PAM is shifting from accounts to actions in privileged access

At a glance

What this is: The article argues that privileged access is moving from account-centric control to action-centric governance as non-human identities and AI agents dominate privileged activity.

Why it matters: This matters because IAM, PAM, and IGA teams now have to govern ephemeral privilege at the moment of action across human and non-human identities, not just manage standing accounts.

By the numbers:

• 91% of former employee tokens remain active after offboarding, leaving organisations vulnerable to potential security breaches.

Context

Privileged access is no longer limited to a small set of administrator accounts. In practice, service accounts, cloud workloads, automation pipelines, and AI agents are generating a much larger share of privileged actions than traditional human admins, which breaks the old assumption that PAM can focus on vaulted credentials and a stable list of privileged users.

For IAM and PAM teams, the key question is whether access is governed at the moment an action is taken. A model built around passwords, long-lived entitlements, and periodic review struggles when privilege is temporary, policy-driven, and spread across human, machine, and agentic actors. That is the governance gap this article is really pointing to.

The article is typical of current PAM market analysis in one important sense: it treats privileged access as a fabric, not a standalone tool. That is the right direction, but it also means identity governance has to be more dynamic than traditional vault-and-session-monitoring programmes.

Key questions

Q: How should security teams govern non-human identities that have persistent access?

A: Security teams should treat every non-human identity as a managed asset with an owner, an explicit purpose, a scoped privilege set, and a defined offboarding path. Persistent access should be replaced with time-bound or task-bound access wherever possible, and every credential should be traceable to the system or workflow it supports.

Q: Why do non-human identities change the PAM risk model?

A: Non-human identities change the PAM risk model because they authenticate continuously, operate at machine speed, and often lack stable human ownership. Those traits make account-centric reviews incomplete. The real risk is not just a credential existing, but an overpowered identity repeatedly acting beyond the scope its original access decision assumed.

Q: What breaks when organisations rely on password vaults for every privileged identity?

A: Password vaults still help, but they break down when the real risk is persistent authorisation rather than secret storage. If an identity can access a system through certificates, tokens, APIs, or agentic workflows, the vault does not fully govern what that identity can do at execution time. That leaves the privileged action itself under-controlled.

Q: Who is accountable when AI or machine identities are over-privileged?

A: Accountability sits with the teams that provisioned, approved, and operated the identity, but governance ownership must be explicit. If a machine identity or AI system can act beyond its intended scope, the organisation needs a named control owner, a revocation path, and evidence that access was reviewed against actual use.

Technical breakdown

Privilege is now an action, not an account

Traditional PAM was built to identify privileged accounts, store their credentials, and monitor sessions. That model works when privilege is stable and attached to a small number of named users. The article reflects a different reality: an identity can now become privileged only at the moment it performs a sensitive action. That changes the control problem from credential custody to entitlement resolution, policy evaluation, and continuous revalidation at runtime. In practice, privilege is increasingly an event, not a property.

Practical implication: PAM programmes need policy-driven access decisions at the point of use, not just stronger vaulting around standing accounts.

Why NHI and AI agent privilege changes the PAM model

Non-human identities and AI agents often run unattended, at machine speed, and across many systems. The article’s point is that authentication alone does not explain their risk, because once they are trusted, they may execute privileged actions without human supervision. For NHI governance, the important issue is not just who authenticated, but what the identity can do, how long that privilege persists, and whether the identity can be constrained to the task it was assigned. Short-lived credentials and just-in-time access matter because they reduce the window in which unattended privilege can be abused.

Practical implication: classify high-value service accounts, workflows, and AI agents as privileged actors that require task-scoped access and expiry controls.

Zero standing privilege is becoming the operating model

Zero standing privilege, or ZSP, removes persistent access and replaces it with on-demand permission. The article ties this to ephemeral certificates, policy-based entitlement control, and integration with identity sources so privilege is continuously refreshed rather than held indefinitely. That is materially different from password rotation, because rotation still assumes a standing secret exists. ZSP changes the baseline from owning credentials to issuing access only when there is a current need, with auditability preserved after the privilege window closes.

Practical implication: reduce reliance on long-lived secrets and move the highest-risk admin paths toward on-demand, time-bounded access.

Threat narrative

Attacker objective: The objective is to turn a broadly trusted identity into a durable path for privileged system change, lateral access, or control-plane abuse.

1. Entry occurs when a non-human identity, automation pipeline, or AI agent receives broad privileged access that is valid beyond a single task window.
2. Escalation follows when that identity can perform sensitive actions without just-in-time constraints, allowing privileged use to spread across systems and identities.
3. Impact occurs when static credentials, broad entitlements, or unmanaged certificates let privileged activity persist without tight task scoping or revocation.

NHI Mgmt Group analysis

Privilege is being redefined around action, and that changes the control boundary. When privilege is attached to the action instead of the account, vault-first PAM becomes only one layer of control, not the core model. The article accurately reflects a market shift toward runtime entitlement decisions, which is where modern IAM and PAM governance now has to live. The practical conclusion is that policy evaluation must sit closer to execution than credential storage does.

