TL;DR: Vendor security assessments fail when they rely on questionnaires alone, because the real control point is third-party access inside your environment, according to Securden. That shifts the programme from paper review to scoped access, session evidence, and revocation discipline across the vendor lifecycle.
NHIMG editorial — based on content published by Securden: vendor security assessments and the identity controls that shape them
By the numbers:
- 80% faster deployment is the pace Securden says organisations can achieve by consolidating vendor access controls on one platform.
Questions worth separating out
Q: What breaks when vendor assessments rely on questionnaires instead of access evidence?
A: They break at the point where paper controls diverge from actual exposure.
Q: Why does third-party access create more risk than a simple approval workflow suggests?
A: Because approval does not equal containment.
Q: How do security teams know whether vendor access is actually governed?
A: They should be able to answer three questions without delay: who has access, what they can reach, and how quickly access can be removed everywhere it exists.
Practitioner guidance
- Map assessment findings to live access records Cross-check vendor questionnaire responses against actual entitlements, active sessions, and recent approval history so the assessment reflects what the vendor can really reach.
- Time-box all third-party privileged access Grant vendor access only for the approved task window, then revoke it automatically when the window closes rather than leaving it to manual follow-up.
- Require command-level session evidence Store recordings or command trails for every privileged vendor session so investigators can reconstruct activity without relying on vendor self-reporting.
What's in the full article
Securden's full analysis covers the operational detail this post intentionally leaves for the source:
- How its vendor access management workflow scopes third-party access without revealing credentials
- How session recordings, keystroke trails, and live shadowing support audit and incident review
- How the platform maps vendor access reporting to SOX, NIST, HIPAA, PCI DSS, and CMMC requirements
- How unified PAM, password management, and endpoint privilege management reduce admin overhead

Vendor access is the assessment control that matters most. Questionnaires can describe a vendor's posture, but they do not tell you how much damage that vendor can do once access is granted. The article is right to centre access control, because the risk is created in the live identity plane, not in the document set. For practitioners, the practical conclusion is that assessment evidence must include access scope, session records, and revocation state.
A few things that frame the scale:
- Only 1.5 out of 10 organisations are highly confident in their ability to secure NHIs, according to The State of Non-Human Identity Security.
- 85% of organisations lack full visibility into third-party vendors connected via OAuth apps, according to The State of Non-Human Identity Security.
A question worth separating out:
Q: Should organisations compare vendor risk scores with actual privileged access controls?
A: Yes. Risk scores are useful for prioritisation, but they do not replace control evidence. An organisation should compare the score with the vendor's access scope, monitoring depth, and offboarding discipline, because those operational controls determine whether the third party can actually cause harm inside the environment.
