Overview
This option allows you to remain connected to our servers when your device goes to sleep. Normally if your device enters Sleep mode, the VPN can become disconnected and expose your actual location. This can be useful if your device is behind a firewall or NAT (Network Address Translation).
This adds an additional layer of security to the VPN, by preventing any unwanted (private) information from leaking across your regular (public) network without your knowledge/permission.
Windows
This setting is disabled by default, you must enable it yourself. However, enabling this setting may impact battery life. If used in combination with the Connect Automatically option, VirtualShield will remain connected to our secure network at all times.
