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.
Editorial analysis by NHI Mgmt Group, based on content published by BigID: “How to Conduct an Agentic AI Risk Assessment”.
Key questions
Q: What fails when agentic AI systems are assessed only for model risk?
A: The assessment misses the operating actor.
Q: Why do inherited permissions make AI agents harder to govern?
A: Because the agent’s authority is often borrowed from service accounts, API keys, machine identities, or user roles.
Q: What are the signs that an AI agent has more access than it needs?
A: Common signs include access to systems outside the declared task, frequent permission exceptions, policies that are broader than the observed workflow, and usage logs showing actions the agent did not need to complete its job.
Practitioner guidance
- Define an AI agent inventory Catalogue every approved, embedded, and shadow AI agent, including copilots, assistants, and autonomous workflows, so ownership and access can be reviewed systematically.
- Map inherited permissions to each agent Trace permissions through service accounts, APIs, machine identities, and user-role inheritance to identify where the agent’s effective access exceeds intended function.
- Classify the data each agent can reach Link agent access to sensitive-data categories such as customer records, financial information, regulated data, and intellectual property before approving production use.
Bottom line: Agentic AI risk now sits at the intersection of identity, access, and data context, not only model behaviour.

Agentic AI governance fails when identity is treated as secondary to model behaviour. The article reflects a wider industry mistake: organisations assess what an agent says before they assess what it can do. Once an agent can call APIs, read data, and trigger workflows, the governance question shifts to permissions, ownership, and control boundaries. The practitioner conclusion is that AI risk programs now need an identity-first scope.
A few things that frame the scale:
- Gartner predicts that more than 40% of agentic AI projects will be cancelled by the end of 2027, citing rising costs, unclear value and insufficient risk controls.
A question worth separating out:
Q: How do organisations decide whether AI agent access reviews should be automated or manual?
A: Organisations should automate the repetitive parts of access review when AI agents create large, fast changing permission sets, then reserve human judgment for high risk exceptions. Automated reasoning helps reduce reviewer fatigue and surface outliers sooner, but it still needs policy guardrails, clear ownership, and escalation paths for privileged or sensitive access.
