Your Employees Are Already Using AI. Do You Know Where Your Data Is Going?

Tuesday 20th October 2026

Picture a Tuesday morning. A marketing manager pastes a draft client proposal into a free AI tool to "tighten it up". An analyst uploads a spreadsheet to get a quick summary. A developer asks a chatbot to debug a snippet of proprietary code.

Nobody is acting maliciously. They're just trying to work smarter. But your security team has no idea any of it happened.

And it isn't only people anymore. AI agents are now doing the same on their behalf, connecting to tools and moving data with the same access, and no one is watching.

Welcome to the world of Shadow AI.

Attackers go for people first

For years, cybersecurity has focused on protecting infrastructure, applications and data. Yet one truth hasn't changed: attackers still target people first, because people are where decisions get made.

We're curious. We experiment and adapt, and that creativity drives innovation and business growth. It's also what makes us vulnerable. Generative AI has given that curiosity a powerful new outlet, and most organisations aren't ready for it. Now those same people are deploying AI agents that act in their name, with their credentials and their access. Human risk and agent risk are becoming one problem.

The numbers are hard to ignore

  • 80% of employees are using unapproved AI tools at work
  • 57% admit to entering sensitive information into generative AI platforms
  • 69% of organisations suspect Shadow AI activity but can't confidently say where or how it's happening
  • 20% of security breaches now involve some form of Shadow AI

The message is clear: you can no longer assume you know where your data is going, or whether a person or an AI agent is behind it.

Your data protection strategy has a blind spot

Most data protection strategies were built for a pre-AI world. Data Loss Prevention (DLP), CASB and governance tools were never designed to inspect browser-based GenAI prompts, copy-and-paste activity, unsanctioned AI applications or the rapid rise of AI agents.

The result?

  • Sensitive information goes unclassified
  • AI interactions happen outside traditional controls
  • AI agents act with employee access and permissions, largely unseen
  • Acceptable Use Policies become guidance documents rather than enforceable controls

And the questions keep piling up. Which AI tools are being used? What data is being shared? Who (or what) represents the greatest risk? How do we encourage innovation without compromising security?

Blanket blocking of AI isn't the answer

The instinctive reaction is to shut it all down. But AI is now a genuine competitive advantage, and blanket bans rarely work long term. People find workarounds, and Shadow AI simply grows in the dark. Restrictions still have a place, but they need to adapt to the risk: coach the first-time mistake, block the repeat high-risk one.

The smarter move is visibility first, adaptive governance second.

From guesswork to evidence

This is where Mimecast Incydr Shadow AI Detection comes in. Incydr delivers adaptive data protection built for the AI era, with visibility into AI interactions across endpoints, browsers and desktop applications. Security teams can see:

  • Which AI tools and agents employees are using
  • What information is being shared
  • Where sensitive data may be exposed
  • Which users and agents present the greatest risk

Instead of guessing where Shadow AI exists, you can find it, understand it and govern it.

Turning human and agent risk into managed risk

Mimecast's approach is about adaptive governance, not blanket restriction. With Incydr, organisations can:

  • Get visibility from day one, without complex policy creation
  • Apply adaptive controls that educate, allow with audit, or block activity based on real user context and risk, whether a person or an AI agent is behind it
  • Align AI adoption with data protection requirements and business objectives
  • Extend governance to AI agents and agentic workflows without needing a new platform

What it means for your business

  • Confidence for leadership: clear, evidence-based visibility into AI usage for boards, regulators and auditors
  • Innovation without unnecessary risk: employees get the benefits of AI while sensitive information stays protected
  • Future-ready governance: a foundation that supports today's generative AI tools and the AI agents already working alongside your people
  • Reduced data exposure: acceptable use policies turned from recommendations into adaptive, enforceable controls, backed by real-world evidence

The question has changed

AI is transforming how organisations operate, and reshaping the human risk landscape with it, as employees hand more and more work to AI agents. The question is no longer whether your employees (and their agents) are using AI. It's whether you have the visibility and adaptive controls to manage it.

With Mimecast Incydr and the expertise of Bytes, you can embrace AI innovation while keeping control of your most valuable asset: your data.
