What Is the CAIQ?

The Consensus Assessments Initiative Questionnaire (CAIQ) is a standardized security assessment developed by the Cloud Security Alliance (CSA). It provides a comprehensive set of questions that cloud service providers can use to document their security controls, and that cloud customers can use to evaluate potential vendors.

The CAIQ v4 contains 261 questions organized across 17 control domains, making it one of the most thorough cloud security assessments available. It's based on the CSA Cloud Controls Matrix (CCM), which maps to major compliance frameworks including SOC 2, ISO 27001, NIST, GDPR, and HIPAA.

Why the CAIQ Matters

  • Industry standard — Used by thousands of organizations worldwide for cloud vendor evaluation
  • CSA STAR registry — Completing the CAIQ qualifies you for the CSA STAR Level 1 listing, a publicly visible trust signal
  • Framework mapping — Answers map directly to SOC 2, ISO 27001, and other frameworks, reducing duplicate work
  • Enterprise requirement — Many enterprise procurement teams specifically request CAIQ completion

How to Answer the CAIQ Efficiently

Strategy 1: Map to Existing Compliance Work

If you already have SOC 2 or ISO 27001 certification, many CAIQ answers can be derived directly from your existing documentation:

CAIQ DomainSOC 2 MappingISO 27001 Mapping
IAMCC6.1-CC6.3A.9 Access Control
CEKCC6.1, CC6.7A.10 Cryptography
BCMA1.2, A1.3A.17 BC Management
SEFCC7.3-CC7.5A.16 Incident Mgmt
HRSCC1.4, CC1.5A.7 Human Resource

Strategy 2: Use a Response Template

For each question, structure your response with:

  1. Direct answer — Yes/No or the specific control
  2. Implementation details — How the control works in practice
  3. Evidence reference — Point to the relevant policy or certification

Strategy 3: Automate with AI

With TrustFill AI, you can:

  1. Upload your SOC 2 report, ISO 27001 documentation, and security policies
  2. Import the CAIQ spreadsheet
  3. Let AI auto-generate responses mapped to your documentation
  4. Review confidence scores and refine answers
  5. Export the completed CAIQ in the standard CSA format

This reduces completion time from 2-3 weeks to 1-2 days.

Tips for High-Quality CAIQ Responses

  1. Be specific — Don't just say "Yes." Describe the control, tool, or process.
  2. Reference evidence — Cite your SOC 2 report section, policy document, or certification.
  3. Note compensating controls — If you don't meet a requirement exactly, explain your alternative.
  4. Update regularly — The CAIQ should reflect your current security posture, not last year's.
  5. Use consistent language — Align terminology with the CCM framework.

Publishing to CSA STAR

Once completed, submit your CAIQ to the CSA STAR Registry for public listing:

  1. Complete the CAIQ self-assessment
  2. Submit to CSA via the STAR registry portal
  3. Your company appears in the public registry with your completed CAIQ
  4. Share the STAR listing URL with prospects as a trust signal

This is a free, high-value trust signal that demonstrates transparency to potential customers.
