I've configured the Catalog Permissions on my categories, however, "guest/not logged in" users are still able to see my categories.
I imagine if I don't select "NOT LOGGED IN" for the category permission, it shouldn't show to Guest Users, right?  


In the Catalog Permissions, when you click into a customer group, it means that customer group cannot see the catalogue.  

If you don't select "NOT LOGGED IN" for the category permission (, it should show to Guest Users. 

For more product information, please refer our Magento 2 Catalog Permission page and our User Guide.
