CAIQ v4 Response Guide: Question Patterns, Evidence Mapping, and What Buyers Actually Want

The Cloud Security Alliance's CAIQ (Consensus Assessments Initiative Questionnaire) v4 is one of the most common security questionnaires in B2B SaaS sales. At 261 questions across 16 domains, it's thorough — but it's also highly structured, which makes it systematizable.

This guide covers how the CAIQ v4 is organized, where teams spend the most time, and how to build a canonical answer set that makes future CAIQ responses routine.

CAIQ v4 Structure: 16 Domains

The CAIQ v4 is organized around the Cloud Controls Matrix (CCM) v4. The domains are:

| Code | Domain | |------|--------| | A&A | Audit & Assurance | | AIS | Application & Interface Security | | BCR | Business Continuity Management | | CCC | Change Control & Configuration Management | | CEK | Cryptography, Encryption & Key Management | | DSP | Data Security & Privacy Lifecycle Management | | GRC | Governance, Risk & Compliance | | HRS | Human Resources | | IAM | Identity & Access Management | | IPY | Interoperability & Portability | | IVS | Infrastructure & Virtualization Security | | LOG | Logging & Monitoring | | SEF | Security Incident Management, E-Discovery & Cloud Forensics | | STA | Supply Chain Management, Transparency & Accountability | | TVM | Threat & Vulnerability Management | | UEM | Universal Endpoint Management |

The CAIQ Lite: When Buyers Send the Short Version

The CAIQ Lite (138 questions) is a subset of the full CAIQ v4 that covers the highest-priority controls. If a buyer sends you the CAIQ Lite, focus your energy here — a well-prepared CAIQ Lite answer set will cover ~53% of the full v4 questions.

Most teams in early enterprise sales cycles will encounter the CAIQ Lite first. Build your canonical answer set to cover the full v4 and the Lite is done automatically.

Evidence Mapping by Domain

High-confidence domains (A&A, GRC, HRS)

A&A (Audit & Assurance) questions center on your SOC 2 or ISO 27001 audit: when was your last audit, who performed it, what did it cover? If you have a SOC 2 Type II report, most A&A questions are answered.

GRC (Governance, Risk & Compliance) questions focus on your risk management program — risk assessments, policy review cadence, compliance obligations. Your information security policy and risk register are the key evidence.

HRS (Human Resources) questions ask about security awareness training, background checks, and employee offboarding. HR policies and training completion records cover most of these.

Technical-depth domains (IAM, IVS, TVM)

IAM (Identity & Access Management) is where teams often spend the most time. Questions cover MFA, privileged access, access reviews, and offboarding. Your access control policy + SOC 2 report (CC6 family of controls) maps well here.

IVS (Infrastructure & Virtualization Security) questions require specific answers about your cloud infrastructure, network segmentation, and virtualization approach. Your architecture documentation is essential.

TVM (Threat & Vulnerability Management) asks about vulnerability scanning cadence, penetration testing, and patch management. Current pen test summaries and vulnerability scanning documentation are your evidence.

The harder domains (CEK, DSP, LOG)

CEK (Cryptography, Encryption & Key Management) requires specificity: algorithm standards (AES-256, RSA-2048, etc.), key rotation policies, and certificate management. Generic "we encrypt data" answers don't pass here.

DSP (Data Security & Privacy Lifecycle Management) has expanded significantly in v4, covering data classification, retention, and deletion — plus privacy-specific obligations. Your data classification policy and privacy notice are key.

LOG (Logging & Monitoring) asks for specifics on log retention periods, alerting thresholds, and SIEM capabilities. Your SOC 2 report (CC7 family) helps, but operational specifics often need current answers.

Question Patterns to Know

The CAIQ uses a consistent question structure. Most questions follow the pattern:

"Do you [control description]?"

And the expected answer is "Yes" or "No" with a clarification field.

The key insight: buyers aren't just checking the Yes/No. They're checking:

1. Is this answer consistent with your SOC 2 report?
2. Does your clarification add specificity?
3. Is the answer consistent with what you've told other buyers?

A "Yes" with a vague clarification often triggers more follow-up than a "Yes" with a specific, evidence-linked explanation.

Building Reusable CAIQ Answers

The 80% of CAIQ questions that appear across every buyer's version are answered the same way every time. Building a canonical CAIQ answer set means:

1. Draft answers for every CCM control — yes/no plus a 1-3 sentence clarification
2. Link each answer to evidence — which document supports this claim?
3. Date-stamp evidence — when was the SOC 2 report issued? When was the pen test performed?
4. Schedule review triggers — which answers change when your SOC 2 renews? When you change cloud providers?

Once you have this library, a new CAIQ response is a review task, not a drafting task.
