TL;DR: C1.ai argues that least privilege has not kept pace with SaaS, IaaS, PaaS, and on-prem complexity because standing permissions linger after they are needed, creating risk and workflow friction. Zero standing access shifts control to just-in-time provisioning, step-up approvals, and full auditability, which better matches modern access demand.
At a glance
What this is: This is a position piece arguing that least privilege has become too static for modern identity estates and that zero standing access is the more workable control model.
Why it matters: It matters because IAM, PAM, NHI, and agent governance all fail when access is designed to persist instead of being issued and revoked around the task.

Context
Least privilege is the idea that an identity should only hold the access it needs, but the article argues that the model breaks down when privileges are granted in advance and left standing. In modern identity estates that span SaaS, IaaS, PaaS, on-prem, service accounts, NHIs, contractors, and AI agents, predicting every access need up front is no longer realistic.
The governance gap is not the principle itself but the persistence of access after the task ends. For IAM and PAM teams, that shifts the real control question from minimising a static entitlement set to eliminating standing access and governing issuance, approval, and revocation at the moment of use.
Key questions
Q: What breaks when least privilege is applied as a static model in modern environments?
A: Static least privilege breaks when identity and workload needs change faster than access reviews can keep up. The result is either over-granted access that lingers or blocked workarounds that bypass governance. In practice, the control fails because it assumes stable roles and predictable usage in environments that are constantly changing.
Q: When should organisations prioritise zero standing access over permanent entitlements?
A: Organisations should prioritise zero standing access when privileged actions are intermittent, high impact, or difficult to forecast in advance. If access is only needed for a task, a project, or an emergency workflow, keeping it permanently available increases the blast radius without adding proportional value.
Q: What are the signs that standing permissions are creating governance risk?
A: Common signs include approval bottlenecks, developers and operators creating workarounds, credentials that remain active after the job is complete, and access reviews that confirm entitlements long after they were needed. Those symptoms show the organisation is governing access as a static asset instead of a time-bound control.
Q: Why do service accounts and AI agents need different controls from human users?
A: Service accounts and AI agents authenticate and act without the predictable patterns that human identity systems expect. They can operate across runtimes, scale quickly, and carry permissions into automated workflows. That means access decisions should consider workload context, runtime behaviour, and time-bound authority rather than relying only on user-centric IAM patterns.
Technical breakdown
Why standing permissions create the real access problem
Standing permissions are entitlements that remain valid beyond the specific task or business need that justified them. In dynamic environments, they accumulate because identity state changes faster than review cycles, and the original access decision is rarely revisited at the same pace as the work itself. That makes the issue less about perfect least privilege on paper and more about the blast radius that survives after the task is done. Once access lingers, the control model assumes stability where the environment is now continuously changing.
Practical implication: Treat persistence of access as the primary design failure, not the presence of a large entitlement set alone.
How just-in-time provisioning changes the control point
Just-in-time provisioning moves privilege from a standing condition to a time-bound event. Access is issued when a task begins and revoked when the task ends, which reduces the window in which abused credentials or excess permissions can be exercised. Step-up approval adds a second control layer for higher-risk actions by requiring validation in the moment rather than broad pre-authorisation. This does not remove governance work, but it relocates it to issuance time, where access intent is clearer and easier to audit.
Practical implication: Use JIT and step-up approvals for high-risk actions instead of expanding permanent entitlements.
Why auditability matters when access becomes ephemeral
Full auditability is the record layer that makes zero standing access governable. When privilege is short-lived, the organisation needs a reliable log of who requested access, who approved it, what action was taken, and whether the access was revoked as expected. Without that evidence chain, temporary access can become temporary only in theory. Auditability also helps separate valid emergency use from privilege creep, which is critical when the same workflow may apply to humans, service accounts, or AI agents.
Practical implication: Require request, approval, action, and revocation evidence for every privileged session.

