Third-party access management: where the governance gap starts

TL;DR: Third-party access management is increasingly exposed by manual approvals, weak revocation, inconsistent controls, and limited visibility, according to Zluri’s analysis. For identity teams, the issue is not just external access volume but whether lifecycle, monitoring, and least-privilege controls actually hold once access leaves the core workforce boundary.

Questions worth separating out

Q: How should security teams govern third-party access in practice?

A: Security teams should govern third-party access as a lifecycle process, not a one-time approval.

Q: When does third-party access become a higher risk than it appears?

A: Third-party access becomes high risk when it is broad, difficult to monitor, or hard to revoke.

Q: What do organisations get wrong about third-party access reviews?

A: Many organisations review whether access was approved, but fail to verify whether it is still needed, still scoped correctly, or still tied to an active contract.

Practitioner guidance

• Define third-party access as a lifecycle-controlled identity class Create a separate approval, expiry, and ownership model for vendors, contractors, and partners so their entitlements are tracked from request through revocation.
• Automate expiry and deprovisioning for all external access Link every third-party grant to a time limit, a named business owner, and an automated removal workflow so access cannot outlive the task.
• Tighten segmentation around third-party task paths Limit external users to the smallest application, dataset, or environment slice needed for the engagement and prevent lateral movement into adjacent systems.
