Identity and access management tools now must govern NHIs

At a glance

What this is: This is Apono's roundup of IAM tooling, with the key finding that modern IAM now has to govern humans and NHIs together as cloud estates, secrets, and AI agents expand the access surface.

Why it matters: It matters because IAM teams can no longer treat privileged access, secrets, and access governance as separate silos when the same control plane must cover people, pipelines, and machine identities.

By the numbers:

• 78% of organizations plan to ramp up spending on identity and access management tools to ease concerns over identity-based attacks that lead to phishing and lateral movement.

Context

Identity and access management tools are no longer just about logging humans in. In cloud-native environments, the harder problem is controlling who or what can act across infrastructure, SaaS, CI/CD, and data systems when service accounts, API tokens, certificates, and AI-powered agents all need access.

That shifts IAM from a sign-in function to a governance layer for least privilege, privileged access, and secrets exposure. For practitioners, the question is not whether to centralize identity controls, but how to make those controls work across human identities and non-human identities without creating standing access that outlives its purpose.

Key questions

Q: How should security teams govern non-human identities in cloud environments?

A: Security teams should govern non-human identities through the same lifecycle discipline they apply to people, but with controls designed for machine speed and scale. That means discovery, ownership, least privilege, rotation, revocation, and auditability across service accounts, tokens, certificates, and CI/CD identities. The key is to remove standing access and make every credential both traceable and revocable.

Q: Why do service accounts and API keys create more risk than human accounts in practice?

A: Service accounts and API keys often create more risk because they are reused across systems, embedded in code or pipelines, and left active long after the original use case changes. Unlike human accounts, they are easy to forget and hard to review manually. When privileges are broad and long-lived, they become durable pathways for lateral movement and data access.

Q: What breaks when JIT access is layered on top of poor entitlement hygiene?

A: JIT access breaks down when the underlying entitlements are already excessive, unclear, or poorly owned. In that case, time-bounding a request does not fix the fact that the role itself is too broad or the approval path lacks context. The result is faster access to the wrong permissions, which preserves risk while adding friction.

Q: How do teams know if their IAM programme is actually reducing identity risk?

A: Teams know IAM is reducing risk when they can show fewer standing privileges, shorter access duration, faster revocation, and fewer credentials stored in code or shared systems. The strongest indicator is not more approvals, but less permanent access and cleaner ownership across human and non-human identities. If privileges still outlive the work, the programme is not yet effective.

Technical breakdown

Why modern IAM is a control plane, not just authentication

Classic IAM answered two questions: who are you and what may you do. In cloud and SaaS environments, that scope expands into policy enforcement across cloud accounts, APIs, infrastructure, and developer workflows. Authentication proves identity, but authorization determines blast radius, and the latter is where over-permissioning hides. Centralized IAM reduces drift only if it can express policy across heterogeneous systems, not merely federate login. Practical implication: treat authentication as the front door and authorization as the real control surface.

Practical implication: map authorization decisions to the systems that actually consume them, not just to the identity provider.

JIT access and privileged access management reduce standing privilege

Just-in-Time access and PAM are now tightly linked because standing privilege is the easiest path from credential compromise to lateral movement. JIT changes access from persistent entitlement to time-bound authorization, usually with policy checks, approval context, and automatic expiry. That does not remove the need for logging or segmentation, but it narrows the window in which privileged credentials can be abused. In cloud-native estates, the goal is not merely faster access, but access that disappears after the task is complete. Practical implication: replace permanent elevated roles with task-scoped elevation wherever the workflow allows it.

Practical implication: use time-bound elevation for administrative and break-glass workflows instead of leaving privileged roles permanently assigned.

NHI governance depends on secrets, visibility, and lifecycle control

Service accounts, API keys, tokens, and certificates all behave as non-human identities, and they accumulate risk when they are embedded in code, CI/CD, or application configs. The governance problem is lifecycle, not inventory alone. If you cannot discover where secrets live, prove who can use them, rotate them on schedule, and revoke them at offboarding, then the identity layer becomes durable attack infrastructure. That is why NHI security now sits alongside PAM and access governance. Practical implication: connect discovery, rotation, and revocation into one operational process, not three disconnected tools.

Practical implication: build one workflow that discovers, right-sizes, rotates, and offboards non-human identities.

NHI Mgmt Group analysis

Identity sprawl is now an access governance problem, not an inventory problem. As cloud estates grow, the number of subjects asking for access expands from people to pipelines, tokens, workloads, and AI-powered agents. That changes the job of IAM tools from authenticating users to governing distributed privilege across heterogeneous execution contexts. Practitioners should stop treating identity as a directory issue and start treating it as a runtime control plane problem.

