Shadow AI is a registry problem

You cannot govern AI systems you cannot name. That is the shadow AI problem: teams adopt assistants, automation tools, document processors, browser extensions, agents, and SaaS copilots faster than governance teams can inventory them.

A spreadsheet is a start, but it is not a registry. A useful AI system registry is live, owned, searchable, and exportable.

What belongs in the registry

Every entry should answer practical questions:

• What is the system called and who owns it?
• What business process does it support?
• Is it internal, vendor-hosted, embedded in SaaS, or open source?
• Which model or provider does it use?
• What data does it access?
• Does it process personal, confidential, financial, legal, or regulated data?
• What is the risk classification?
• What human oversight exists?
• Which logs, policies, evaluations, and incidents are linked?
• Can the organization suspend it quickly?

The registry should cover formal systems and shadow systems. Otherwise, the highest-risk tools may be exactly the ones nobody has reviewed.

The workflow that works

Discovery should combine procurement data, SSO logs, network signals, endpoint telemetry, finance spend, browser extensions, and interviews with business teams. Each system then moves through a lifecycle: discovered, profiled, classified, documented, approved, monitored, and retired.

Do not make legal or compliance fill every field manually. Product owners should provide context. Security should enrich access and data-flow signals. Engineering should expose telemetry and model dependencies. Compliance should own classification and approval criteria.

What makes it regulator-ready

A regulator-ready registry can export structured data on demand. It should include system name, purpose, owner, vendor, risk level, deployment domain, data categories, model/provider, documentation status, oversight status, incident history, and review date.

The goal is not bureaucracy. It is operational clarity. When a regulator, client, or board asks “where are we using AI?”, the answer should take minutes, not weeks.
