# Exclude an alert

{% hint style="info" %}

### Notice

This functionality requires a Cortex XDR Pro license.
{% endhint %}

During the process of triaging and investigating alerts, you might determine that an alert does not indicate threat. You can choose to exclude the alert, which hides the alert, excludes it from incidents, and excludes it from search query results.

You can also set up alert exclusion rules that automatically exclude alerts that match certain criteria. For more information, see [Alert exclusions](/cortex-xdr-3.x/cortex-xdr-3.x-documentation/endpoint-security/install-and-manage-endpoints/set-up-endpoint-protection/set-up-endpoint-profiles-and-exception-rules/set-up-exception-profiles-and-rules/alert-exclusions.md).

{% hint style="info" %}

### Note

Cortex XDR supports exclusion of up-to 100,000 alerts.
{% endhint %}

How to exclude an alert

1. From the **Alerts** page, locate the alert you want to exclude.
2. Right-click the row, and select Manage Alert → **Exclude Alert**.

   A notification displays indicating the exclusion is in progress.

## 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/investigate-and-respond-to-incidents/investigate-alerts/triage-and-investigate-alerts/exclude-an-alert.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.
