Cloud PKI Migration Services

Future‑proof your Public Key Infrastructure (PKI) with a vendor‑neutral partner. SafeCipher designs and delivers cloud PKI migrations that modernise Microsoft AD CS, EJBCA and private CAs; integrate AWS ACM Private CA, Azure Key Vault/Managed HSM, and Google CAS; and automate certificate lifecycle management (ACME/EST/SCEP/CMP) across apps, edge, and Kubernetes.

Why Move PKI to the Cloud? (Scalability, Resilience, Compliance)

  • Elastic scale & HA across regions/AZs; automated backups and DR
  • Proximity to workloads (cloud & edge) to reduce latency for issuance
  • Operational efficiency via APIs, infrastructure‑as‑code, and CLM automation
  • Compliance with GDPR/UK GDPR, NIS2, PCI DSS 4.0, ISO/IEC 27001 using evidence‑ready controls

Target Platforms We Implement (Vendor‑Neutral)

  • AWS: ACM Private CA (PCA), CloudHSM/KMS, PrivateLink, CloudFront/ALB/API Gateway integration
  • Azure Key Vault (AKV) & Managed HSM, App Service/Front Door, Azure AD CBA, ExpressRoute/Private Link
  • Google Cloud: Certificate Authority Service (CAS), Cloud HSM/KMS, Cloud Load Balancing
  • Private PKI: EJBCA, Microsoft AD CS, Entrust CSP PKI; control planes like Keyfactor and Venafi/CyberArk

Reference Architectures (Hybrid by Default)

  • Hybrid Root/Issuing: offline root CA on HSM (on‑prem); issuing CAs in cloud near workloads; CRL/OCSP HA
  • Service Mesh & K8s: cert‑manager with SPIFFE/SPIRE issuers; short‑lived mTLS for services; GitOps pipelines
  • Edge/IoT: offline RAs, ACME/EST at gateways, constrained network CRL strategies

End‑to‑End Migration Playbook (Assessment → Pilot → Scale)

1) Assessment & Planning

  • Inventory CAs, templates/profiles, issuance flows, cert stores, apps, devices, and dependencies
  • Risk & compliance mapping (NCSC, NIST, ISO/IEC 27001, PCI, NIS2) and crypto policy gap analysis

2) Cloud Provider & Topology Selection

  • Compare AWS PCA vs Azure AKV/MHSM vs Google CAS vs private CA; choose tenancy & sovereignty model
  • Decide on‑prem root with cloud issuing, or cloud‑only for specific domains

3) Design & Architecture (HSM, Networking, CLM)

  • HSM custody model (Thales Luna, Entrust nShield, Azure MHSM, AWS CloudHSM) with M‑of‑N ceremonies
  • Private networking (Direct Connect/ExpressRoute/Interconnect), mTLS to HSMs/issuers, IP allow‑lists
  • CLM patterns: ACME/EST/SCEP/CMP, approvals, change windows, monitoring & alerting

4) Data Classification & Encryption

  • Map data to encryption patterns (TLS 1.3, AES‑GCM, ChaCha20‑Poly1305, envelope encryption via KMS)
  • Secrets governance (Vault/AKV/KMS), rotation SLAs, escrow & recovery

5) Migration Strategy (No‑Downtime Cutovers)

  • Blue/green issuance, parallel intermediates, staged template/profile migration
  • Canary renewals during maintenance windows; rollback plans and runbooks

6) Testing & Validation

  • Functional, scale, and latency tests; p95/p99 issuance SLOs; failure injection and DR drills
  • Linting (x509/cabundle), path validation across OS, load balancers, clients, and devices

7) Training & Documentation

8) Operate & Optimise

  • Monitoring: issuance rates, failure ratios, CRL/OCSP health, HSM metrics
  • Cost optimisation: CA hierarchy choices, request/throughput modelling, reserved capacity where applicable

Certificate Use Cases We Cover (Breadth & Depth)

  • TLS for apps/edge/CDN: ALB/ELB, Front Door/CloudFront; OCSP stapling, HSTS guidance
  • Device & user identity: EAP‑TLS for Wi‑Fi/VPN, CBA for portals/SaaS, S/MIME
  • Kubernetes mTLS: service identity, ingress/egress certs, mesh integration
  • Code & document signing: EV code signing, timestamping (TSA), LTV and notarisation

Policy, Governance & Compliance (Evidence‑Driven)

  • Update Crypto Policy and Key Management Standard (algorithms, key sizes, validity, rotation)
  • Map controls to ISO/IEC 27001, PCI DSS 4.0, NIS2, sector requirements; maintain traceability matrices

Post‑Quantum & Crypto‑Agility

  • Define crypto‑agility patterns and deprecation schedules (RSA/ECDSA lifetimes)
  • Pilot hybrid approaches where supported; plan migration for PQC KEMs (e.g., Kyber) and ML‑DSA signing in internal domains

Why SafeCipher (Vendor‑Neutral, Outcome‑Driven)

  • Vendor‑neutral advice; deep experience across AWS, Azure, Google, AD CS/EJBCA, Keyfactor, Venafi/CyberArk
  • No‑drama cutovers: runbooks, canaries, and automated renewals prevent outages
  • Audit‑ready ops: ceremony packs, immutable logs, evidence for regulators and boards

FAQ — Cloud PKI Migration

  • Will we have downtime? No—blue/green issuance, canaries, and rollback plans avoid service disruption.
  • Can we keep our root on‑prem? Yes—typical design is on‑prem root with cloud issuing CAs.
  • What about sovereignty? We align to residency and regulator expectations, or use sovereign regions / on‑prem anchors.
  • How do we handle devices and legacy apps? We stage templates/profiles, provide shims, and run parallel chains until cutover.
