TL;DR: Agentic AI breaks the assumption that privileged access can be provisioned once and safely reused, because agents read untrusted content, act at runtime, and can carry credentials into compromised workflows, according to Britive. Zero standing privilege changes the model by making access task-scoped, expiring it after use, and removing the reusable credential from the agent session.
At a glance
What this is: This article explains why standing privileged access is a poor fit for AI agents and why zero standing privilege changes the control model.
Why it matters: IAM and PAM teams need to rethink how credentials are issued, held, and revoked when software selects actions at runtime and can be manipulated by untrusted content.
Context
Zero standing privilege is a control model for identities that only need access for a specific task at a specific moment. The problem emerges when agentic AI is treated like a deterministic service account even though it reads untrusted content, adapts at runtime, and may act on prompts or text an attacker can influence.
Britive's article frames the governance gap clearly: standing access gives an agent a reusable credential surface that can outlive the task it was meant to support. For IAM, PAM, and NHI programmes, the question is not whether agents need access, but whether any access can be justified as persistent once the system is making decisions in motion.
Key questions
Q: What breaks when AI agents are given standing privileges?
A: Auditability, containment, and accountability all degrade. A persistent agent can accumulate access beyond the task at hand, making it harder to prove why the access existed, who approved it, and when it should have ended. That creates the same governance drift seen in long-lived service accounts.
Q: Why do standing credentials create more risk for AI-connected systems?
A: Standing credentials let an identity keep operating after the original trust decision has aged out. In AI-connected systems, that is dangerous because continuous execution can turn one valid credential into repeated access across tools, data, and infrastructure. The longer privilege persists, the larger the blast radius when something goes wrong.
Q: How do teams know whether zero standing privilege is actually working?
A: Teams should look for evidence that privileged access is time-bound, fully revoked, and impossible to reuse outside the approved session. If old secrets remain valid, break-glass accounts stay active, or administrators can operate without a fresh grant, ZSP is only partially implemented.
Q: What is the difference between centralised secrets management and zero standing privilege?
A: Centralised secrets management changes where credentials are stored and who can retrieve them. Zero standing privilege changes when access exists, limiting it to the exact action window and revoking it before the next step begins. One governs storage; the other governs exposure time.
Technical breakdown
Why standing privilege fails in agentic workflows
Standing privilege means a credential exists before the action and remains available after the task is finished. That model assumes the identity's behaviour is predictable enough to provision once and review later. Agentic AI breaks that assumption because the system chooses tools, reads external content, and adapts during execution. If untrusted text can influence the agent while a credential is in memory, the attacker is effectively steering a live privileged session.
Practical implication: treat any reusable agent credential as a live attack surface, not a harmless convenience.
Secrets managers centralise storage, not privilege
A secrets manager reduces scattered credential exposure by centralising retrieval, logging access, and supporting rotation. But central storage is not the same as zero standing privilege. If an agent fetches a secret at session start and keeps it in memory, the privilege is still standing for the life of that session. The governance value comes from registration and visibility, because those controls create an inventory of which agents exist and what they can reach.
Practical implication: do not equate centralised secret storage with ephemeral access controls for agents.
Gateways and minting backends are the runtime control plane
A gateway changes the trust boundary by keeping credentials out of the agent itself. It holds the secret, checks policy, and can inject a short-lived token for approved calls. When that gateway is paired with a minting backend, the system can issue a fresh credential for each action and revoke it immediately after use. That is the architectural shift from session-scoped access to per-action access, which is the practical meaning of zero standing privilege.
Practical implication: place policy enforcement at issuance time, not only at provisioning time.
Threat narrative
Attacker objective: The attacker aims to redirect a privileged agent into performing unauthorised actions or exfiltrating data through the access already held by the session.
- Entry begins when the agent processes untrusted content such as a webpage, email, or document that an attacker has shaped to influence its runtime decisions.
- Credential exposure occurs when the agent already holds a reusable key or token in memory, giving the attacker a live privilege surface to hijack.
- Impact follows when the manipulated agent uses that credential to reach systems, datasets, or APIs that exceed the original task boundary.

