No Monitor or Keyboard Required

Citadel K-GL SSDs are specialized for headless applications. The system waits for an authorized USB security key to be inserted before unlocking and booting up. This allows you to protect against unauthorized access to data on UAVs, tactical edge devices, and appliances.

Data at Rest Security... Simplified

Citadel FIPS-certified self-encrypting drives (SEDs) are the only SSDs to integrate multifactor authentication, pre-boot authentication (PBA), and hardware encryption into a complete, low cost solution.

Pre-Boot Authentication Keeps Intruders Away

Powered by CipherDrive®, our built-in PBA unlocks access to the encrypted operating system or virtual machine on the Citadel K-GL SSD as well as the data stored there. This secured data is encrypted by NSA-approved Advanced Encryption Standard (AES) 256-bit encryption at the hardware level. Once booted, Citadel allows no-overhead, hardware-speed access to encrypted data at the full performance of the system. 

Commercial Solutions for Classified

Citadel K Series' PBA (EE) is CSfC-listed, which allows DoD, Federal agency, and critical infrastructure to protect mission critical and classified data using commercial solutions.

NIAP-Listed, TAA Compliant, and Common Criteria Certified

Citadel K Series SSDs are NIAP-listed, TAA compliant, have been tested and validated by the US Government to meet its security requirements for their cryptographic module, and have been listed by NIST as FIPS 140-2 L2 certified storage devices with NIST Certificate #3926.

Wide OS and Hypervisor Compatibility
