ChatGPT Enterprise Security

Customer prompts and outputs are not used to train OpenAI models. That is the headline security guarantee. Verify it. Then secure everything around it.

What it is

ChatGPT Enterprise is OpenAI's enterprise tier of ChatGPT. Includes SAML SSO, admin console, advanced data analysis, custom GPTs at the workspace level, and contractual data-handling guarantees. Underlying models are the latest GPT family.

Central risk

The central risk

Data handling and the layer of trust the enterprise tier creates. The contract says customer data is not used to train OpenAI models. That guarantee removes one risk class. Other risks remain: prompts containing sensitive data are still flowing to OpenAI infrastructure, custom GPTs can be misconfigured, and shadow-IT consumer ChatGPT use undermines the enterprise contract.

Specific risks
