SonicOS does not create any default website objects. You can create the objects based on requirements and group them into a single group to use in policies.
From the Websites page, you can:
Filter the table data
Add, modify, and delete website objects and groups
Clone from an exiting group to create a new group
Export the table information into CSV file
Refresh and sort the table columns data to identify the specific results
Customize columns to show or hide the table columns, and save the filter preferences for next time log in
View the list of policies where the web category group is used.
