TL;DR: Vendor access management reduces the friction of onboarding, JIT access, and revocation for third parties, but the operational gap remains the same: access must be granted, scoped, and removed cleanly across systems, according to StrongDM. The real issue is not access speed, but whether governance can keep vendor privileges bounded across the full lifecycle.
Editorial analysis by NHI Mgmt Group, based on content published by StrongDM: “Vendor Access Management (VAM) Explained”.
Key questions
Q: What breaks when vendor access is not fully revoked across all systems?
A: Least privilege breaks when access is removed from the request system but remains active in one or more downstream platforms.
Q: Why does JIT access still leave risk in vendor access management?
A: JIT access reduces standing exposure, but it does not eliminate the risk created by fragmented revocation.
Q: How can teams tell whether access governance is actually working?
A: Look for short revocation times, low rates of stale entitlements, and repeatable access review outcomes across systems.
Practitioner guidance
- Map vendor access to every downstream permission store Document where vendor access is actually enforced, including IdP mappings, application roles, cloud entitlements, and local administrative paths.
- Make offboarding a revocation verification exercise Require evidence that access was removed from each system, not just that a ticket was closed or a request was denied.
- Separate federation from entitlement review Review vendor authentication trust separately from the roles, scopes, and resource-level permissions the vendor can reach after login.
Bottom line: Vendor access management only works when onboarding and offboarding are treated as one lifecycle, not two separate processes.

Vendor access management is really an offboarding problem disguised as onboarding convenience. The article describes faster provisioning and controlled access, but the governance failure is that access must be removed everywhere it exists, not only where it was first approved. Lifecycle closure is what makes least privilege real, and any programme that cannot prove removal is only managing temporary exposure. Practitioners should measure vendor access by revocation completeness, not onboarding speed.
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: How should organisations govern vendor access as part of identity management?
A: Treat vendor access as a lifecycle-controlled identity, not as a loose operational convenience. Every external account, token, or delegated permission should have an owner, a purpose, an expiry condition, and a documented revocation path. That approach keeps procurement, security, and IAM aligned and makes offboarding enforceable instead of optional.
