CSA STAR: Cloud Security Alliance Security, Trust, Assurance and Risk programme

Cloud assurance based on the Cloud Controls Matrix, from self-assessment to third-party certification.

CSA STAR offers levels from a published self-assessment against the Cloud Controls Matrix (CCM) to third-party STAR Certification (with ISO 27001) and STAR Attestation (with SOC 2). We help cloud providers complete the CAIQ and pursue certification.

Who it is for

  • Cloud and SaaS providers

What you gain

  • A recognised cloud trust signal
  • Reuse of ISO 27001 and SOC 2 work

How we get you ready

  1. Scoping

    Agree the systems, services and criteria in scope, and whether a Type 1 or Type 2 report fits your customers and timeline.

  2. Readiness assessment

    Map existing controls to the criteria, identify gaps and design missing controls with owners and evidence.

  3. Remediation

    Put policies, tooling and processes in place, and rehearse evidence collection so it is routine, not a scramble.

  4. Assessment coordination

    We help you engage the right assessor for your chosen STAR level, prepare the evidence and support you through the assessment and any follow-up actions.

  5. Observation period and report

    For Type 2, we monitor controls through the observation window and help you respond to exceptions before the report is issued.

CSA STAR questions

What is the CAIQ?
The Consensus Assessments Initiative Questionnaire lets providers document which CCM controls they implement; publishing it is STAR Level 1.
