There are two basic sections to this. The Slider for the Identity lock and the Go To ZoneAlarm Identity Protection Center button. The button will open a browser page and take you to a website. I will not go into that here, because it can change at a moments notice, and the help for that site will be done thru that page. But back to the slider. High Prevents the contents of myVAULT from being sent to unauthorized destinations, and it will not even ask you about it. Medium will block the information but ask if you want to transmit it. Off ignores the info in myVAULT.
