# Domain separation

Domain separation in Telecommunications Network Inventory provides a structured and efficient way to manage complex, multilevel organizational environments. It enables secure, tailored access and control, ensuring that users view data relevant to their domain.

## Support level: Basic

-   Business logic: Ensure that data goes into the proper domain for the application’s service provider use cases.
-   The application supports domain separation at run time. The domain separation includes separation from the user interface, cache keys, reporting, roll-ups, and aggregations.
-   The owner of the instance must set up the application to function across multiple tenants.

For more information on support levels, see [Application support for domain separation](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/platform-security/domain-separated-apps.md)
