WPDistrib Comments
This free online tool lets users quickly test header security.
By default, WordPress does not apply any protection in this area.
This is why the extension Headers Security Advanced & HSTS WP, included in the WPDistrib starter, automatically handles this configuration.
No manual action is required: the extension writes the necessary directives into the .htaccess file, with no technical setup.
Running a test on SecurityHeaders.com is simply a way to confirm that everything is correctly set up.
