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 Cigent®, our built-in PBA unlocks access to the encrypted operating system or virtual machine on the Citadel 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.

Adversaries cannot steal what they cannot see

Unreadable storage partition protected by non-recoverable key.

Worry-Free Deployment

Cigent software is tested and validated for use with DIGISTOR SSDs.

Multi-Factor Authentication (MFA)

Requires more than one authentication for access. Multiple authentication methods include password, CAC/PIV smartcard, and PIV-supported Yubikey.

Additional Authentication for File Access

Zero-day ransomware, malware, and software service bypass prevention.

NIAP-Listed, TAA Compliant, and Common Criteria Certified

Citadel C Series Advanced SSDs are NIAP-listed, TAA compliant, and have been listed by NIST as FIPS 140-2 L2 certified storage devices with NIST Certificate #4294.

Verified Device Erasure

Ensures every block has truly been wiped.

Immutable Insider Detection

Secure data access logs capture all insider threat activity.

Automated Threat Response

Makes data invisible if Cigent Data Defense is disabled.

Address critical requirements for data governance and privacy programs

Citadel C Series SSDs meet CMMC, HIPAA, GDPR, GLBA, PCI-DSS, and CCPA requirements.
