TL;DR: AI agent security expands the attack surface because agents can act across tools, APIs, and workflows, with risks including prompt injection, excessive permissions, supply chain compromise, and weak runtime monitoring, according to WitnessAI. Traditional IAM controls still matter, but autonomous execution makes policy, observability, and accountability the decisive control plane.
Editorial analysis by NHI Mgmt Group, based on content published by WitnessAI: “AI Agent Security: Protecting the Next Generation of Intelligent Workflows”.
Key questions
Q: What breaks when an AI system can choose tools and actions on its own?
A: What breaks is the assumption that access can be safely provisioned once and reviewed later.
A: AI agents become high risk when standing access and persistent secrets let them act beyond the task they were meant to perform.
Q: What are the signs that AI agent security controls are too weak?
A: Common warning signs include agents accessing systems or data outside their intended scope, sharing sensitive information inappropriately, and using credentials or tools without clear justification.
Practitioner guidance
- Define agent identity as a governed subject Inventory every AI agent, the tools it can call, the data it can reach, and the human or service owner accountable for its behaviour.
- Tighten tool-scoped authorisation Map each agent to the minimum set of APIs, datasets, and workflows required for its task, and remove broad reusable access wherever possible.
- Instrument runtime behaviour Capture agent action sequences, API calls, credential use, and abnormal automation loops so that misuse is visible before lateral spread occurs.
Bottom line: AI agents create a governance problem that extends beyond authentication because they can decide how to use access while they are already inside a workflow.

Traditional IAM controls stop at the point where AI agents begin making runtime decisions. Access models built around fixed identities and reviewable entitlements assume that the subject of control is stable long enough to classify and certify. That assumption weakens when the actor can choose tools, sequences, and timing inside a live workflow. The implication is that IAM and governance teams must treat agent execution as an identity event, not just the entitlement that enabled it.
A few things that frame the scale:
- Gartner predicts that more than 50% of successful cyberattacks against AI agents through 2029 will exploit access control weaknesses.
A question worth separating out:
Q: How should security teams govern scheduled AI agents across IAM, PAM, and NHI programmes?
A: Treat each routine as an identity with an owner, a narrow scope, an expiry path, and an approval boundary for any irreversible action. Then apply the same lifecycle discipline you would use for other non-human identities: inventory, scoping, review, and offboarding. If it can run unattended, it needs unattended governance.
