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-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. A Complete CSfC Layer 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.
