Cloud PKI: Select a Provider and Plan Migration

Cloud PKI describes an operating model here, not a single product with guaranteed features. The decision starts with certificate users, trust boundaries and integrations. We turn these into a requirements catalogue and assess suitable offers. Complete CA infrastructure implementation or a product-specific Intune deployment can follow as a separate assignment.

ADVISORI supports the selection and adoption of a hosted PKI. We compare providers against your applications, clarify key and operating responsibilities, and test a suitable migration approach in a pilot.

6 service modules

What we take on for you

Bookable individually or as an end-to-end programme.

01

Requirements and Provider Comparison

We make offers comparable against the same needs catalogue.

  • Identify certificate users and use cases
  • Define mandatory criteria and exclusions
  • Map product evidence and open questions
  • Document the decision and alternatives
02

Responsibilities and Key Protection

We clarify tasks shared between the provider and your teams.

  • Record key ownership and access rights
  • Assess operating and security evidence
  • Assign change and approval authority
  • Separate contractual commitments from test results
03

Integration and Automation

We test the interfaces required by your applications.

  • Identify the actual enrollment methods
  • Test installation and application trust
  • Limit automation permissions
  • Plan error handling and logging
04

Pilot and Migration

We develop a transition from the existing environment.

  • Record CA and application dependencies
  • Agree pilot scope and success criteria
  • Assess coexistence and fallback options
  • Retire legacy systems only after approval
05

Operations and Provider Oversight

We organise day-to-day monitoring and collaboration.

  • Observe certificate and service state separately
  • Agree support and escalation routes
  • Walk through specific incident scenarios
  • Track outstanding actions and tests
06

Costs and Provider Exit

We assess effort beyond initial deployment and operation.

  • Make subscription and usage assumptions explicit
  • Include integration and operating effort
  • Assess exit dependencies and data access
  • Update comparisons when assumptions change

5 phases

Our Approach to Cloud PKI Services

Deliverables include a documented provider assessment, a responsibility matrix, a cost model with explicit assumptions and a pilot or migration plan. Product features are assessed using current evidence and selected tests. Untested integrations, remaining legacy systems and future switching requirements remain visible in the results.

  1. Record applications and certificate needs

  2. Agree responsibilities and selection criteria

  3. Compare offers and integration evidence

  4. Test pilot and migration steps

  5. Document the decision and operating boundaries

Cloud PKI as an Enabler for Digital Transformation

Compare the exit path too: which trust anchors, certificates, interfaces and operating records would need replacement or continuity when changing providers?

18 QUESTIONS, BRIEFLY ANSWERED

Frequently asked questions about Cloud PKI: Select a Provider and Plan Migration

Which decision does this service support?

It supports selection of a hosted PKI operating model and the planned transition to it. We assess whether an offer fits your applications and responsibilities. The result is a reasoned decision with conditions, not an automatic recommendation to move to the cloud.

How does Cloud PKI differ from Microsoft Cloud PKI?

Cloud PKI is a broad service category. Microsoft Cloud PKI is a specific service for an Intune scenario. We therefore start with the use case, then assess a product candidate against its actual boundaries and the required integration.

Which applications need to be recorded?

We identify systems that request, install or validate certificates and the teams operating them. This includes infrequently updated or intermittently connected applications. The inventory helps expose trust dependencies that a seemingly simple CA change could otherwise overlook.

How are providers compared?

Each candidate is assessed against the same mandatory and scored criteria. Product documentation, contractual commitments and pilot results are shown separately. Open questions have owners; an overall score does not conceal missing evidence.

Is HSM protection identical across offers?

No. We assess the actual key model, administrative rights and supporting evidence within its stated scope. A general product label is insufficient. Your team’s remaining responsibilities are documented rather than assuming complete protection from the hosting model alone.

How are shared responsibilities defined?

The responsibility matrix assigns issuance, permissions, changes, monitoring and incident handling. Each boundary has a responsible team. This makes clear before contracting which activities are purchased and which remain internal.

What integration evidence is expected?

We select representative applications and test the full path from request to use. Renewal and error handling are also planned. An available API endpoint or successful issuance alone does not establish a usable integration.

How are CI/CD and automation assessed?

We identify the process needing certificates, its identity and its permission boundaries. Errors, secrets and logs receive an explicit operating design. Automation is tested on selected workflows; compatibility with every pipeline is not assumed.

What matters for Kubernetes and short-lived workloads?

We assess workload identity, lifetime, ownership and actual certificate use. We then examine the provider’s supported integration and the intended renewal or replacement process. The product name alone does not demonstrate a suitable cluster integration.

How is migration prepared?

Existing certificates, trust anchors and application dependencies are recorded first. These inform sequencing, the pilot and acceptance criteria. Old components are retired only after remaining use has been assessed. Planned coexistence has an explicit end state and accountable owners.

What does the pilot establish?

The pilot tests agreed use cases and relevant failure conditions. Results are recorded with configuration and scope. Passing the pilot establishes only that scope; additional platforms or greater load require their own evidence before acceptance.

How is monitoring planned?

We distinguish individual certificate state from provider-service and connected-application health. Each observation has an owner and a response. Reports and alerts are described in the operating design according to the information they actually provide.

How are availability and recovery assessed?

Contractual objectives are compared with dependencies and your own response options. We walk through selected outage scenarios and document required procedures. A service-level commitment replaces neither a recovery test nor evidence of uninterrupted application operation.

How are scale and performance assessed?

Assessment uses a defined load profile and measurable criteria for your use cases. Provider limits and test conditions are retained in the results. Unlimited scaling or general speed improvements are not inferred from the cloud operating model.

How are total costs compared?

The model includes usage, licensing, integration, internal operating work and a possible exit. Assumptions are explicit, with scenarios where uncertainty matters. Savings are a result of the actual comparison, not an inherent property of every hosted PKI.

What should an exit plan contain?

It records data access, remaining trust relationships, interfaces and replacement tasks. Key or configuration transferability is assessed for the actual offer. Where transfer is unavailable, the plan needs to address replacement and transition.

Does provider selection establish regulatory compliance?

No. Requirements are related to the actual use with the responsible specialists. Evidence and open issues are mapped transparently. A provider decision or technical pilot acceptance is neither certification nor a comprehensive legal assessment.

How is the decision reviewed later?

We agree review triggers such as changes to applications, costs, contract terms or product boundaries. Original assumptions remain traceable. The team can then assess changes deliberately rather than treating every product announcement as a reason to migrate immediately.
