TL;DR: Over-access, privilege creep, and toxic permission combinations turn ordinary employees, contractors, and vendors into high-impact internal risk, according to SecurEnds. The governance failure is not intent detection alone, but the loss of least privilege across joiner-mover-leaver and access review processes.
Editorial analysis by NHI Mgmt Group, based on content published by SecurEnds: “Modern Insider Threats Start with Over Access: Real Case Studies”.
Key questions
Q: What breaks when users keep access after their job changes?
A: When role changes do not trigger clean entitlement removal, old permissions stack with new ones and create privilege creep.
Q: Why do privileged accounts increase insider threat risk so much?
A: Privileged accounts expand the amount of data, systems, and actions available to one identity.
Q: What do security teams get wrong about access reviews?
A: Teams often treat access reviews as proof of control, when they are really only a point-in-time check.
Practitioner guidance
- Map effective access, not just assigned roles Build reviews around what an identity can actually do across SaaS, cloud, and DevOps systems after inherited permissions and exceptions are applied.
- Detect toxic permission combinations Add segregation-of-duties analysis to access certification so conflicting entitlements are flagged as a single risk, not separate harmless grants.
- Remove access that outlives its business need Tie temporary project access, emergency elevation, and vendor permissions to explicit expiry and revocation checkpoints in lifecycle workflows.
Bottom line: Excess access turns ordinary identities into high-impact insider-risk paths when privilege creep and toxic permission combinations are left unchecked.

Excess access is the real insider-risk control failure, not a side effect. The article is right to shift the conversation away from malicious intent and toward entitlement accumulation. When users keep permissions after role changes, temporary projects, or offboarding failures, insider-risk programmes are no longer dealing with behaviour alone but with structurally excessive reach. The practitioner conclusion is straightforward: access governance must be treated as a primary risk control, not an audit afterthought.
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 handle third-party access to reduce insider risk?
A: Third-party access should be time-bound, least-privileged, and tied to a named business owner who can revoke it when the relationship changes. Vendors and contractors often keep permissions after the original need ends, which makes them indistinguishable from internal over-access in practice.
