# MSSP multi-tenant

Cortex XDR supports pairing multiple Cortex XDR environments with a single main account enabling MSSPs to easily manage security on behalf of their clients.

The following license options are available for MSSP multi-tenants:

| Option                       | Description                                                                                                                                                                                                                                                                                                                                                                                       |

| Central licensing management | The MSSP acquires a license for the main tenant (parent account) with resource allocations of total endpoints and/or GB for child tenants. From the main tenant, the administrator can then dynamically create child tenants and allocate the resources among its child tenants. All child tenants are automatically paired to the main tenant and the licenses are all owned by the main tenant. |
| Customer-owned license       | The MSSP acquires a license for its parent tenant. All end customers must acquire their own licenses in a separate contract. The child tenants must be manually paired to the main tenant.                                                                                                                                                                                                        |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/cortex-xdr-3.x/cortex-xdr-3.x-documentation/multi-tenant/what-is-cortex-xdr-multi-tenant/mssp-multi-tenant.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
