Is ChatGPT safe for business?

What happens to what employees type into ChatGPT?

That depends on the account. On a personal plan, OpenAI's consumer terms apply. In a Business (formerly Team) or Enterprise workspace, your company sets the rules and OpenAI is your processor.

The table compares ChatGPT's own plans. seef is another option: an environment of your company's own, hosted in the EU. The last section says when seef fits.

Is ChatGPT Plus or Pro safer than the free version?

Not for company data. Go, Plus and Pro raise your limits but keep the consumer terms: training is on by default and there is no DPA.

If someone uses a personal account for work anyway, keep it to material without personal or confidential data. Turn off Improve the model for everyone under Settings, Data controls, and skip the thumbs up or down, because feedback can send the whole conversation to training. A temporary chat stays out of training and is deleted within 30 days, but it does not make forbidden input acceptable.

Is ChatGPT Business GDPR compliant?

No tool is compliant on its own, because GDPR judges what you do with personal data. A business plan gives you the contract you need: a DPA in which OpenAI is your processor, as Article 28 GDPR requires.

On a free or Plus account there is no DPA, and OpenAI is the controller of what staff enter. Customer data pasted in goes to a third party, and you have to justify that disclosure yourself.

You still need a lawful basis, an entry in your record of processing activities and a risk assessment, sometimes a DPIA (Article 35). Health data needs an Article 9 exception, and OpenAI's standard DPA says no sensitive data is meant to be transferred.

Is it a data breach when staff paste personal data into ChatGPT?

Often, yes. The Dutch regulator, the Autoriteit Persoonsgegevens, reported in August 2024 several such breaches, including a GP practice employee who entered patients' medical data into a chatbot against the rules.

Its line is clear. Chatbot use against company rules with personal data is a breach; use as company policy is not a breach, but often not lawful either. In 2025 the municipality of Eindhoven reported a breach after staff uploaded files with personal data of residents and employees to public AI websites.

A reportable breach goes to the regulator within 72 hours (Article 33 GDPR). You record every breach and assess whether to tell the people affected.

Where is ChatGPT data stored and processed?

In the EEA and Switzerland your contract is with OpenAI Ireland, but the DPA allows transfers outside the EEA under standard contractual clauses or an adequacy decision. OpenAI is a US company, and in 2025 a US court made it keep consumer and Team (now Business) chats, deleted ones included, until September.

Enterprise lets new customers store data in Europe and, if eligible, run the model there, though apps, web search and some processing steps can still go elsewhere. Business is rolling out a storage region that does not cover where the model runs, and copies of prompts and responses stay in the US for abuse monitoring.

What risks remain on a Business or Enterprise plan?

A business plan settles the contract and training. These risks stay:

• People paste in more than the task needs. A DPA does not make that proportionate.
• Answers can be wrong in a convincing way. Check them against the source before you use them.
• Connectors follow existing permissions, so an overshared folder becomes searchable. Apps and GPT actions send input to outside services, under their terms.
• Hidden instructions in a document, email or web page can steer ChatGPT into sharing data (prompt injection).
• Business keeps the chats and files of removed members indefinitely.

What should a company do this week?

Start with the tool and the data. A full AI policy and a check for unapproved tools come after.

• Choose one work tool, such as ChatGPT Business or seef. Customer and employee data stay out of personal accounts.
• Sign the DPA, record the processing and check that your privacy notice covers it.
• List what never goes in: national ID numbers, medical data, full customer files, passwords.
• Check customer contracts and NDAs before anyone uploads a customer's documents.
• Ask your provider which retention settings you get, and enable only the connectors you need.
• Name who assesses, records and, where required, reports a breach within 72 hours.
• Train your team: the AI Act, as amended in 2026, requires measures that support staff AI literacy.

When is ChatGPT Business or Enterprise enough, and when does seef fit?

For everyday drafting and summarising, ChatGPT Business with a DPA and clear rules is enough for many companies, and it is self-serve, usually from two users. Enterprise is the plan for storage and model processing in Europe, and Microsoft 365 users should compare Copilot.

seef fits when you want your team's AI use off personal accounts and onto company documents, with a clear boundary around what AI can reach. Your company gets its own isolated environment, hosted in the EU and run by seef, with nothing for you to host or patch. You fill a knowledge base from SharePoint or Google Drive, and it holds only what you put in. People sign in with their Microsoft 365 or Google Workspace account, and answers show the documents they came from.

You choose the models with us, including models hosted in the EU. Processing only in the EU or hosting on your own servers is possible on request, and the data processing agreement records what we agree. seef is a service of Timformatie, certified to ISO 27001:2022 and NEN 7510-1:2024. The security page describes the standard setup, and the European alternatives guide compares other options.
