The CSA STAR (Cloud Security Alliance Security, Trust & Assurance Registry) is a globally recognized cloud security certification framework designed to evaluate and enhance the security capabilities of cloud service providers. It is based on the Cloud Security Alliance’s Cloud Controls Matrix (CCM) framework, integrated with the ISO/IEC 27001 Information Security Management System, providing an independent assessment standard for the security and transparency of cloud services. CSA STAR certification is divided into three levels: self-assessment, third-party certification, and continuous monitoring. By obtaining CSA STAR certification, cloud service providers can demonstrate their commitment to security, transparency, and compliance, offering greater trust to customers and enabling businesses to confidently select and utilize cloud services.
