What Is Data-at-Rest Encryption?

Data-at-rest encryption secures inactive data—such as files stored on a hard drive, database, or cloud storage—by converting it into an unreadable format unless accessed with the correct cryptographic key. This ensures that even if a system is breached or a device is stolen, the data remains protected and inaccessible to unauthorized parties.


Why It Matters

  • Prevents Data Breaches
    Encrypted data remains unusable to attackers even if storage systems are compromised.
  • Meets Compliance Standards
    Encryption is required or strongly recommended under HIPAA, PCI DSS, NIST, and GDPR.
  • Reduces Insider Threat Risk
    Only users with the proper keys and permissions can access sensitive data.
  • Secures Hybrid Environments
    From on-premises to multi-cloud setups, encryption provides consistent protection.
