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 C-SEL SED 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 Citadel C-SEL SEDs.

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.

TCG Opal 2.0

Protected with AES 256-bit encryption and random key generation at the hardware level, ensuring fast file access without any overhead.

TAA Compliant

Citadel C-SEL SEDs are TAA compliant so they can protect information on government systems.

Address critical requirements for data governance and privacy programs

Citadel C-SEL SEDs meet CMMC, HIPAA, GDPR, GLBA, PCI-DSS, and CCPA requirements.
