- After you enable alert and incident collection in the Defender XDR data connector, Defender XDR incidents appear in the Microsoft Sentinel incidents queue shortly after they're generated in Defender XDR. It can take up to 10 minutes from the time an incident is generated in Defender XDR to the time it appears in Microsoft Sentinel. In these incidents, the **Alert product name** field contains **Microsoft Defender XDR** or one of the component Defender services' names.

- When the Defender XDR connector is enabled, alerts created by Defender XDR-integrated products are sent to Defender XDR and grouped into incidents. Both the alerts and the incidents flow to Microsoft Sentinel through the Defender XDR connector. If you enabled any of the individual component connectors beforehand, they appear to remain connected, though no data flows through them.

The exception to this process is Microsoft Defender for Cloud.

- Microsoft Sentinel's incident creation rules allowed you to filter the alerts that would be used to create incidents. With these rules disabled, you can preserve the alert filtering capability by configuring [alert tuning in the Microsoft Defender portal](/microsoft-365/security/defender/investigate-alerts), or by using [automation rules](automate-incident-handling-with-automation-rules.md#incident-suppression) to suppress (close) incidents you don't want.

- You can no longer predetermine the titles of incidents, since the Defender XDR correlation engine presides over incident creation and automatically names the incidents it creates. This change is liable to affect any automation rules you created that use the incident name as a condition. To avoid this pitfall, use criteria other than the incident name as conditions for [triggering automation rules](automate-incident-handling-with-automation-rules.md#conditions). We recommend using *tags*.
