 ## Preconfigured alerts
 
-Preconfigured alerts are regionalized alerting rules that Scaleway defines for you. They are active in all the regions where you have enabled the [alert manager](#alert-manager). You can think of them as alarm sensors. They allow you to receive alerts for behaviors that we deem abnormal on your resources. Preconfigured alerts only apply to the metrics and logs of your Scaleway resources.
+Preconfigured alerts are regionalized alerting rules provided by Scaleway for specific products. They are only available for resources that support preconfigured alerting and do not apply to all Scaleway products. These alerts help you detect behaviors considered abnormal on the supported metrics and logs of your Scaleway resources. They are enabled automatically in any region where the Scaleway [alert manager](#alert-manager) is active.
