TL;DR: Third-party access remains a frequent breach path, and Zluri’s guide argues that vendor access management must combine least privilege, monitored sessions, and prompt revocation to reduce exposure, according to Zluri. The real issue is not access enablement but the governance gap between temporary collaboration and durable accountability.
Editorial analysis by NHI Mgmt Group, based on content published by Zluri: “Vendor Access Management: An Ultimate Guide”.
Key questions
Q: What breaks when machine access is managed like employee access?
A: Employee-style access management breaks when it assumes stable identities, predictable sessions, and review cadences that are too slow for workloads or agents.
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 if supplier access governance is failing?
A: A governance failure shows up when you cannot answer three questions quickly: who has access, what data they can reach, and when that access expires.
Practitioner guidance
- Create a third-party identity inventory Catalogue every vendor, contractor, and service provider with the systems they can reach, the business owner, and the date access should end.
- Separate vendor access from employee workflows Use dedicated approval, authentication, and review paths for external identities so employee role models do not silently over-grant access.
- Enforce session monitoring for privileged vendor work Record vendor sessions that can modify files, execute commands, or reach sensitive systems, and make review part of the access process.
Bottom line: Vendor access becomes risky when external identities are governed with employee-centric assumptions that do not match their lifecycle or accountability model.

Third-party identity is the governance gap most IAM programmes still under-model. Vendor access is not simply another user type because its trust boundary, duration, and ownership model are different from employee IAM. The article shows that many organisations still manage vendors through access mechanics while under-investing in lifecycle accountability. The practitioner conclusion is that third-party identity needs its own governance logic, not a borrowed employee process.
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.
A question worth separating out:
Q: Who should own just-in-time access decisions and revocation accountability?
A: Ownership should sit with the identity governance and PAM function, with clear operational responsibility in the systems team that grants access. If request, approval, and revocation are split across too many teams, accountability becomes unclear and the control weakens. The accountable team must be able to show who approved, who used, and who removed the access.
