TL;DR: Nexis argues that AI Act readiness cannot stop at inventorying models, copilots and agents, because a register records intended use but cannot stop runtime access drift, jurisdictional leakage or policy violations when data context changes. The control boundary shifts from documentation to dynamic, data-aware authorization.
Editorial analysis by NHI Mgmt Group, based on content published by Nexis: “The AI Register Is Not Enough”.
Key questions
Q: How should organisations govern AI agents when the register no longer matches runtime behaviour?
A: They should treat the register as evidence, not enforcement.
Q: Why do AI registers fail to control regulated data access in practice?
A: Because a register records declared scope, while access risk changes when the agent touches different data.
Q: What breaks when AI governance and IAM use different policy definitions?
A: The organisation gets compliant records without enforceable controls.
Practitioner guidance
- Define runtime policy triggers for agent requests Tie authorization to task, data class and jurisdiction so policy evaluates every request instead of every registration entry.
- Separate registry evidence from enforcement Keep the AI register as governance inventory, but require a policy decision point before any agent can reach regulated data.
- Align GRC classifications with IAM attributes Use the same data-classification labels in governance records and in the identity policies that approve or deny access.
Bottom line: The article shows that an AI register is a governance artifact, not a runtime control, and that distinction is where many readiness programmes fail.
What's in the full article
Nexis's full article covers the operational detail this post intentionally leaves for the source:
- How the AI register is structured for owners, risk classes and documentation workflows
- The policy-based authorization logic that evaluates task, data class and jurisdiction together
- The runtime enforcement model for blocking external model calls to regulated data
- Why audit traceability and access control need to share the same governance definitions

Static AI registers are necessary but insufficient because they describe intent, not authority. The article correctly identifies a familiar governance failure: organisations stop at inventory and assume compliance is established. That works for documentation, but not for access control, because an agent can change scope after registration. The implication is that AI governance needs a runtime enforcement model, not just a record of approved use.
A few things that frame the scale:
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: Should organisations prioritise dynamic authorization over expanding the AI register?
A: Yes. Expanding the register helps with visibility, but dynamic authorization prevents the higher-risk event itself by denying disallowed access before data leaves the control boundary. Without that runtime gate, inventory growth only improves documentation.
