TL;DR: Shadow AI is creating an enterprise control gap because employees are already using personal AI tools and agents outside approved governance, according to Tumeryk. AI observability and prompt-level policy enforcement now matter if organisations want visibility into tool use and agent activity.
Editorial analysis by NHI Mgmt Group, based on content published by Tumeryk: “Shadow AI Is a bigger problem than you think”.
By the numbers:
- Roughly 78% of AI users at work are bringing their own AI tools, according to Tumeryk.
Key questions
Q: Why do endpoint agentic AI tools create more governance risk than chat-only GenAI?
A: Endpoint agentic AI can act inside a user’s session, move data, and trigger downstream actions, which expands the effective privilege boundary.
Q: What are the signs that shadow AI is already operating in an organisation?
A: Common signs include sudden productivity jumps in a team, unusual data uploads to external AI platforms, and unexplained API calls or suspicious queries to third-party services.
Q: How should security teams govern shadow AI without blocking productivity?
A: Use visibility-based controls instead of blanket bans.
Practitioner guidance
- Define an approved AI tool baseline Publish a sanctioned list of models, copilots, extensions, and agent platforms, then block or review everything else through policy and access controls.
- Inventory every AI interaction path Identify where employees use personal accounts, browser extensions, IDE plugins, and embedded copilots so you can see which data paths are actually in use.
- Move controls to the prompt and tool layer Set policy for what data can be entered, which tools agents may call, and which actions require review before execution.
Bottom line: Shadow AI is creating an enterprise control gap because employees are already using personal AI tools and agents outside approved governance.

Shadow AI is now a governance failure, not a user-behaviour issue. The central mistake is treating unsanctioned AI use as a policy compliance problem when it is actually an identity and access control problem. If the organisation cannot bind the user, device, model, and data flow together, it cannot govern the activity at all. That makes discovery and auditability the minimum viable control, not an optional enhancement.
A few things that frame the scale:
- Only 13% of organisations feel extremely prepared for the reality of agentic AI despite the majority racing toward autonomous adoption, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: How do data governance and identity governance intersect in AI programmes?
A: They intersect at the point where systems decide what data to trust and who is accountable for that trust. Identity teams bring ownership, approval and review discipline, while data governance brings classification, lineage and context. AI programmes need both, because access without trustworthy context still produces poor decisions.
