CSA STAR evidence across 434 vendors
The CSA STAR registry is a public, scheme-operated list. Level 1 is a self-assessment against the Consensus Assessments Initiative Questionnaire; Level 2 is a third-party certification (ISO 27001 basis) or attestation (SOC 2 basis) against the Cloud Controls Matrix. CertReports mirrors every entry and links it to the vendor page.

Why Level 2 matters for SOC 2
No SOC 2 registry exists. A STAR Level 2 attestation is built on a SOC 2 examination, which makes it the strongest free, registry-grade signal that a SOC 2 report exists.
