TL;DR: Zero trust and least privilege are often discussed together, but they solve different identity problems: one continuously verifies access, while the other constrains standing permission, according to Zluri. The distinction matters because teams that blur verification with authorization tend to overestimate how much risk their IAM controls actually remove.
Editorial analysis by NHI Mgmt Group, based on content published by Zluri: “Zero Trust vs Least Privilege: 5 Key Differences”.
Key questions
Q: Why do NHIs complicate zero trust and least privilege efforts?
A: NHIs complicate zero trust because they are numerous, persistent, and often tightly integrated into applications and pipelines.
Q: Why does least privilege matter so much in Zero Trust and cloud security programmes?
A: Least privilege matters because it limits what any account, workload, or service can do if it is misused or compromised.
Q: What breaks when teams treat zero trust as a substitute for access scoping?
A: They end up verifying too much and constraining too little.
Practitioner guidance
- Separate verification from authorization in policy design Write distinct controls for continuous trust evaluation and for entitlement minimisation so audits can test each one on its own merits.
- Inventory standing access before tightening zero trust rules Review which human and non-human identities hold persistent permissions that exceed their operational need, then reduce scope before layering on more context checks.
- Measure entitlement scope and trust checks separately Track privilege breadth, dormant access, and session verification outcomes as different metrics instead of using one to imply the other.
Bottom line: Zero trust and least privilege address different identity failures, so using one term for both hides gaps in design and governance.

Zero trust and least privilege should be treated as separate governance layers, not interchangeable slogans. Zero trust governs whether an access attempt should be trusted right now, while least privilege governs how much access an identity should hold at all. When teams collapse the two, policy language becomes vague and control testing loses precision. The result is a programme that looks comprehensive on paper but leaves one of the two failure modes untouched.
A few things that frame the scale:
- Systems with least-privileged AI access had a 17% incident rate vs 76% for over-privileged systems. Organisations failing to scope AI access properly are 4.5x more likely to experience a security incident, according to the 2026 Infrastructure Identity Survey.
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: How do IAM teams know whether an authorization platform is working?
A: Look for measurable reduction in policy exceptions, faster access changes, and complete decision logging across the highest-risk applications. If teams still need code changes for routine access updates, the control is not externalized enough. A working platform should improve auditability without adding noticeable latency to legitimate requests.
