Trusted domains window

This list contains the domain names and domain name masks that will be excluded from encrypted connection scans.

Example: *example.com. For example, *example.com/* is incorrect because a domain address, not a web page, needs to be specified.

By default, the list is empty.

You can add, edit and remove domains from the list of trusted domains.

Clicking the Delete button removes the selected item from the table.

This button is available if at least one item is selected in the table.

The selected element's settings are changed in a separate window.
