This CAST AI feature informs you via UI or webhook about key issues affecting the cluster. Secondly, this interface is used to pass other valuable information, such as the daily vulnerability report. This guide outlines the notification types you may see in CAST AI with relevant action points.

Once new items are ready for your view, the bell icon in the top menu will show a mark. You’ll be able to view all items in the Notifications center.

Due to the dynamic nature of Kubernetes clusters, notifications are set to expire automatically in 24 hours.
