TL;DR: The principle of least privilege reduces unauthorized access, privilege creep, and malware blast radius by limiting human and non-human permissions to what each task requires, with stronger auditability and revocation discipline, according to Zluri. That model remains useful, but in modern SaaS and NHI environments it fails whenever access is granted faster than it is reviewed or removed.
NHIMG editorial — based on content published by Zluri: Access Management What Is The Principle Of Least Privilege (PoLP)?
By the numbers:
- Only 5.7% of organisations have full visibility into their service accounts.
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface.
- 79% of organisations have experienced secrets leaks, with 77% of these incidents resulting in tangible damage.
Questions worth separating out
Q: What breaks when least privilege is only enforced at provisioning time?
A: The control breaks when access outlives the task that justified it.
Q: Why do service accounts with standing privilege increase breach impact?
A: Standing privilege gives an attacker or misconfigured workflow persistent capability after the original business need has passed.
Q: How do security teams know whether least privilege is actually working?
A: They measure whether unnecessary access is being removed quickly and consistently, not just whether least-privilege policy exists on paper.
Practitioner guidance
- Map effective privilege across applications and integrations Inventory role-based access, app scopes, and API permissions together so you can see the real access boundary rather than the one shown in a single admin console.
- Replace standing elevation with time-bound access Use just-in-time access for tasks that need escalation, and confirm that the elevated entitlement expires automatically after the task completes.
- Extend access reviews to non-human identities Put service accounts, API keys, and tokens into the same review cycle as human accounts, then require revoke, rotate, or justify outcomes for every exception.

PoLP is still the right objective, but modern identity estates have made it harder to prove than to claim. The guide correctly treats least privilege as a balance between access and productivity, yet the operational challenge is that SaaS entitlements, service accounts, and tokens now span too many systems to inspect manually. That means the discipline fails first as a visibility problem and only later as a permission problem. Practitioners should treat privilege scope as a continuously testable condition, not a policy statement.
A few things that frame the scale:
- 91.6% of secrets remain valid five days after the targeted organisation is notified, showing a critical gap in remediation procedures, according to Ultimate Guide to NHIs.
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
A question worth separating out:
Q: Who should own least privilege governance across humans and non-human identities?
A: IAM, PAM, and application owners should share responsibility, because least privilege fails when ownership is split between provisioning, approval, and revocation. Human users, service accounts, and tokens all need accountable owners and an enforced offboarding path. Without clear ownership, excess access becomes nobody’s problem until an incident exposes it.
