Cloud Migration — PKI, KMS & Security Architecture

Plan and execute migrations to Azure, AWS and Google Cloud with robust PKI architecture, cloud HSM patterns, key custody and cryptographic audits. We design for availability, compliance and crypto-agility.

Strategy & discovery

  • Current-state inventory across identities, certs, keys, data sensitivity, apps and dependencies — start with a cryptographic audit.
  • Target operating model for cloud identity, secrets, certificates and HSM custody.
  • Landing zone guardrails and shared services for PKI/CLM, KMS and logging.

Identity, PKI & certificates

  • Design/refresh enterprise PKI: offline root, issuing CAs, OCSP/CRL, profiles/EKUs — see PKI design patterns.
  • Lifecycle automation (CLM) with Venafi, Keyfactor or EJBCA; ACME/EST and API issuance.
  • Hybrid cutovers from AD CS; blue/green rollovers and evidence packs for audit.

Data protection & KMS

  • Customer-managed keys with cloud HSM patterns and on-prem anchors (M-of-N ceremonies, separation of duties).
  • Envelope encryption, rotation policies, break-glass controls and immutable logs.
  • Platform coverage: Azure Key Vault & Managed HSM, AWS KMS & CloudHSM, Google Cloud KMS, HashiCorp Vault; compare options at HSM Vendors.

Network & zero trust

  • Mutual-TLS for service-to-service, device identity and workload attestation.
  • Private endpoints, segmented control planes and validated revocation paths.
  • Observability: OCSP freshness, CRL age, expiry MTTR and issuance SLO tracking.

Compliance & evidence

We map technical controls to compliance; you retain legal sign-off.

  • FIPS 140-3 use where policy demands; NIST.
  • PCI DSS 4.x crypto/key management; PCI SSC.
  • GDPR/UK GDPR encryption & key control evidence — GDPR • UK ICO.
  • Future-proofing toward ≥128-bit strength and post-quantum transition.

Migration waves & cutover

  • App grouping by dependency/criticality; shadow and rehearsal environments.
  • Blue/green or in-place rollover; validation and back-out runbooks.
  • Stakeholder comms, change approvals and post-cutover SLO verification.

Cloud migration — FAQ

Do you support hybrid migrations from AD CS?

Yes — we operate parallel hierarchies and cut over via blue/green with OCSP/CRL continuity.

Can you keep customer keys under customer control?

Yes — customer-managed keys with cloud KMS and managed/on-prem HSM anchors; dual-control ceremonies and evidence.

How do you reduce expiry-related outages?

Discovery, CLM automation (Venafi, Keyfactor, EJBCA), standard profiles and active monitoring for revocation/expiry SLOs.
