CSA STAR Level 1
CSA STAR (Security, Trust, Assurance, and Risk) is a cloud security assurance program developed by the Cloud Security Alliance (CSA). It helps cloud providers demonstrate the security of their services through a standardized framework built on the Cloud Controls Matrix (CCM).
CSA STAR gives customers a standardized way to evaluate a cloud provider’s security controls. By publishing our CSA STAR Level 1 assessment in the CSA STAR Registry, Nebius provides transparent, standardized information that supports customer security reviews and vendor due diligence.
CSA STAR Level 1 is based on a self-assessment. Nebius completed the CSA Consensus Assessments Initiative Questionnaire (CAIQ), which maps our security controls against the CSA Cloud Controls Matrix (CCM).
The completed assessment is published in the CSA STAR Registry.
