# Third-party Linux security applications

| Application Name | Limitations                                                                                                                                                                                                                                                                           |
| ---------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| SELinux          | Because SELinux collides with the agent injection mechanism, injection-based security modules (ROP Mitigation and Brute Force Protection) are disabled when SELinux is enabled. All other exploit and malware protection functionality works as expected. No user action is required. |
| Symantec         | Running Symantec Kernel Module on Linux machines side by side with Cortex XDR is not supported.                                                                                                                                                                                       |
| McAfee           | Running McAfee Kernel Module on Linux machines side by side with Cortex XDR will lead to the Cortex XDR agent running without the Kernel Module and be partially protected. It is recommended to have the McAfee KM disabled.                                                         |

# 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/compatibility-matrix/cortex-xdr-agent-compatibility-with-third-party-security-products/third-party-linux-security-applications.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.
