Least privilege for NHIs now depends on visibility and JIT

At a glance

What this is: This is an analysis of practical least-privilege steps for human and non-human identities, with the key finding that visibility, context, and JIT access are the controls that turn theory into governance.

Why it matters: It matters because IAM, IGA, PAM, and NHI programmes all fail in the same place when standing privilege persists across humans, workloads, and AI agents.

By the numbers:

• 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools.
• Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
• 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface.
• 71% of NHIs are not rotated within recommended time frames, increasing the risk of compromise over time.

Context

Least privilege means giving each identity only the access it needs to complete a task, and nothing more. In practice, that is difficult when organisations must govern humans, service accounts, API keys, workload identities, and AI agents across hybrid and multi-cloud environments.

The governance problem is not the principle itself. The problem is operational scale: identity sprawl, static permissions, manual reviews, and stale elevated access make least privilege easy to describe and hard to enforce. SailPoint frames the issue around three practical steps, but the underlying challenge is broader than any single product workflow.

For IAM, IGA, and PAM teams, the article is a reminder that privilege management must extend beyond employee access reviews. When non-human and autonomous access sit outside the identity programme, the organisation is only governing part of its attack surface.

Key questions

Q: How should security teams implement just-in-time access for privileged identities?

A: Start with the highest-risk roles, such as domain administrators, production operators, and service accounts with broad write access. Use an approval workflow that issues access for a defined task window, logs every action, and revokes the privilege automatically when the task finishes. The control only works if revocation is enforced without manual follow-up.

Q: Why does standing privilege increase risk across humans and non-human identities?

A: Standing privilege keeps elevated access available when it is no longer needed, which expands the window for misuse, theft, and accidental overreach. The risk applies to both people and NHI because attackers target whichever identity has the broadest permissions and the weakest lifecycle discipline. Persistent access is an exposure problem before it is a usability benefit.

Q: What do security teams get wrong about least privilege in cloud environments?

A: They often treat least privilege as a one-time entitlement exercise instead of a lifecycle problem. In cloud environments, permissions drift, new integrations appear, and identities accumulate access faster than review cycles can keep up. Without discovery, ownership, and revocation, least privilege becomes a policy statement with no operational backing.

Q: How do IAM and PAM teams decide whether JIT access is needed?

A: Use JIT when the role is powerful, the task is short, and persistent elevation cannot be justified by business need. If the identity only requires elevated access occasionally, permanent privilege is usually the wrong default. The decision should be based on task duration, blast radius, and the quality of your audit trail.

Technical breakdown

Why standing privilege defeats least privilege at scale

Standing privilege is persistent elevated access that remains available long after the original task is complete. It becomes a governance failure when access is granted by default and removed only by exception, because the longer the privilege persists, the larger the blast radius becomes if credentials are stolen or misused. In cloud and hybrid environments, privileged roles often accumulate through convenience, not need, which makes least privilege a policy statement rather than an operational state.

Practical implication: identify privileged accounts that remain continuously enabled and move them into time-bound approval and revocation workflows.

How NHI visibility changes identity governance

NHI visibility means discovering service accounts, machine identities, APIs, and AI agents, then attaching ownership, purpose, and entitlement context to each one. Without that inventory, IGA and PAM controls only cover the identities already known to the programme, leaving a large unmanaged layer in place. Visibility is not just counting accounts. It is the prerequisite for deciding which identities need rotation, review, offboarding, or tighter policy enforcement.

Practical implication: build an authoritative inventory of non-human identities and map each one to an owner, function, and access boundary.

Why JIT access is the practical answer to temporary privilege

Just-in-time access replaces permanent elevated permissions with short-lived access granted only when a task requires it. The technical value is not only shorter duration. It also creates a narrower audit window, reduces standing exposure, and forces privileged actions into an approval and logging path that can be reviewed later. For machine and human administrators alike, JIT works best when the request, approval, session, and revocation steps are linked into one governed workflow.

Practical implication: reserve JIT for high-risk roles first, then expand it to workloads and service accounts where persistent privilege is not defensible.

NHI Mgmt Group analysis

Least privilege has become an identity governance problem, not a policy slogan. The article is right to treat standing privilege as the main failure mode, because the risk is created when permissions outlive the task they were meant to support. In modern environments, that applies equally to humans, workloads, and AI-adjacent automation. The practitioner takeaway is simple: if privilege is not time-scoped and ownership-backed, it is not least privilege in operational terms.

