Reviewing vendor security questionnaires requires claim-by-claim evidence mapping to identify unsupported statements, contradictions, and outdated attestations. This process checks each response against attached artifacts, flagging hedge words and missing evidence before finalizing a risk decision.

Analyzing SIG Lite or CAIQ responses involves comparing vendor answers against attached evidence and attestations to surface contradictions. A skeptical review identifies scope mismatches, verifies artifact freshness, and outputs a findings report with follow-up questions rather than an approval verdict.

Verifying SOC 2 and ISO 27001 attestations requires checking the vendor's claims against the actual scope and dates of the reports. This scrutiny exposes stale evidence, scope mismatches, and unsupported security statements to ensure the attestation accurately covers the services in question.

Assessing AI vendor questionnaires requires scrutinizing no-train commitments, data residency, sub-processors, retention, and model-versioning language. This AI-specific review verifies that contract terms and data-flow disclosures align with the vendor's security claims.

Yes, this skeptical review approach applies to custom third-party security reviews for SaaS and AI vendors handling sensitive data. It maps claims to evidence, checks for hedge words, and verifies artifact authenticity across custom formats alongside standard frameworks.

A vendor risk review outputs findings instead of an approval verdict to force evidence-based decision-making. By returning only unsupported claims, contradictions, and follow-up questions, the review prevents rubber-stamping and ensures all gaps are addressed before procurement.
