TL;DR: AI agents now schedule meetings, move money, provision infrastructure, and execute multi-step workflows, which makes identity and privilege abuse a primary risk in agentic systems, according to WorkOS and the OWASP GenAI Security Project. Least agency is not a tuning parameter anymore; it is the assumption boundary that fails when agents inherit human credentials and act at machine speed.
Editorial analysis by NHI Mgmt Group, based on content published by WorkOS: “The OWASP Top 10 for agentic applications: What developers building with AI agents need to know”.
Key questions
Q: What breaks when AI agents are given broad standing access?
A: Broad standing access breaks governance because the agent can move from one task to another without a fresh authorization check.
Q: Why do AI agents complicate privilege management?
A: AI agents complicate privilege management because they can execute actions autonomously, chain tools, and consume access without the normal human pauses that create review opportunities.
Q: How can security teams tell whether agent permissions are too broad?
A: The clearest signal is whether the agent can still complete its job after permissions are reduced in a sandbox.
Practitioner guidance
- Define task-scoped agent identities Give each agent a dedicated managed identity with a narrow purpose, explicit resource boundaries, and expiry aligned to the task it performs.
- Remove borrowed human sessions Stop allowing agents to inherit end-user credentials or shared service accounts for autonomous actions, because that erases attribution and widens blast radius.
- Enforce policy at tool invocation Check every tool call against allowed actions, schemas, and resource scopes before execution, not after the agent has already chained several steps.
Bottom line: Agentic AI turns privilege into a runtime control problem because agents can choose tool sequences and act across systems without waiting for human approval.

Least agency is now an identity governance boundary, not a design preference. The article correctly identifies that agentic systems change the meaning of privilege because action is no longer fully predictable at provisioning time. Traditional least privilege assumes access can be bounded by role and job description, but agentic behaviour collapses that assumption once tool choice and execution timing move to runtime. Practitioners should treat this as a governance shift, not a tuning exercise.
A few things that frame the scale:
- 70% of organisations grant AI systems more access than they would give a human employee performing the exact same job, according to the 2026 Infrastructure Identity Survey.
- Systems with least-privileged AI access had a 17% incident rate vs 76% for over-privileged systems. Organisations failing to scope AI access properly are 4.5x more likely to experience a security incident, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: Should organisations separate agent identities from human identities?
A: Yes. Separation preserves attribution, limits blast radius, and lets teams revoke or narrow the agent without disrupting the user who authorised it. If an agent shares the same session or credentials as a person, every audit trail, approval rule, and incident response step becomes harder to trust.
