TL;DR: AI agents are effectively operating as delegated identities across endpoints, SaaS platforms, and the “mushy middle” of productivity tools, with long-lived OAuth and SAML grants creating persistent access paths that security leaders often do not fully see, according to Reveal Security. The identity model is shifting faster than conventional IAM review cycles, because agents can act as the user while retaining permissions long after the original task ends.
NHIMG editorial — based on content published by Reveal Security: What Security Leaders Should Actually Understand About AI Agents
Questions worth separating out
Q: How should security teams govern AI agents that can access enterprise systems?
A: Security teams should govern AI agents as non-human identities with explicit ownership, scoped privileges, and continuous monitoring.
Q: Why do AI agents create new risk in non-human identity management?
A: AI agents create risk because they operate as software identities with delegated authority, but many organisations do not track them with the same discipline applied to users or service accounts.
Q: What breaks when agent access is treated like a normal service account?
A: You lose visibility into why a specific call was allowed, which context justified it, and whether the action still made sense at the time it executed.
Practitioner guidance
- Inventory every agent-touchpoint across identity, SaaS, and desktop layers Build a single register of where agents can authenticate, what data they can reach, and which human or service principal granted the access.
- Constrain consent screens to the minimum task scope Require task-specific approval boundaries for agents that request mail, file, calendar, chat, or desktop permissions.
- Shorten token lifetime and force explicit re-authorization Set tighter expiry windows for delegated tokens used by agents and remove any assumption that a one-time approval is acceptable for ongoing use.

Agent identity exposes a delegation gap that classic IAM reviews were never designed to close. Human access review processes assume a person can be certified, challenged, or removed through a normal governance cadence. That assumption weakens when a software agent can acquire broad permissions, act immediately, and keep using them without a durable human workflow in the middle. The implication is that agent governance cannot inherit human review mechanics unchanged.
A few things that frame the scale:
- Only 1.5 out of 10 organisations are highly confident in their ability to secure NHIs, compared to nearly 1 in 4 for securing human identities, according to The State of Non-Human Identity Security.
- Another finding from our research shows that 85% of organisations lack full visibility into third-party vendors connected via OAuth apps, which underscores how quickly delegated access becomes ungoverned at runtime.
A question worth separating out:
Q: Who is accountable when an AI agent uses delegated access incorrectly?
A: Accountability should follow the delegated authority chain, not stop at the agent label. The relevant owners are the teams responsible for the human identity, the service identity, the workflow, and the policy that allowed the action path. If those responsibilities are not explicit, incident review will be incomplete and remediation will focus on the wrong layer.