Visibility is the named concept that separates governance from guesswork. You cannot right-size access for identities that have not been discovered, classified, and assigned to an owner. That is especially true for non-human identities, where service accounts and API keys are often created faster than they are reviewed. The implication is that identity programmes must treat discovery as a control, not a reporting exercise.

Standing privilege is the control debt that keeps producing avoidable exposure. Persistent elevation is convenient for admins and developers, but it assumes access will be reviewed before it is abused. That assumption fails whenever credentials are stolen, shared, or simply forgotten. For practitioners, the real governance question is whether permanent elevation is still justified in any tier of access.

AI-driven access context changes the quality of governance decisions, but it does not remove governance responsibility. Context such as usage patterns, high-risk permissions, and anomalous behaviour can help access owners make better decisions than spreadsheet reviews alone. Yet the decision remains a governance act, not an automated verdict. The implication for IAM and IGA teams is to use context to improve judgment, not to outsource accountability.

Just-in-time access is becoming the minimum viable control for high-risk privilege. The article shows why permanent privileged access is no longer defensible for many administrative use cases. When task duration is short and auditability matters, ephemeral elevation reduces exposure without forcing a full redesign of the environment. Practitioners should treat JIT as a boundary-setting mechanism across both human and non-human privileged workflows.

From our research:

• 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to Ultimate Guide to NHIs.
• Only 5.7% of organisations have full visibility into their service accounts, which shows how far most programmes still are from complete NHI governance.
• Forward pivot: For a deeper view of lifecycle control, see Ultimate Guide to NHIs , Lifecycle Processes for Managing NHIs for provisioning, rotation, and offboarding discipline.

What this signals

Standing privilege is now the simplest way to describe the identity risk many programmes still tolerate. The governance gap is not just access volume, it is the persistence of access that no longer has a business justification. When you can discover identities but cannot reliably remove elevation, the programme is only partway mature.

Identity teams should expect pressure to prove access reduction, not just access review completion. Boards and auditors are increasingly looking for evidence that privileged access is time-bound, owned, and reversible. That shifts the conversation from certification cadence to lifecycle enforcement, especially for service accounts and workload credentials.

With 68% of organisations saying they do not know how to fully address NHI risks, the next phase of maturity is likely to be less about more tooling and more about tighter lifecycle control across humans, workloads, and AI-enabled access paths.

For practitioners

• Inventory all privileged identities across the environment Discover humans, service accounts, machine identities, APIs, and AI agents in one governed inventory, then assign a real owner and business purpose to each identity so no privileged account remains anonymous.
• Convert persistent elevation into time-bound access Move high-risk administrative roles into just-in-time workflows that grant access only for the task window, then automatically revoke it when the session ends.
• Use context to right-size entitlements Enrich access reviews with usage data, privilege sensitivity, and anomaly signals so reviewers can remove permissions that are never used or are clearly out of scope.
• Log every privileged session end to end Capture request, approval, provisioning, use, and revocation events for privileged access so audits can reconstruct who had access, when it was active, and why it was granted.
• Prioritise NHI offboarding and rotation where access persists Start with service accounts, API keys, and workload credentials that have no clear expiration path, because stale non-human access is where standing privilege becomes hardest to defend.

Key takeaways

• Least privilege fails when elevated access becomes permanent rather than task-scoped.
• Visibility into non-human identities is a prerequisite for governing privilege at scale.
• JIT access is the most practical way to reduce standing privilege without blocking legitimate work.

Key terms

• Standing Privilege: Standing privilege is elevated access that remains active beyond the immediate task or approval that justified it. It creates a persistent exposure window, especially when identities are shared, forgotten, or overused. In identity programmes, it is the opposite of task-scoped access and a common cause of avoidable blast radius.
• Just-in-Time Access: Just-in-time access is a pattern that grants elevated permissions only for a defined task window and then removes them automatically. It reduces persistent exposure and improves auditability. For non-human and human privileged identities, the value comes from short duration, enforced revocation, and logged execution.
• Non-Human Identity: A non-human identity is a machine or software identity such as a service account, API key, token, certificate, or workload credential. These identities often run unattended, accumulate broad permissions, and are difficult to review manually, which makes lifecycle governance and ownership essential.
• Identity Governance and Administration: Identity Governance and Administration is the discipline of defining, reviewing, and enforcing who or what has access to systems and data. It includes access reviews, ownership, certification, and deprovisioning. For non-human identities, the same governance model must be adapted to machine speed and machine scale.
