Azure Managed HSM

Azure Managed HSM is a cloud service for managing cryptographic keys backed by hardware security modules. It supports customer-managed keys, automatic key rotation, audit logs and key import through a web-accessed service. Both listed key types are supported. The Standard B1 plan is a Managed HSM pool billed by hourly usage fee per HSM pool; no price is provided. Azure lists no free plan. The cloud deployment model suits organisations that want managed HSM capabilities rather than a self-hosted installation. Key import allows existing keys to be brought into the service, while automatic rotation handles scheduled key changes. Audit logs provide activity records for review. Teams evaluating the service can focus on whether HSM-backed protection, customer control, import, rotation and logging meet their key-management needs, and whether hourly pool billing fits their usage.

Azure Managed HSM suits organisations needing cloud-hosted HSM-backed, customer-managed keys with rotation, import and audit controls. It is intended for teams comfortable with paid, hourly pool billing.
