The phone remains on. This could result in a major security breach, especially on a wifi-hotspot. Does this suggest the phone has already been hacked? Why is it doing that and how do I prevent this?

The iPhone does not have a built-in VPN. You still have to have a VPN service that you've signed up for and then once configured you can use the VPN switch in the settings to turn on the service.
Please start a new post and provide more details on both the issue and your iPhone. For example, which exact VPN service are you using and what is the exact model of your iPhone and the version of iOS that it is running?
