Your Employees Are Sharing Sensitive Data with AI Without Realising It
68% of employees use AI at work. Half of them paste in confidential data. Here's how to protect your company.
A sales rep copies their client database into ChatGPT to draft emails. An HR manager pastes in CVs to screen them. An accountant uploads financial statements to analyse them. Every day, sensitive data leaves your company without anyone noticing.
And this isn't anecdotal. According to Cisco and Microsoft studies, 68% of employees use AI at work, and 45% share confidential data with it. In your company, it's probably already happening.
Did you know?
68% of employees use AI at work, and 45% share confidential data with AI tools — often without realising the risks to GDPR compliance and data security.
What Your Teams Are Sharing (Without Thinking)
The scenarios look the same regardless of industry:
Client data. Names, emails, phone numbers copied to "improve a text" or "segment a list". The AI tool ingests them, stores them, and sometimes uses them for training. Your clients never gave consent for that.
Contracts and internal documents. A lawyer pastes in a contract to summarise it. A manager uploads a strategic report to rephrase it. Confidential clauses are now sitting on external servers, beyond your control.
Source code. Developers ask AI to fix or optimise proprietary code. Samsung learned this lesson the hard way when engineers shared confidential code with ChatGPT. Three incidents in a single month.
HR and financial data. Salaries, performance reviews, accounting statements. Information that, if leaked, exposes the company to GDPR lawsuits and a major internal trust crisis.
The most alarming part? Most employees don't even realise they're taking a risk. They simply want to be more efficient. It's a commendable intention, but the consequences can be devastating.

3 Immediate Measures
No need for a 6-month project. Start this week:
1. Inventory your AI usage. Send an anonymous survey to your teams. What tools are they using? For which tasks? With what data? You'll be surprised by the answers. Most leadership teams vastly underestimate actual adoption.
2. A clear, communicated AI charter. Define the authorised tools, the prohibited data, and the responsibilities. Display it, communicate it, keep it alive. A charter buried in a drawer protects no one.
3. Train your teams. A single awareness session dramatically changes behaviour. The rate of sensitive data sharing drops by 60% after just one well-designed training session. The investment pays for itself with the first incident avoided.
Our AI Governance consultancy helps you implement all three measures — from inventory to training — available as a lunch & learn, half-day, or conference.