Non-human identities are now the dominant privileged actors, so human-era PAM assumptions no longer hold. Service accounts, automation pipelines, and AI agents generate privileged activity without the behavioral signals that human access reviews rely on. That makes the old assumption of a visible, reviewable, and stable operator increasingly fragile. The practical conclusion is that NHI governance has to evaluate task scope, expiry, and blast radius instead of asking only whether an account is approved.

Zero standing privilege is the most important conceptual shift here because standing access is the problem, not just the secret. Short-lived certificates and just-in-time access reduce exposure, but the bigger change is that the identity no longer owns persistent privilege. That shifts accountability from credential possession to authorization at the moment of use. The practical conclusion is that privileged access should be issued only for the current task and revoked by design, not by cleanup.

Quantum-safe PAM is becoming a governance issue, not a future optimization. The article’s mention of harvest-now-decrypt-later risk shows that privileged connectivity is part of long-lived cryptographic exposure, not just access management. That matters most in regulated, sovereignty-sensitive environments where privileged sessions are persistent and highly targeted. The practical conclusion is that cryptographic choices for privileged channels now belong in the same risk discussion as access policy and identity lifecycle.

Identity security is converging into one fabric, and PAM can no longer sit apart from IGA, IAM, and secrets management. That convergence is useful only if governance logic is consistent across human users, service identities, and machine workloads. Otherwise, organisations simply relocate the same privilege problem into another control plane. The practical conclusion is to treat privileged access as a shared policy layer across identity domains, not as a standalone vault administration function.

From our research:

• 91% of former employee tokens remain active after offboarding, leaving organisations vulnerable to potential security breaches, according to The 2025 State of NHIs and Secrets in Cybersecurity.
• 62% of all secrets are duplicated and stored in multiple locations, causing unnecessary redundancy and increasing the risk of accidental exposure, according to The 2025 State of NHIs and Secrets in Cybersecurity.
• For a broader breach lens, see 52 NHI Breaches Analysis, which maps the recurring failure modes behind exposed tokens, overused identities, and weak offboarding.

What this signals

Identity blast radius: as privileged activity shifts from users to workloads and agents, the primary question becomes how far a single identity can move before governance notices. That requires tighter policy boundaries, shorter access windows, and stronger coupling between identity state and system action. The organisations that still think in terms of account lists will keep missing the real control surface.

With 88.5% of organisations saying their non-human IAM practices lag behind or merely match human IAM, per The 2024 Non-Human Identity Security Report, PAM modernisation is no longer optional governance refinement. It is the mechanism that determines whether privileged action is governed in real time or merely documented after the fact.

Teams should expect privileged access, secrets management, and workload identity to keep converging into one operational discipline. The practical programme response is to build shared policy, shared inventory, and shared evidence across all identity types, then use the NIST AI Risk Management Framework only where autonomous behaviour is genuinely in scope.

For practitioners

• Map privilege by action, not by account Inventory the systems and workflows where identities can make security-relevant changes, then classify those actions as privileged even when the actor is a service account or AI agent. Use the same lens across admin consoles, APIs, pipelines, and automation paths so that governance reflects actual impact rather than account labels.
• Replace standing access with task-scoped access paths Prioritise the most sensitive non-human and administrator flows for just-in-time access, ephemeral credentials, and expiry by default. Keep the scope narrow, tie issuance to an explicit purpose, and make revocation automatic when the task ends or policy changes.
• Unify PAM, IGA, and secrets governance Create one policy model for credential issuance, entitlement approval, and audit evidence so that human and non-human identities are governed consistently. The goal is to avoid separate exceptions for vaults, workload identities, and agent-driven automation.
• Treat AI agents as privileged identities until proven otherwise If an AI agent can choose tools, access data, or trigger actions, place it under privileged access controls with explicit scope and review points. Do not allow agent behaviour to inherit trust simply because it sits inside an approved workflow.
• Plan a controlled migration away from password vault dependence Retain vaulting where needed, but build a staged path to certificate-based, zero-standing-privilege access for the highest-risk pathways. Focus first on SSH key governance, machine-to-machine access, and other long-lived credentials that create persistent exposure.

Key takeaways

• Privileged access is moving from account ownership to action governance, which makes static PAM models insufficient on their own.
• Non-human identities and AI agents now account for a large share of privileged activity, so runtime controls matter more than credential custody.
• The practical direction is clear: reduce standing privilege, unify identity governance, and issue access only when a specific task requires it.

Key terms

• Privileged Action: A privileged action is a sensitive operation that can change data, configuration, access, or control inside an environment. In modern PAM, the action matters more than the account label because the same identity may be harmless in one context and high risk in another.
• Zero Standing Privilege: A control model in which an identity does not keep persistent access unless it is actively needed. For NHIs, this means credentials and permissions are issued for a narrow task and then removed. It reduces the time window and reuse value of stolen access.
• Ephemeral Credentials: Ephemeral credentials are short-lived access artefacts issued for a limited task or session. They reduce the window for abuse, but they only improve security when paired with strong scope limits, telemetry, and automatic revocation at task completion.
• Non-Human Identity (NHI): A digital identity assigned to a non-human entity such as a software application, service account, API key, bot, machine, or AI agent that enables it to authenticate and interact with systems without direct human involvement. NHIs now outnumber human identities in most enterprises by 25 to 50 times.
