Key Vault
Encryption
Managed key/secret storage providing access control, audit trails, versioning, and sometimes HSM-backed protection.
Definition
Key vaults store secrets and keys encrypted and enforce policy-based access, auditing, and rotation. Some provide non-exportable HSM-backed keys and key versioning.
Why this matters
Why it matters: Strong key custody is required for encryption to meaningfully protect privacy.
Example
Example: Store customer-encryption keys in a vault with RBAC, require approvals for export, and rotate keys regularly.
