# OpenAI launches Sites for Enterprise with regional data residency

Enterprise users can build team apps with databases, authentication, and US or EU data residency in eligible workspaces.

- Workspace custom domains allow publishing on verified organizational subdomains
- Private tunnels connect hosted Sites directly to approved internal APIs and infrastructure
- Supports scheduled updates and team data integration using Plugins

## Why it matters

Enterprise teams can now deploy secure, authenticated internal applications connected to private infrastructure without leaving ChatGPT's hosted environment.
