Citadel's simplified FIPS-certified self-encrypting drives (SED) are the only SSDs that integrate multi-factor authentication, pre-boot authentication (PBA), and hardware encryption into a complete, low-cost solution. Pre-Boot Authentication Keeps Intruders Out 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 protected data is encrypted by NSA-approved Advanced Encryption Standard (AES) 256-bit encryption at the hardware level. Once started, Citadel enables overhead-free, hardware-speed access to encrypted data at full system performance. A Complete CSfC Layer All DIGISTOR FIPS SEDs, including Citadel K-series SEDs are listed on the NSA CSfC Component List for hardware full disk encryption, enabling the Department of Defense, agencies Federal and critical infrastructure protect critical and classified data using commercial solutions. Together with the built-in PBA, which is also CSfC listed for hardware full disk encryption, a Citadel K Series SED constitutes a complete CSfC layer. NIAP compliant, TAA compliant and Common Criteria certified. 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 comply with the strictest cybersecurity standards. Support for Broad Operating Systems and Hypervisors Citadel K-SD SEDs are used on Windows and Linux operating systems, as well as SecureView and Forcepoint. Compatible with Major Computer Manufacturers Computer systems compatible with Citadel K-Series SEDs are listed on this Hardware Compatibility List (HCL).
