Azure Key Vault: Managed HSM Deep Dive

Managed HSM provides FIPS 140-2 Level 3 validated hardware security modules. Required for highly regulated workloads (PCI-DSS, HIPAA).

Key Differences from Standard Key Vault

• Single-Tenant HSM: Your keys never share hardware with other customers.
• BYOK: Import your own key material with cryptographic proof of transfer.
• Pricing: ~$3,500/month (vs ~$1/month for standard Key Vault).

Use only when compliance mandates it. Standard Key Vault is sufficient for 99% of use cases.
