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.

Powered by CipherDrive® our built-in PBA unlocks access to the encrypted operating system or virtual machine on the Citadel K-SD 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. 

All DIGISTOR FIPS SEDs—including Citadel K Series SEDs—are listed on the NSA CSfC Component List for hardware full drive encryption which allows DoD Federal agencies and critical infrastructure to protect mission critical and classified data using commercial solutions. Together with the built-in PBA  which is also CSfC listed for hardware full drive encryption a Citadel K Series SED constitutes a complete CSfC layer.

All Citadel K-Series SEDs are NIAP-compliant  (VID #11297) TAA compliant and have been listed by NIST as FIPS 140-2 L2 certified storage devices with NIST Certificate #3926 ensuring they meet most stringent cybersecurity standards.

Citadel K-SD SEDs are used in Windows and Linux operating systems as well as with SecureView and Forcepoint.

Computer systems that are supported by Citadel K Series SEDs are contained in this hardware compatibility list (HCL).
