TL;DR: AI agents are already reading data, calling APIs, and taking actions in production, which shifts the core question from capability to trust, according to Drata. Continuous oversight, inline enforcement, and tamper-evident evidence are becoming the practical controls for governable AI behaviour, not periodic review.
Editorial analysis by NHI Mgmt Group, based on content published by Drata: “Human Expertise Plus AI Governance Equals Trustworthy AI”.
Key questions
Q: What breaks when AI agent access is not re-evaluated in real time?
A: The main failure is privilege drift.
Q: Why do AI agents need a human owner?
A: AI agents need a human owner because accountability does not scale without a stable person or team responsible for their permissions, boundaries, and outcomes.
Q: How can organisations tell whether AI agent governance is actually working?
A: Look for evidence that agent access is ephemeral, traceable, and constrained at the action level.
Practitioner guidance
- Define a named human owner for every agent Map each agent to one accountable person or team, then require that ownership to appear in policy records, access decisions, and review workflows.
- Register agents before they can act Create a complete inventory of agents, their scopes, and the systems they can touch at the point of creation, so governance starts with discovery rather than after-the-fact reconciliation.
- Enforce policy before execution Use inline controls that evaluate each action against approved policy before the action runs, rather than relying on notifications or retrospective review after the fact.
Bottom line: AI agent governance now depends on controls that operate while the agent is acting, because delayed review cannot contain drift or preserve accountability.

Continuous oversight is now the baseline control for AI agents, not a maturity bonus. Periodic review assumes behaviour is stable long enough to be sampled and certified, but agentic systems operate in the same moment they are evaluated. That means governance has to move to the point of action, where policy can still block, shape, or evidence the decision. The practitioner implication is clear: if oversight only exists after execution, it is not oversight of an AI agent.
A few things that frame the scale:
- Only 44% of organisations have implemented any policies to manage their AI agents, despite 92% agreeing that governing AI agents is critical to enterprise security, according to the 2026 Infrastructure Identity Survey.
- Only 37% of organisations had policies for managing AI or detecting shadow AI, according to IBM's 2025 Cost of a Data Breach Report.
A question worth separating out:
Q: Should teams enforce AI agent policy before or after execution?
A: Teams should enforce policy before execution whenever an agent can make independent actions that affect data, systems, or approvals. After-the-fact review can support assurance, but it cannot prevent an out-of-bounds action or preserve the original decision context once the action has already happened.