NHI Mgmt Group analysis
Standing privilege was designed for identities whose behaviour can be predicted between review cycles. That assumption fails when the actor is autonomous enough to select tools and timing at runtime, because access can be consumed, redirected, and abused before any governance process can observe it. The implication is not just tighter secrets hygiene, but a rethink of what it means for privilege to exist at all in an agent session.
Zero standing privilege is really an identity timing problem, not just a credential storage problem. The article correctly separates centralised secrets management from true ephemeral access. In NHI terms, the control gap is not where the secret lives, but whether the identity can still act with it outside the task boundary. Practitioners should read this as a shift from static entitlement control to issuance-time control.
Ephemeral credential trust debt: organisations keep inheriting access patterns built for deterministic workloads and then extending them to agentic systems that do not stay deterministic for long enough. That creates a governance debt where the access model lags the runtime model. The practical consequence is that privileged access programmes now need a task-scoped design assumption, not a session-scoped one.
Secrets managers and gateways form a useful ladder, but only per-action issuance closes the exposure window. The field should stop treating session-scoped controls as if they were final-state governance. A mature identity programme will use inventory and policy visibility first, then runtime mediation, then per-call revocation where the risk justifies it.
For agentic AI, accountability must follow the action, not the credential alone. Once agents can read untrusted content and trigger tool use at runtime, who owned the secret matters less than whether the access existed long enough to be misused. That shifts the identity governance conversation toward issuance boundary, action scope, and revocation timing.

What this signals
Agentic systems force identity teams to move beyond static provisioning and toward runtime governance. When a software actor can choose tools and process untrusted content in the middle of a task, the control question becomes whether any credential should survive past the current action.
Ephemeral credential trust debt: many programmes have inherited access patterns that assume session-long privilege is acceptable because workloads were previously deterministic. That assumption no longer holds for agents, so the strongest control point becomes credential issuance, not credential storage.
The broader signal for IAM and PAM teams is that access reviews alone will not close agent risk. If privilege can exist and disappear inside a single workflow, governance must shift toward registration, policy mediation, and revocation at action time, according to the 2026 Infrastructure Identity Survey
For practitioners
- Map which agent workflows still hold standing credentials Inventory agents that receive API keys, tokens, or certificates at startup and keep them for the full session. Prioritise the workflows that can reach customer data, finance systems, or production tooling.
- Separate secret storage from runtime privilege Use centralised secrets storage for governance visibility, but do not treat retrieval at session start as a sufficient control. Identify where the agent still retains access after the approved action ends.
- Move high-risk agent actions to per-call issuance For sensitive tools, require a gateway or broker to mint narrowly scoped credentials for each discrete action and revoke them immediately after use.
- Register every agent that can request credentials Make agent registration a prerequisite for access so unregistered systems cannot reach secrets. Use the inventory to review who has access to what and to spot dormant service accounts or stale agents.
- Rework access reviews around task boundary evidence Ask whether the identity held privilege long enough to be reviewed, or whether the access disappeared before any quarterly process could see it. Replace session-based assumptions with issuance-time evidence.
Key takeaways
- Agentic AI changes the access problem because the actor can make runtime decisions while holding a credential that was meant to be temporary or deterministic.
- The article distinguishes centralised secret storage from true zero standing privilege, which only exists when access is issued for one action and revoked immediately after use.
- For practitioners, the control priority is to remove reusable credentials from agent sessions and move enforcement to issuance time.

Key terms
- 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.
- Standing Privilege: Standing privilege is access that remains active even when no immediate task requires it. For NHI programmes, it is a common failure mode because long-lived credentials and persistent roles create unnecessary exposure. Reducing standing privilege usually means tighter expiry, on-demand access, and clearer review of who or what still needs access.
- Per-Action Issuance: Per-Action Issuance is a runtime control pattern in which a gateway mints a fresh, narrowly scoped credential for each individual action. It is the closest practical expression of ZSP for AI agents because it limits the life of the privilege to one approved call.
- Runtime Mediation: A control model where access is granted, checked, and potentially revoked at the moment an action is taken. For AI agents, runtime mediation is the practical alternative to one-time consent because decisions, context, and tool use can change during a session.