Standing privilege remains the fastest route from legitimate access to lateral movement. The article's repeated emphasis on JIT, PAM, and least privilege reflects a real structural shift: persistent entitlements are too easy to inherit, reuse, and abuse. Once access is static, remediation becomes reactive and the attack window stays open. The practitioner takeaway is that privilege scope must be continuously constrained, not periodically cleaned up.

NHI governance is the named concept modern IAM stacks keep colliding with. Service accounts, API tokens, certificates, and AI agents all create durable machine-access paths that often sit outside human-centric governance processes. That is why access reviews, lifecycle control, and entitlement governance need to include non-human identities by default. Teams that still separate human IAM from machine access are managing the same risk in two different queues.

Time-bound access only works when the programme can express purpose, duration, and revocation together. JIT access is not just a convenience layer for engineers. It is a governance pattern that assumes the request, approval, and expiry logic are aligned to actual operational tasks. If those controls are fragmented, JIT becomes theatre rather than containment. Practitioners should evaluate whether their access model can actually expire privilege when the work ends.

Modern IAM buying decisions are converging on governance depth, not feature count. The market is moving toward tools that can prove least privilege across cloud, SaaS, and machine identity layers instead of isolated point solutions. That does not make consolidation the answer by itself, but it does mean platform fit now depends on lifecycle coverage, secret visibility, and operational friction. Buyers should test how far a tool reaches into the identity blast radius, not just how many sign-in methods it supports.

From our research:

• 64% of valid secrets leaked in 2022 are still valid and exploitable today, proving that detection alone is not enough without automated revocation, according to The State of Secrets Sprawl 2026.
• Our research also found that 92% of organisations expose NHIs to third parties, which turns partner access into a persistent governance problem rather than a one-time trust decision.
• For a broader governance baseline, see Ultimate Guide to NHIs for lifecycle, visibility, rotation, and offboarding practices that apply across machine identities.

What this signals

The operational signal for IAM teams is clear: programmes built around periodic review cycles will keep missing machine identities that are granted, used, and forgotten between recertification windows. Standing privilege debt: the longer a credential remains valid, the more likely it is to become a hidden dependency in pipelines, scripts, and partner integrations.

Apono's framing reinforces a broader market shift toward controls that can compress access duration across cloud, SaaS, and machine workflows. That means identity teams should measure not just how many entitlements exist, but how many can be created and revoked automatically without manual queueing or spreadsheet governance.

The strongest preparation step is to align NHI governance with lifecycle controls, then anchor that work to established guidance such as Ultimate Guide to NHIs and the NIST AI Risk Management Framework where autonomous or AI-adjacent workflows are in scope.

For practitioners

• Map every privileged identity class Inventory human admins, service accounts, CI/CD runners, API tokens, certificates, and AI-powered agents in one access catalogue so governance does not stop at employee accounts.
• Replace standing elevation with task-scoped access Use JIT for administration, break-glass, and high-risk SaaS access so elevated permissions exist only for the task and expire automatically when the task closes.
• Tie secrets discovery to revocation workflows Do not stop at finding exposed keys in code, config, or CI/CD. Make revocation and rotation part of the same workflow so exposure does not outlive detection.
• Unify access review across human and machine identities Extend recertification and entitlement reviews to service accounts and application credentials, then verify that every review ends with a revocable owner and a lifecycle date.

Key takeaways

• Modern IAM tools are increasingly judged by whether they can govern NHIs, not just authenticate people.
• Standing privilege, embedded secrets, and fragmented lifecycle processes are the core risks this market has to address.
• Practitioners should prioritise task-scoped access, unified entitlement governance, and automated revocation before cloud sprawl widens the blast radius.

Key terms

• Non-Human Identity: A non-human identity is any machine- or workload-based credential used to access systems, data, or services. It includes service accounts, API keys, tokens, certificates, bots, workloads, and AI agents. The governance challenge is that these identities often operate at scale, persist silently, and outlive the people or projects that created them.
• Just-In-Time Access: Just-in-time access grants privileged permissions only when a task requires them and removes them when the task ends. In practice, it shortens the window in which an identity can be abused and reduces standing privilege across cloud, SaaS, and infrastructure systems.
• Standing Privilege: Standing privilege is persistent access that remains available whether or not it is actively needed. For IAM and NHI programmes, it creates unnecessary exposure because credentials, roles, and entitlements continue to exist long after the immediate business need has passed.
