# Where can I install the Cortex XDR agent?

The Cortex XDR agent is installed on supported physical and virtual endpoints.

Cortex XDR agent is a software component of the larger Cortex products. It provides both cloud workload and endpoint protection, depending on your license and deployment environment. Cortex XDR agent is installed on supported physical and virtual endpoints. As a comprehensive security solution, it secures a wide range of assets, from cloud environments (like containers and Kubernetes clusters) to traditional endpoints, and mobile devices. To ensure maximum protection of your endpoints, Palo Alto Networks recommends that you always deploy the latest maintenance version for each agent release.

Palo Alto Networks strives to support the latest major operating systems. When a new operating system is available, there may be a short delay in our support as we test interoperability.

Until a Cortex XDR agent release reaches its end-of-life status, the following support is provided:

* Microsoft operating systems are supported for three years beyond the end of Microsoft support.
* In general, other operating systems are supported until they reach end-of-life, or their extended life, as relevant.
* For Android, we support the latest Cortex XDR agent app that is available on the Google Play Store regardless of the app release date. An agent version that is no longer on Google Play will be supported for one year after the date of its release.

#### Agent releases

To ensure maximum protection of your endpoints, Palo Alto Networks recommends that you always deploy the latest maintenance version for each agent release.

Critical Environment (CE) versions must be enabled in your Cortex system before use. CE versions are designed for sensitive and highly regulated environments. These versions receive full content update coverage and contain the same feature set as the standard line it is based on. Please note, that some bug fixes, introducing higher stability risk, may not be incorporated into the maintenance releases of these lines. Support is provided for CE versions for 24 months, while support for standard versions is provided for 9 months.

See [Cortex XDR Agent Releases](https://docs-cortex.paloaltonetworks.com/r/Cortex-XDR/Cortex-XDR-Agent-Releases/Cortex-XDR-Agent-Releases) for details and the release notes of the current agent versions. EOL versions may be shown in this document for information purposes only.

## 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/where-can-i-install-the-cortex-xdr-agent.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.
