TL;DR: PlainID argues that AI agents make static permissions and role-based models fall behind because access decisions have to follow runtime intent across tools, APIs, data retrieval, and responses. Zero standing privilege is the governance pivot because authorisation must be continuously enforced, not assumed at provisioning time.
Editorial analysis by NHI Mgmt Group, based on content published by PlainID: “Secure Agentic AI with Runtime Authorization”.
Key questions
Q: When should organisations use runtime authorization for AI agents?
A: Use runtime authorization when agent behavior can change based on context, tools, or delegated workflows.
Q: Why do excessive permissions create more risk in agentic AI systems?
A: Excessive permissions raise risk because agents can act autonomously, chain tool calls, and trigger downstream systems faster than a human can intervene.
Q: What is the difference between zero standing privilege and runtime authorisation?
A: Zero standing privilege removes durable access between tasks, while runtime authorisation decides whether a specific action is allowed right now.
Practitioner guidance
- Define runtime policy checkpoints Place authorisation checks at prompt handling, retrieval, tool invocation, and response generation so each state change is evaluated before execution continues.
- Convert standing access into task-scoped access Replace persistent agent permissions with narrow, task-bound grants that disappear when the workflow completes or the session closes.
- Bind decisions to identity, intent, and context Require the policy engine to assess who the agent is, what it is trying to do, and the current data or tool context before approving action.
Bottom line: AI agents change authorisation from a provisioning-time decision into a live control problem because they can select actions across tools, APIs, and data sources during execution.

Static authorisation is the wrong mental model for agentic execution. AI agents do not merely consume access, they choose actions across multiple resources inside a live workflow. That means entitlement at provisioning time is an incomplete security answer, because the relevant decision is whether each runtime action still fits policy. Practitioners should treat authorisation as an execution-time control plane, not a pre-approved state.
A few things that frame the scale:
- 67% of organisations still rely heavily on static credentials despite the risks they pose to agentic AI deployments, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: How can teams tell whether agentic access controls are actually working?
A: Look for evidence that every privileged action is logged with actor type, target resource, and policy decision, and that denied requests are being blocked before execution. If you can only see the login and not the downstream action, the control is too weak for agentic use.
