Alert View

The Alert View screen displays alerts triggered by detection models and allows you to further investigate each alert.

You can investigate alerts through an in-depth root cause and impact analysis, which helps you understand the extent and severity of any alert and further determine actions to respond to the alerts.

The following table outlines the actions available on the Alert View screen.
