Navigating the Security Insights application
The Security Insights application is based on tabs that contain different widgets. Overview and Threats are the main application areas, then you have specific tabs where you can monitor different network security aspects.
Every widget in each of the tabs includes an information icon explaining the data it displays plus a list of operations you can perform on the graph when possible. Besides, some of them include options to maximize the widget and go to the query that contains the represented data.
You can save a screen capture of all the widgets in a tab selecting the icon at the top right corner. As explained in the Security Alerts article, you can click the lighting icon to define alert chains, which are alerts built upon two or more already existing alerts.
The following articles describe the widgets that you can see in each of the tabs. For additional information and actions you can perform on each widget, see the in-app help of each widget selecting the corresponding information icon.
