TL;DR: Agentic AI risk assessment has moved beyond model behavior because agents can inherit permissions, access sensitive data, and execute workflows across enterprise systems, according to BigID. The governance gap is now identity and data context, not prompt quality, because autonomous action expands exposure faster than traditional AI review models can track.
NHIMG editorial — based on content published by BigID: Agentic AI risk assessment and governance
By the numbers:
- 80% of organisations report their AI agents have already performed actions beyond their intended scope, including accessing unauthorised systems, sharing sensitive data, and revealing access credentials.
Questions worth separating out
Q: What breaks when AI agents are given access without identity governance?
A: What breaks is accountability.
Q: Why do AI agents complicate least privilege controls?
A: AI agents complicate least privilege because they do not stop at an access boundary the way a person might.
Q: How do security teams know if an AI agent is operating outside its approved role?
A: Teams should compare actual workflow behaviour against the approved use case.
Practitioner guidance
- Build an AI identity inventory Record every agent, copilot, assistant, and autonomous workflow with its owning team, business purpose, underlying account, and approval history.
- Separate inherited access from intended access Trace each agent back to the user role, service account, machine identity, or API grant that enabled it, then compare that path to the minimum access required for the workflow.
- Classify reachable data before granting production access Evaluate whether the agent can reach customer records, financial data, intellectual property, or regulated information, and use that classification to prioritise approval, restriction, or blocking decisions.

AI agents are already operating as non-human identities, and that is the right governance frame. The article is strongest when it treats agents as entities with identity, permissions, activity, and lifecycle state rather than as a narrow AI model problem. That framing aligns agentic AI with IAM and PAM controls, especially where access is inherited from service accounts, APIs, or user roles. Practitioners should govern agents through identity lifecycle discipline, not model-only review.
A question worth separating out:
Q: Who is accountable when an AI agent causes a security incident?
A: Accountability should sit with the business owner, the system owner, and the security function together, because agent behaviour crosses operational boundaries. Organisations need a defined owner for approval, monitoring, and retirement, plus audit evidence that shows what the agent accessed and why.
