What is Encryption at Rest?

Encryption at rest protects stored data by encrypting it on disk, in databases, or in storage systems, ensuring data confidentiality even if storage media is physically compromised.

Encryption at rest refers to the encryption of data while it is stored on any persistent storage medium—hard drives, SSDs, databases, cloud storage, or backup media. This protects against unauthorized access to data through physical theft, unauthorized storage access, or improper media disposal.

Encryption at rest is a baseline security expectation under most privacy regulations and is specifically referenced in HIPAA Security Rule technical safeguards. ProtectIQ supports transparent encryption at rest for databases and file systems with centralized key management.
