CSA STAR

What is CSA STAR?

CSA STAR is a widely recognised security assurance programme for cloud services, designed to help organisations evaluate the security posture of cloud providers.

CSA STAR is a public registry where cloud service providers (CSPs) publish their security and compliance information.

It is managed by the Cloud Security Alliance (CSA), a non-profit organisation that promotes best practices for cloud security.

The purpose of CSA STAR is to increase transparency and trust in cloud services by giving customers insight into how providers address security, privacy, and compliance.

There are three levels of assurance:

  • Level 1 – Self-Assessment: Provider completes the Consensus Assessments Initiative Questionnaire (CAIQ) or Cloud Controls Matrix (CCM).

  • Level 2 – Third-Party Audit: Independent audits based on recognised standards like ISO/IEC 27001, SOC 2, or GB/T 22239.

  • Level 3 – Continuous Monitoring: Ongoing automated security monitoring.

Our CSA STAR Consultancy Services

We help cloud service providers (CSPs) and cloud customers prepare for and achieve CSA STAR certification/attestation.

CSA STAR Readiness Assessment (Gap Analysis)

The CSA STAR gap analysis covers the following areas:

  • Project scoping, determining which cloud services, business units, or geographies are in play.

  • Identify whether the target is STAR Level 1 (Self-Assessment), Level 2 (Third-Party Audit), or Level 3 (Continuous Monitoring).

  • Review existing documents and certifications and check if current compliance efforts (ISO 27001 2022) meet STAR requirements.

  • Compare current security controls to the CSA Cloud Controls Matrix (CCM).

  • Identify gaps in areas such as data security & encryption, identity & access management etc.

  • Conduct workshops/interviews with IT, security, compliance, and business stakeholders.

  • Highlight non-conformities, partial implementations, or missing controls and assess severity/impact.

  • Provide prioritised recommendations to close gaps.

  • Deliver a formal report with current compliance status, gap analysis results, STAR readiness score and action plan for certification.
