TL;DR: Third-party risk management questionnaires help standardize vendor security, compliance, and operational checks across onboarding, reassessment, and renewal, while automation and risk scoring improve consistency and monitoring, according to SecurEnds. The deeper issue is that questionnaires can document trust, but they do not prove control effectiveness without evidence and continuous validation.

By the numbers:
- 72% of organisations have experienced or suspect they have experienced a breach of non-human identities, with 46% confirmed and 26% suspected.
Questions worth separating out
Q: How should security teams use third-party risk questionnaires in vendor onboarding?
A: Use them to set an initial risk baseline, but require evidence before granting access to sensitive systems or data.
Q: Why do vendor questionnaires fail to reduce risk on their own?
A: They rely on self-reported answers, so they can show what a vendor says it does without proving what actually happens in production.
Q: What do organisations get wrong about questionnaire-based vendor risk management?
A: They often confuse completion with control.
Practitioner guidance
- Tie questionnaire updates to lifecycle events Refresh vendor risk reviews at onboarding, renewal, reassessment, and any material service change so access decisions track the actual business relationship.
- Demand evidence for every high-risk answer Require artefacts such as audit reports, access logs, incident procedures, or certification records before accepting any claim that affects data or identity risk.
- Map questionnaire sections to identity ownership Assign each control domain to a named internal owner, including third-party access, privileged accounts, and subcontractor exposure, so findings do not stall in review.

Questionnaires create governance theatre when they are treated as proof. A completed response set can make vendor risk feel controlled, but it only documents intent unless the organisation validates the claims with evidence. That is why the control problem is not questionnaire design alone. The control problem is the gap between attestation and operational reality, especially where vendor access becomes non-human identity access inside shared delivery chains. Practitioners should treat the questionnaire as input to governance, not as governance itself.
A few things that frame the scale:
- 85% of organisations lack full visibility into third-party vendors connected via OAuth apps, according to The State of Non-Human Identity Security.
- The average organisation believes more than 1 in 5 of their non-human identities are insufficiently secured, according to The 2024 ESG Report: Managing Non-Human Identities.
A question worth separating out:
Q: How can teams make vendor risk questionnaires more effective over time?
A: Tie them to lifecycle events, keep them short enough to get reliable responses, and update the control set when the vendor’s services or risk profile changes. A questionnaire that evolves with the relationship is far more useful than a static annual form.
