TL;DR: Shadow AI stays outside policy when AI tools and agents move data across endpoints and APIs beyond the model Cyberhaven describes. Governance has to shift to runtime discovery, continuous inventory, and data-layer enforcement for autonomous tools.
Editorial analysis by NHI Mgmt Group, based on content published by Cyberhaven: “Shadow AI Is Not a People Problem. It's a Governance Problem”.
By the numbers:
- Endpoint agents grew 509% in 2025, according to Cyberhaven.
Key questions
Q: Why do AI agents make traditional governance controls less effective?
A: AI agents can perform work without a human making each step of the decision, which weakens policies built around user intent and approval checkpoints.
Q: How do security teams know if shadow AI is actually under control?
A: Security teams know shadow AI is under control when they can inventory every agent, model workflow, and tool connection, then map each one to an owner and access scope.
Q: What breaks when shadow IT grows inside cloud and AI teams?
A: Shadow IT breaks visibility and control.
Practitioner guidance
- Implement continuous AI tool discovery Track browser-based tools, locally installed agents, and MCP-connected services across managed and unmanaged endpoints so governance is based on runtime reality, not procurement records.
- Move enforcement to the data layer Control access based on what data an AI tool can read, prompt, or export, instead of depending only on destination blocks and approved application lists.
- Classify AI agents as governed non-human actors Assign ownership, review cadence, and access boundaries to autonomous tools so they are managed like other non-human identities with operational privileges.
Bottom line: Shadow AI persists because policy-based governance assumes human-initiated behaviour, while AI tools and agents can move data across endpoints and APIs outside that model.

Shadow AI is now an NHI governance problem, not just an AI policy problem. The article makes clear that the issue is not employee intent but runtime access by tools and agents that behave like non-human actors. That means the governance boundary has shifted from acceptable use to lifecycle control over access, data handling, and inventory. Practitioners should treat AI agents as governed identities whose behaviour must be continuously observed.
A few things that frame the scale:
- 52% of respondents see AI security decision-making power shifting toward platform and infrastructure teams rather than the executive suite, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: When should organisations treat an AI system as a non-human identity?
A: Treat an AI system as an NHI when it can authenticate, request tools, or perform actions without direct human supervision. At that point it needs inventory, lifecycle, least privilege, monitoring, and revocation controls just like other machine identities.
