Reference patterns

  • Cloud KMS with customer-managed keys (CMK) and on-prem HSM root of trust (BYOK/KEK).
  • Dual-control/M-of-N operations and tamper-evident ceremonies — see our HSM Services.
  • Boundary patterns for multi-tenant apps, data sovereignty and regulated workloads.

Key lifecycle & rotation

  • Inventory, classification, rotation and retirement with attestable audit trails.
  • Envelope encryption (DEK/KEK), crypto posture audits, rollover runbooks.
  • Policy-driven access (RBAC/ABAC), separation of duties, break-glass controls.

Platform integration

  • Azure Key Vault & Managed HSM • AWS KMS & CloudHSM • Google Cloud KMS.
  • HashiCorp Vault (Transit/PKI), Thales & Entrust HSMs, app libraries (CNG, PKCS#11, JCE, OpenSSL).
  • CLM and certificate issuance flows (Venafi, EJBCA, Keyfactor) with key provenance.

Compliance & policy alignment

We align controls and evidence so your compliance/legal teams can demonstrate conformity.

  • FIPS 140-3: Validated modules when policy demands — NIST.
  • PCI DSS 4.x: Key management for PAN data — PCI SSC.
  • GDPR/UK GDPR: Encryption and key control evidence — GDPR • UK ICO.
  • DORA / NIS2: Operational resilience and cryptographic governance — DORA • NIS2.

KMS & HSM — FAQ

Do you support BYOK/KEK and cross-cloud patterns?

Yes — we build envelopes and workflows for Azure, AWS and Google Cloud, with on-prem or managed HSM custody.

How do you prove separation of duties?

M-of-N ceremonies, role segregation (RBAC/ABAC) and immutable evidence artefacts mapped to policy.

Can you integrate with CLM platforms?

Yes — Venafi, Keyfactor and EJBCA are common; we keep key provenance intact through issuance pipelines.
