TL;DR: Vendor questionnaires work best when they match a supplier’s access, data exposure, and role, according to Panorays. Self-reported answers need evidence checks or they can create false confidence when vendors and their supply chains change.
Editorial analysis by NHI Mgmt Group, based on content published by Panorays: “The Questions You Need in a Security Questionnaire”.
Key questions
Q: Why do vendor questionnaires need independent validation?
A: Because questionnaire answers are self-reported statements, not proof of control effectiveness.
Q: What are the main failure modes in third-party risk questionnaires?
A: The biggest failures are overbroad templates, missing subcontractor questions, weak evidence review, and treating one-time onboarding as sufficient.
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.
Practitioner guidance
- Build tiered vendor questionnaires by risk class Separate high-impact vendors, cloud service providers, AI-enabled suppliers, and low-access tools into different question sets so the questionnaire reflects actual exposure rather than generic corporate policy.
- Require objective evidence for critical answers Ask for supporting artefacts such as audit reports, penetration test summaries, certifications, and externally observable security findings before accepting claims about access, resilience, or incident readiness.
- Extend review to fourth parties and subcontractors Include questions on subcontractor use, onward data access, and notification obligations whenever the vendor can delegate work or route data through another provider.
Bottom line: Vendor security questionnaires work best when they are matched to the supplier’s actual access, data exposure, and business role rather than applied as a universal template.

Risk-based questionnaires are now a governance control, not a procurement formality. The article correctly treats third-party assessment as a control-selection problem rather than a universal checklist problem. Once vendors span cloud hosting, subcontractors, and AI-enabled processing, the old assumption that every supplier should answer the same questions stops holding. For IAM and NHI teams, the important point is that questionnaire design now influences access decisions, offboarding scope, and trust boundaries, so the control must be tuned to the actual relationship.
A few things that frame the scale:
- 92% of organisations expose NHIs to third parties, raising concerns about supply chain security, according to the Ultimate Guide to NHIs.
- 43% of security professionals are concerned about AI systems learning and reproducing sensitive information patterns from codebases, according to the State of Secrets in AppSec.
A question worth separating out:
Q: When should organisations prioritise fourth-party and AI questions over generic security checks?
A: They should prioritise them whenever a vendor can route data, credentials, or decisions through other providers or model services. In those cases, the real risk sits beyond the immediate supplier, and generic security questions will miss the delegated trust path that actually matters.
