TL;DR: Agent security is a runtime discipline, not a policy exercise, Trust3 reports, and autonomous agents create extra identity risk through delegated credentials and tool access. Separate containment and response are needed so approved boundaries still hold in execution.
Editorial analysis by NHI Mgmt Group, based on content published by Trust3: “Agent Security Is Not AI Governance: Why Conflating The Two Is A Risk Enterprises Can’t Afford”.
Key questions
Q: Why do AI agents increase non-human identity risk?
A: AI agents increase non-human identity risk because they can execute many actions quickly once they inherit a credential or tool permission.
Q: What are the signs that agent security controls are lagging?
A: Common signs include agents appearing in production without clear ownership, unclear visibility into tool calls, and no reliable way to reconstruct what a session changed.
Q: What breaks when AI agent governance is treated as access control?
A: The control boundary breaks first.
Practitioner guidance
- Separate AI governance from agent security Define distinct ownership, controls and review cycles for governance, runtime containment and incident response so the two disciplines are not merged into a single approval workflow.
- Inventory every agent tool connection Map databases, code runners, messaging systems and API endpoints that agents can reach, then classify each as a privileged access path that needs explicit control.
- Apply least privilege to agent identities Scope each agent to the smallest usable set of credentials, APIs and workflow permissions, with separate access for test, pilot and production environments.
Bottom line: AI governance and agent security are not interchangeable, because one sets policy and the other constrains runtime behaviour in live systems.

AI governance and agent security are different control planes, not competing labels for the same risk. Governance sets the rules for responsible AI use, but it does not constrain live agent behaviour inside enterprise systems. Once an agent can browse, call APIs, or execute code, the governance question becomes secondary to whether identity, privilege and action boundaries are enforced at runtime. Practitioners should stop treating policy as a substitute for operational containment.
A few things that frame the scale:
- 54% of organisations are actively deploying AI agents across workflows, yet only 21% report a mature governance model for agentic AI.
A question worth separating out:
Q: Should organisations treat AI governance and AI security as the same thing?
A: No. Governance answers who approved the system, what data it may use, and which policy applies. Security answers whether an attacker can misuse the system, steal data, or abuse credentials. The two functions need different owners, different evidence, and different response workflows.
