# Cortex XDR Agent App for iOS Requirements

The Cortex XDR Agent app for iOS has the following requirements.

| Requirement               | Specification                                                                                                                                                                                                                                                                                                                                                                        |
| ------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| Operating system versions | This version of Cortex XDR Agent requires iOS 16.0 or later on the mobile device. In general, to determine the minimum Cortex XDR release for a specific operating system, refer to the The Palo Alto Networks Compatibility Matrix.                                                                                                                                                 |
| Device permissions        | <p>Device permissions are required for correct operation of the Cortex XDR Agent app.</p><ul><li>Notifications</li><li><p>Location</p><p>(only mandatory for stationary iOS-based devices mapped to a policy that raises events when a device is moved from its designated location)</p></li><li>Background App Refresh (enabled by default. May be off in low power mode)</li></ul> |
| Enable Extensions         | <p>These extensions can be enabled during onboarding. They are optional, and the user controls whether to use them:</p><ul><li>SMS/Call reporting</li><li>Call blocking and identification</li><li>SMS filtering</li></ul>                                                                                                                                                           |
| Cortex XDR widget         | When the Network Shield module is not used, use the Cortex XDR widget on the device, to ensure correct app behaviors.                                                                                                                                                                                                                                                                |

If any of the required permissions on the iOS device are turned off, Cortex XDR shows Partially Protected on the Home screen.

## 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-agent-ios-guide/8.8/get-started/cortex-xdr-agent-app-for-ios-requirements.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.
