CSA STAR at Exclaimer

CSA STAR (Security, Trust, Assurance and Risk) is a publicly accessible registry that documents cloud providers' security controls against the Cloud Controls Matrix. Exclaimer's cloud solution has been publicly listed in the CSA STAR Registry since July 2020. Anyone evaluating Exclaimer can download our completed CAIQ (Consensus Assessments Initiative Questionnaire), the standardized questionnaire cloud providers complete to document their security controls against the CCM framework, directly from the Cloud Security Alliance.

This means customers can independently verify Exclaimer's stated security controls through the public registry without requesting documentation directly.

This page covers what's in our submission and how to access it.

Frequently asked questions about Exclaimer and CSA STAR

Is Exclaimer listed in the CSA STAR Registry?

Yes. Exclaimer Cloud has been publicly listed in the CSA STAR Registry since 16 July 2020. The listing includes our completed CAIQ.

Exclaimer holds a STAR Level 1 Self-Assessment. At this level, the provider completes the Consensus Assessments Initiative Questionnaire (CAIQ) against the Cloud Controls Matrix and publishes the result in the public CSA STAR Registry.

The difference is independent audit. Level 1 is a public self-assessment: the provider answers the CAIQ against their own controls and publishes the result in the registry. Level 2 adds an accredited external auditor who assesses the provider against the Cloud Controls Matrix and issues either a STAR Attestation (aligned to SOC 2) or a STAR Certification (aligned to ISO/IEC 27001).

No. Level 1 is a self-assessment. Independent audit applies at Level 2.

The CAIQ covers Exclaimer Cloud's controls across all 17 domains of the Cloud Security Alliance's Cloud Controls Matrix (CCM) v4. The matrix defines 197 control objectives. Our completed questionnaire documents how Exclaimer's cloud solution addresses each one. The 17 domains are:
