CSA Star Attestations
Validate cloud security practices and support transparency through the Cloud Security Alliance STAR program.
At Insight Assurance, we deliver CSA STAR attestation services that help organizations evaluate the security posture of cloud service providers. Whether you’re a provider seeking independent validation or an enterprise assessing vendor risk, our assessments bring clarity, consistency, and trust to your cloud ecosystem.
What Is CSA STAR Attestation?
The Cloud Security Alliance’s Security, Trust & Assurance Registry (STAR) program enables cloud providers to demonstrate alignment with the Cloud Controls Matrix (CCM) — a comprehensive set of cloud security best practices. It combines an independent third-party assessment with public transparency, helping stakeholders make informed decisions about cloud security.
CSA STAR Attestation is built on top of a SOC 2 Type 2 report and maps controls against CCM requirements, offering a higher level of detail and assurance.
Why Conduct a CSA STAR Attestation?
A CSA STAR attestation strengthens both transparency and trust in how cloud providers manage data, risk, and infrastructure.
Key Benefits:
Greater Cloud Visibility
Gain a clear view into the provider’s security controls and practices.
Informed Vendor Decisions
Use verified data to assess cloud providers against your security expectations.
Risk Mitigation
Understand how providers protect sensitive information, detect threats, and manage vulnerabilities.
Compliance Alignment
Support internal or regulatory requirements related to cloud service oversight.
