Using ChatGPT Safely in Business
ChatGPT is wildly popular in the workplace, but before you roll it out broadly you need to know what happens to your business data — and how to use it responsibly.
Is ChatGPT safe for business use?
The honest question I get from almost every business owner: 'We want to use ChatGPT, but is it actually safe?' The answer is: it depends on which plan you use and how you set it up. Using ChatGPT safely in business is absolutely possible — but not without making a few deliberate choices.
OpenAI offers several tiers. The free version and ChatGPT Plus (aimed at individuals) have different privacy settings than the business tiers. The key difference comes down to what OpenAI does with the text you type in.
What happens to your data?
This is the point most business owners don't think through carefully enough. If you use the free version or ChatGPT Plus and haven't turned off the 'Improve the model for everyone' setting, OpenAI can use your conversations to further train the model. That means what you type in — including customer data, internal documents, or strategic information — could end up in the training process.
Free and Plus: default settings carry risk
On the free and Plus tiers, model training is enabled by default. You can turn it off via Settings > Data Controls > 'Improve the model for everyone'. Once you do that, conversations are no longer used for training. But: a setting that has to be toggled is a human factor — your employees each need to do this themselves on every device they use.
ChatGPT Team and Enterprise: business contract, different rules
ChatGPT Team (available as a shared workspace for multiple users) and ChatGPT Enterprise are designed for business use. On both tiers, OpenAI does not train on your data by default. You retain control over your own conversations and can manage the workspace as an admin. Enterprise also offers SSO, extended security settings, and Data Processing Agreements (Data Processing Addendum).
For an SME with a small team, ChatGPT Team is often the most practical starting point for business use. Always check the current subscription terms at openai.com — OpenAI updates these regularly.
ChatGPT and GDPR: what you need to know
If you operate in the EU, you fall under the General Data Protection Regulation (GDPR). The question isn't only whether ChatGPT is safe, but also whether your use of it is GDPR-compliant. Those are two separate questions.
OpenAI processes data on servers that are (partly) outside the EU. That isn't prohibited in itself, but it does require a valid legal basis for the transfer — and demonstrating that is your responsibility as the data controller.
Signing a Data Processing Agreement (DPA)
If you enter personal data into ChatGPT — even indirectly, such as an email that contains a customer's name — you are required to have a Data Processing Agreement in place. OpenAI offers a Data Processing Addendum, but it is only available via ChatGPT Enterprise or through the API. For Team users: check whether and how OpenAI covers this within your subscription tier.
Legal basis for processing
Do you have a legitimate interest to enter customer data into ChatGPT? Or do you have explicit consent? Think this through in advance. In practice, the safest approach is: enter as little personal data as possible, and anonymise wherever you can.
What you should NEVER put into ChatGPT
This is the list I always share when I start working with a team. Regardless of which plan you're on, there are categories of information you should never casually paste into ChatGPT:
- Personal data of customers or employees (names, email addresses, social security numbers, financial data)
- Confidential contracts or legal documents containing sensitive clauses
- Passwords, API keys, or access credentials
- Strategic business plans that are not yet public
- Medical or health data of any individual
- Information covered by a non-disclosure agreement (NDA)
Setting up ChatGPT safely for your team
The technology is only one side of the story. The other side is your team. With SMEs I often see employees enthusiastically diving into ChatGPT without anyone ever having thought through guidelines. That is a risk.
Step 1: Choose the right plan
For business use I recommend starting with at least ChatGPT Team. That gives you a shared workspace, stronger privacy guarantees, and central admin control. Individual Plus accounts per employee are harder to manage and offer less business-grade protection.
Step 2: Write an AI usage policy
A single page is enough to give your team clear guidance: what information can and cannot be entered, which tasks ChatGPT is suitable for, and how to handle the output (always fact-check and review the tone). Tie this into your existing code of conduct or privacy policy. The EU AI Act and GDPR also require that employees working with AI have sufficient AI literacy — a clear policy helps you fulfil that obligation.
Step 3: Train your team — briefly but concretely
No all-day courses needed. In my experience, a ninety-minute session showing what ChatGPT can and can't do, where the boundaries are, and how to write good prompts already makes an immediate difference. People then know what they're doing — and what to avoid.
Alternatives as an extra safeguard
Want even more control over your data? There are alternatives where data stays within the EU or runs on-premise entirely. Think Microsoft Copilot (via an M365 licence with a business contract), the OpenAI API combined with your own application, or open-source models you self-host. The API route gives you the most flexibility and privacy control, but also requires more technical setup.
Costs: what does ChatGPT for business actually cost?
ChatGPT Plus costs around twenty euros per month per user at the time of writing. ChatGPT Team runs higher — think twenty-five to thirty euros per user per month with annual billing, depending on the number of seats. ChatGPT Enterprise has custom pricing based on volume and contract length.
For most SMEs, Team is the most practical entry point for responsible business use. For a team of five to ten people, budget a few hundred euros per month — often less than you save once the team works more efficiently with it. Check openai.com for current pricing, as it is updated regularly.
Beyond subscription costs, implementation time also counts: drafting guidelines, running a team training session, and any integration with your workflows. That doesn't have to be expensive, but it does take attention. Without that investment, you're wielding a powerful tool without knowing how to handle it safely.
Conclusion: using it safely requires a deliberate choice
Using ChatGPT safely in business is not a myth, but it takes more than creating a free account and letting your team loose. The essentials: choose the right plan (Team or Enterprise for business use), set clear guidelines, train your people, and never enter more personal data than strictly necessary.
The businesses I work with that get this right reap the benefits of faster content, better preparation, and sharper focus. Those that roll it out ad hoc sooner or later run into a privacy incident or confusing output. The difference isn't in the technology — it's in the approach.
Key takeaways
- For business ChatGPT use, start with at least the Team tier — it does not train on your data by default.
- Never enter personal data, contracts, or strategic information without thinking through your GDPR legal basis first.
- Write a short AI usage policy for your team — a single page of dos and don'ts already adds real value.
- ChatGPT Team costs around twenty-five to thirty euros per user per month — check openai.com for current pricing.
- AI literacy for employees is not just smart practice — it is also expected under the EU AI Act.
