TL;DR: AI can dynamically compose actions across live data, and Delinea’s October 2025 analysis shows that orphaned agents, exposed session tokens, and overly broad access create breach and compliance risk when authorization is reduced to a single gate. The real issue is that identity programmes still assume access is stable, reviewable, and human-paced.
Editorial analysis by NHI Mgmt Group, based on content published by Delinea: “It’s guardrails, not gates, that balance AI innovation and security”.
Key questions
Q: What breaks when AI agents rely on a single authorization gate?
A: A single gate breaks when the agent can keep acting after the initial decision, because runtime behaviour can diverge from the original approval.
Q: Why do exposed session tokens create such a high-risk path for AI workflows?
A: Because a session token can let an attacker or rogue process impersonate an active user and inherit whatever the session can already reach.
Q: When does an AI agent become a governance problem instead of an automation benefit?
A: An agent becomes a governance problem when it can discover secrets, call privileged APIs, or affect production without continuous oversight.
Practitioner guidance
- Define AI agent ownership and offboarding criteria Assign a named business owner, a technical owner, and a retirement trigger for every agent that can access live systems or customer data.
- Separate authentication from authorization reviews Review what the agent can do after access is granted, including session commands, tool use, and asset sensitivity, rather than treating login as the control outcome.
- Limit the blast radius of live-data agents Constrain the identities, tokens, and target assets that an agent can touch so a compromised session cannot pivot into customer data, API keys, or private keys.
Bottom line: AI agents change the risk model because they can continue making access decisions inside a session, not just at login.

Gate-based authorization is the wrong control shape for AI agents: a single yes-or-no access decision was designed for sessions that stay within predictable human or machine intent. That assumption fails when the actor can dynamically chain actions, select tools, and continue making decisions after the gate has opened. The implication is not simply that more approvals are needed. It is that authorization must be evaluated at the point of action, not only at the point of entry.
A question worth separating out:
Q: How should security teams bound AI agent risk in privileged sessions?
A: Teams should bound the agent by session-level policy, not by trust in the model or the initial login. That means limiting target assets, watching commands in real time, and using intent and asset sensitivity to decide whether the action should continue. If the session can move beyond the approved use case, the control boundary is too loose.
