ChatGPT Enterprise Security

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

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

• 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
• Vendor due-diligence: review most recent SOC 2 attestation

Posture Check checkpoint

Vendor due-diligence (Q26–Q30) is the central control. Data classification (Q6–Q10) determines what's safe to prompt with.
