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.
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 in ChatGPT Enterprise
Sensitive data in prompts even though training-use is excluded
Custom GPT misconfiguration exposing organizational data
Shadow consumer-tier ChatGPT in parallel with enterprise rollout
Plug-in and connector risk in custom GPTs
Vendor concentration risk for organizations standardizing on OpenAI
Recommended controls
Deploy ChatGPT Enterprise with SAML SSO and provision through identity provider
Block consumer ChatGPT at network and DLP layer to force enterprise-tier use
Govern custom GPTs with workspace-level review and approval
DLP on prompts where sensitive data classification is realistic
Audit prompt and output logs at appropriate retention
