What Is Shadow AI: And Why It Is Nothing Like Shadow IT

Shadow IT was about apps. Shadow AI is about behavior, data, and decisions being delegated to models your company never approved.

Every few years, security teams face a new version of the same problem: employees find a faster, easier way to do their jobs. IT finds out about it six months later, after the damage is done.

Shadow IT taught us that people will always route around friction. But what’s happening now with AI is fundamentally different, and treating it the same way is one of the most dangerous mistakes a security leader can make.

Shadow IT: The Original Sin

When Dropbox went viral inside enterprises in the late 2000s, CISOs scrambled. Employees were storing company files on personal cloud accounts. IT didn’t know. Security policies didn’t cover it. The fix was relatively straightforward: block the domain, migrate the data, issue a policy.

Shadow IT was a governance and storage problem. The data sat somewhere it shouldn’t. The solution was to find it, move it, and lock the door.

“Shadow IT was employees using Dropbox instead of the shared drive. Shadow AI is employees uploading your customer database to a free model to ‘summarize it faster.’”

That mental model (find the unauthorized tool, block it, move on) does not work for AI. And here’s why.

Shadow AI: A Completely Different Animal

Shadow AI isn’t just “unapproved software.” It’s unapproved cognition.

When an employee pastes your internal pricing model into ChatGPT to “make it easier to read,” several things happen simultaneously:

The data leaves your environment, potentially forever

It may be used to train the model you just fed it to

There’s no log, no audit trail, no timestamp

The output, and any decisions made from it, exist outside your governance framework

You have no idea it happened

ChatGPT, Claude, Gemini, Copilot, Perplexity plus every model that launches next month

Browser extensions with embedded AI capabilities

Native OS-level AI features (Windows Copilot, macOS Intelligence)

Any internal tool that quietly added an “AI-powered” feature

The model your developer is calling directly via API

What data is being sent to AI models and which models?

What decisions are being influenced or made by AI outputs?

Which AI agents have access to which systems?

When a human defers to an AI recommendation, is that visible anywhere?

That last point is the one that should keep CISOs up at night. Shadow IT left breadcrumbs. Shadow AI is designed, by default, to leave nothing.

Shadow IT vs. Shadow AI: A Side-by-Side

The differences are not cosmetic. They require entirely different governance strategies:

Shadow IT

Shadow AI

What it is

Unsanctioned apps & tools

Unsanctioned AI models & agents

Core risk

Data stored in wrong place

Data processed, inferred, and acted on

Audit trail

Logs exist (somewhere)

Often none; inference is invisible

Speed of exposure

Slow (data must be breached)

Instant (model inference is the breach)

Governance lever

Block the app

Govern the behavior + the model

Primary concern

Compliance & storage policy

IP leakage, model training, decision integrity

Why Blocking Doesn’t Work Anymore

The instinct to “just block it” made sense for Shadow IT. Block the Dropbox domain. Problem (mostly) solved.

Try that with AI. You’d need to block:

Even if you blocked all of that today but tomorrow it looks different. AI is not a destination. It’s becoming the operating layer of every application your employees already use.

You cannot govern what you cannot see. And you cannot see Shadow AI with Shadow IT tools.

What Governing Shadow AI Actually Requires

Shadow AI governance requires a shift from perimeter-based thinking to behavior-based thinking. Instead of asking “what apps are they using?”, the question becomes:

This is why KonaSense is built around the concept of an Agent Control Plane : a governance layer that sits above both your human workforce and your AI coworkers, giving you visibility and control over the full loop: what goes in, what comes out, and what actions get taken.

It’s not enough to know an AI tool exists in your environment. You need to know what it’s doing, who it’s doing it for, and whether anyone approved that.

The Uncomfortable Truth

Shadow AI is already inside your organization. Not because your employees are careless but because the tools are genuinely useful, the onboarding is invisible (it’s just a browser tab), and the governance frameworks haven’t caught up.

The companies that will be in control of their AI posture in 2026 aren’t the ones that banned AI. They’re the ones that built the infrastructure to govern it.

“You can’t block your way out of Shadow AI. You have to govern your way through it.”
