protect against tampering or bypass. The product uses Advanced Encryption Standard (AES) in Cipher Block Chaining (CBC) mode with 256-bit keys to perform bulk encryption on administrator-specified partitions of hard disks and removable storage devices on a Client Computer.
