CSA STAR — Security, Trust, Assurance, and Risk Program
SmartSuite provides the system for managing controls, evidence, mappings, assessments, and reporting. Framework text may require a separate license unless explicitly provided.
Overview
CSA STAR (Security, Trust, Assurance, and Risk) is a cloud security assurance program providing transparency and independent verification of cloud service provider security practices through self-assessment, third-party certification, and continuous monitoring.
Why it Matters
- Demonstrate cloud security transparency
Provide customers and auditors with structured visibility into cloud security controls and practices.
- Enable customer trust
Show prospective cloud customers that security practices have been independently assessed against the CSA CCM.
- Support procurement decisions
Help organizations evaluate and compare cloud provider security postures through standardized assessment.
- Reduce customer audit burden
Allow customers to rely on STAR assessments reducing individual security assessment requests.
How it Works
CSA STAR has three levels: Level 1 (self-assessment via CAIQ), Level 2 (third-party certification based on ISO 27001 or SOC 2 with CSA CCM), and Level 3 (continuous monitoring). Cloud providers submit assessments to the publicly accessible STAR Registry.
Key Elements
- Cloud Controls Matrix (CCM)
Provides the security control framework used for STAR assessments covering 17 cloud security domains.
- Consensus Assessments Initiative Questionnaire (CAIQ)
Enables Level 1 self-assessment through standardized cloud security questionnaire.
- STAR Registry
Public registry where cloud providers publish their STAR assessments for customer review.
Framework Scope
CSA STAR applies to cloud service providers seeking to demonstrate security transparency and organizations evaluating cloud provider security for procurement decisions.
Framework Objectives
- Provide transparent cloud security assurance through standardized assessment

Frequently Asked Questions For CSA STAR (Security, Trust, Assurance, and Risk)
CSA STAR is used to assess, validate, and demonstrate the security and compliance posture of cloud service providers. It provides a structured methodology for evaluating cloud controls and facilitating trust between providers, customers, and third-party assessors.
CSA STAR certification is not mandatory but is increasingly requested by customers and regulators as part of supplier due diligence and cloud risk management. Organizations may choose between self-assessment and independent third-party certification depending on their compliance needs and market demands.
CSA STAR applies to cloud service providers and organizations seeking to evaluate or assure cloud security practices. It covers a broad range of security domains including data protection, privacy, governance, and operational resilience across all cloud deployment models.
Key artifacts include the Cloud Controls Matrix (CCM), which lists required controls, the Consensus Assessments Initiative Questionnaire (CAIQ) for self-assessment, and entries within the CSA STAR Registry. These facilitate structured assessment and transparent reporting of cloud security practices.
Organizations implement CSA STAR by mapping their cloud security controls to the CCM, completing the CAIQ for self-assessment, and pursuing third-party audits if seeking higher assurance levels. Continuous control monitoring, regular risk assessments, and evidence collection are integral to ongoing program maintenance.
CSA STAR is designed to align with industry standards such as ISO 27001 and NIST by mapping CCM controls to these frameworks. This approach allows organizations to leverage their existing compliance efforts and streamline cloud-specific reporting and assessments.
Ongoing compliance involves periodically reviewing control effectiveness, updating risk assessments, maintaining accurate CAIQ documentation, and addressing identified gaps. Third-party certifications typically require annual surveillance or recertification to ensure continual adherence to evolving standards.
SmartSuite supports CSA STAR by providing control libraries mapped to CCM, risk register management, and automated evidence collection processes. The platform facilitates CAIQ completion, tracks audit artifacts, and enables remediation workflows, audit readiness, and real-time compliance reporting for regulatory and executive oversight.
