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 Series 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. 

Multi-Drive Support

Unlock one SSD to authorize access to all SSDs. Perfect for tactical servers and other systems with multiple Citadel K Series SSDs installed.

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.
