Shadow AI Is Bigger Than Unsanctioned AI Tools

Shadow AI is often described as the next version of shadow IT. The comparison is useful, but incomplete.

Gartner has called attention to shadow AI as a growing enterprise risk, particularly as employees use prohibited public GenAI tools without security or IT oversight. That concern is real. Unauthorized AI usage can expose sensitive data, create compliance gaps, and leave security teams without a clear view of where company information is going.

But shadow AI is becoming broader than the use of unapproved tools. In the enterprise, the harder question is what happens after AI has been approved.

Many organizations are now moving from AI experimentation to sanctioned AI adoption. They are rolling out enterprise AI assistants, coding agents like Claude Code and Codex, productivity tools, copilots, connectors, and internal agents. These tools may be approved, paid for, and deployed through official channels, but that does not automatically mean security teams have visibility into how they are being used.

What does shadow AI mean in the enterprise?

Shadow AI refers to AI usage that lacks clear visibility, governance, or security oversight. In practice, that can include both unsanctioned AI tools and sanctioned AI systems with hidden usage patterns.

An employee pasting company data into an unapproved AI app is the obvious example. A less obvious example is an employee using an approved AI assistant in a way that creates business, privacy, or data risk. They may use it to search company files for personal purposes, summarize sensitive internal documents, or connect it to systems that were never meant to be part of that workflow.

The risk is not limited to whether the AI tool is allowed. The risk also depends on what the AI can see, what it can infer, which connectors are enabled, and what actions it can take.

Why does sanctioned AI still need visibility?

Sanctioned AI can still create blind spots. A company may approve an AI assistant, coding agent, or productivity tool, but approval does not automatically answer the governance questions that matter.

Security teams still need to know which employees are using the tool, what connectors are enabled, what files are being accessed, whether labels like INTERNAL USE ONLY or CONFIDENTIAL are being respected, and whether the AI is being used in ways that align with company policy.

For example, an employee might use an enterprise AI assistant to search across internal documents for a part-time job outside the company. Another user might connect an AI tool to Google Drive, Microsoft OneDrive, or SharePoint and unintentionally expose confidential files through summaries, outputs, or downstream workflows.

These are not only shadow IT problems with a new name. They are visibility and governance problems inside the sanctioned AI environment.

How do AI-SPM and Agent-SPM help with governance?

As AI adoption spreads, organizations need a more precise way to manage AI posture. AI-SPM and Agent-SPM help security teams move from broad AI policy to continuous visibility and governance.

AI-SPM helps teams understand where AI is being used, what data it touches, and whether usage aligns with policy. Agent-SPM goes deeper into the agentic layer, where AI systems can call tools, use connectors, interact with MCP servers, and take action across enterprise workflows.

This matters because agentic AI changes the governance model. Security teams are no longer only asking whether an AI tool was approved. They also need to understand the agent’s access, permissions, connected systems, autonomy, and potential blast radius.

What should security teams do first?

Security teams should start by building visibility across both unsanctioned and sanctioned AI use. That means identifying active AI tools and agents, mapping users and owners, reviewing connectors, understanding data access, and classifying risk based on what each AI system can do.

From there, teams can create governance policies that are specific enough to matter. Some AI use cases may only require ownership and documentation. Others may require tighter permissions, adversarial testing, runtime monitoring, or limits on which files, labels, and systems an agent can access.

Shadow AI is no longer only a question of whether employees are using unapproved tools. The bigger question is whether the enterprise can see and govern what AI is doing after access has been granted.

In the agentic era, sanctioned does not always mean visible. And without visibility, governance is mostly guesswork.
