Your employees are probably already using ChatGPT at work. They rewrite an email, summarize a long report, or ask for help with a formula in Excel. Often it happens without much thought about where the text they paste in actually ends up. The question for you as a business owner is therefore not whether it is being used, but how you make sure it happens responsibly.
The good news is that AI tools can be used safely at work. But it requires that you understand the risk and set up a few things before your employees are turned loose. Let us go through what actually matters.
What is the real risk?
The core problem is simple. When an employee pastes confidential information into a public model, you lose control over where that data goes. It could be a customer list, an unpublished quarterly report, source code, or an employee's health details. In the worst case, the information is used to train the model and can later surface in another user's answer.
For personal data there is an extra dimension: GDPR compliance. You are the data controller, and you are responsible for personal data not being sent to a third party without a legal basis and a data processing agreement. On top of that comes the loss of trade secrets, which can quietly weaken your competitive position.
Rule of thumb: If you would not post the information on a public bulletin board, it should not go into a free AI tool. That single sentence takes your employees a long way.
Free vs. paid: the decisive difference
This is where most people misunderstand ChatGPT. The security depends heavily on which version you use.
In the free and Plus versions, your conversations can, as of 2026, be used to improve the model by default. You can turn this off in the settings, but it requires that someone actually does it. The business products ChatGPT Team and Enterprise, as well as the API, do NOT use your data for training. That is the key distinction to understand.
The same principle applies to the other providers, and it is worth knowing if you are already invested in a platform. Microsoft 365 Copilot keeps your data inside your own Microsoft tenant, which fits neatly with a setup you may already run. Anthropic's Claude does not, as of 2026, train on commercial or API use by default. So no provider is safe or unsafe in itself. It comes down to the specific product and the agreement behind it.
If you already work in Microsoft 365, it is worth reading our guide to Microsoft 365 security, since Copilot inherits the security settings from your existing tenant.
5 rules for safe ChatGPT use at work
You do not need a large policy binder to get started. Five clear rules get you most of the way:
- Never enter personal or customer data in free tools. No passwords either. If in doubt, leave it out.
- Use business versions with a data processing agreement, so you have a legal footing and your data is not used for training.
- Turn off model training in the settings, even on paid personal accounts, as an extra safeguard.
- Classify what may be shared. Decide which types of information are fine, and which are off-limits.
- Keep a simple AI policy that everyone knows. One page that people actually read beats a thick document nobody opens.
These five rules are the practical core of a broader approach we describe on our page on AI, used safely. They cost nothing to introduce, and they remove the most common way data leaves a business by accident.
How IT-Connect helps
We are not a reseller of a single AI tool, and we have no interest in pushing you toward one specific brand. We assess the tools you already use, weigh them against your needs, and recommend the setup that makes sense for your business.
In practice we set up the business tenant correctly, so training and data sharing are configured the way they should be. We help draft a data policy your employees can actually understand, and we train the staff so they know what they may paste in and what they may not. The goal is that AI becomes genuinely useful in daily work without opening a door to data leaks.
You can read more about our approach on our hub page AI, used safely, where we go deeper into how businesses can benefit from AI without taking unnecessary risks.
Where to start? Begin with a short inventory of which AI tools are already in use in the business. You almost always find more than you expected, and that overview is the foundation for a policy that actually fits reality.
Frequently asked questions
Is ChatGPT GDPR-compliant?
It depends on which version you use. The free and Plus versions are not suited for personal data, because there is usually no data processing agreement, and because data can be used to improve the model. ChatGPT Team and Enterprise, and the API, can be used in a GDPR-compliant way when you sign a data processing agreement and control which data is shared. The responsibility always rests with you as the data controller.
Does ChatGPT use my data for training?
In the free and Plus version, your conversations can, as of 2026, be used to improve the model by default, but it can be turned off in the settings. In the business products ChatGPT Team and Enterprise, and via the API, your data is not used for training. Always check the terms of the specific version, since providers adjust them over time.
May employees use ChatGPT at work?
Yes, if it happens within clear boundaries. Set up a simple AI policy that describes which tools are approved, and what must never be entered, for example, personal and customer data or passwords. Without boundaries, people use the tool anyway, just without control over where the data ends up.
Is Microsoft Copilot or Claude safer than ChatGPT?
Not in themselves. Security depends on which product and which agreement you use, not on the brand. Microsoft 365 Copilot keeps data inside your Microsoft tenant, and Anthropic's Claude does not, as of 2026, train on commercial or API use by default. The same applies to ChatGPT Enterprise. Choose based on your existing setup and data processing agreements, not on the name of the model.