NHI Mgmt Group analysis
Least privilege fails as an operating model once access patterns become dynamic. The original idea assumes identities and resource needs can be predicted and held stable long enough for a static entitlements model to work. That assumption is increasingly false across cloud, SaaS, and hybrid estates where access needs change by project, by role, and by moment. The implication is that governance has to move from provisioning-time design to use-time control.
Zero standing access is the more defensible control objective for modern identity programmes. The article is right to re-centre the problem around standing permissions rather than theoretical minimalism. What matters is not whether an entitlement model looks small on paper, but whether unused access persists after the operational need has passed. Practitioners should measure how much privilege survives outside active use, not just how much exists at provision time.
Identity blast radius: the risk is no longer defined by what access exists, but by how long it continues to exist after need has ended. That concept captures why stale permissions are more dangerous than overdesigned policies that are never enforced in time. It also explains why JIT access, approval gates, and revocation evidence belong in the same governance conversation. The practitioner conclusion is to optimise for expiration, not permanence.
AI agents and NHIs make the standing-access model even less stable. The article’s mention of service accounts and AI agents matters because non-human identities often operate at machine speed and can outlive the assumptions built into human-centric review cycles. That does not create a new governance category so much as expose the same flaw sooner. The practitioner takeaway is that access control must match the speed of execution, not the cadence of quarterly review.
Security teams need to stop treating least privilege as the endpoint. The post reflects a broader market shift where access governance is being judged by whether it enables safe work, not by whether it preserves a legacy ideal. That makes continuous verification, temporary elevation, and strong session logging the operational markers of maturity. The field is moving toward control at the moment of use, and programmes that cannot do that will keep inheriting standing risk.
From our research library:
- 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.

What this signals
Identity blast radius: the practical measure is how far access can travel after the original business need has ended. Programmes that still optimise for durable entitlements will continue to miss the real risk, which is persistent privilege attached to tasks that are already complete.
For IAM and PAM teams, the operating question is no longer whether access can be made minimal in theory. It is whether the organisation can issue, approve, and revoke privilege fast enough to match the speed of work across humans, service accounts, and AI-driven workflows.
For practitioners
- Define zero standing access as the programme goal Set policy so privileged access is granted only for a specific task and expires when the task ends. Track where standing entitlements still exist across cloud, SaaS, on-prem, and administrative workflows.
- Move approvals to issuance time Require step-up approval for sensitive actions such as production changes, data export, and emergency admin work. Keep the approval tied to the session or task so the entitlement does not remain reusable.
- Instrument privileged sessions for full auditability Log who requested access, who approved it, what was done, and when access was removed. Use those records to prove that temporary access stayed temporary.
- Review service accounts and agent access together Check whether machine identities, service accounts, and AI agents still hold standing permissions that outlast the job they were created for. Remove persistent access paths where the workflow can safely re-authorise on demand.
Key takeaways
- The article argues that least privilege fails in practice because access models are still built around standing permissions in environments that change too quickly.
- The operational alternative is zero standing access, where privilege is issued just in time, approved in the moment, and removed when the task ends.
- Identity governance programmes should measure how much access persists after need has passed, because that persistence is where the real risk lives.

Key terms
- Standing Permission: Access that remains active after the original task or justification has ended. In identity programmes, standing permission is the condition that turns a temporary need into an ongoing exposure window, especially when review and revocation lag behind operational change.
- Zero Standing Access: Zero Standing Access means no user, workload, or agent keeps persistent elevated privileges by default. Access is granted only when required, for a specific purpose, and for a short duration. This approach reduces attack surface, limits misuse, and improves accountability in cloud, identity, and automation-heavy environments.
- Just-in-Time Provisioning: Just-in-time provisioning creates an account or entitlement at the moment it is needed, then removes it later. It reduces standing access duration, but it still relies on a static identity or role existing during the access window, which leaves room for misuse if revocation lags.
- Step-up Approval: An additional validation step required before a sensitive action can proceed. It is typically used to confirm intent, scope, or context at the moment of execution, making it suitable for privileged operations where blanket approval would create excessive standing access.
