VPNs use a few methods to make this anonymous data security work:
Encryption scrambles your data in a format so that only your recipient can read it
Tunneling protocols are then used to create encryption “tunnels” within your Wi-Fi or cellular network. Tuneling provides protection by isolating and concealing your data from the rest of the users on the network. All networks – secure or unsecure – are more private because of tunneling.
Remote servers act as the destination for your encrypted data tunnel. Your data gets shipped out to VPN servers in other countries to ensure your identity remains secret.
Split tunneling allows you to decide which of your data is sent through the VPN and which is sent directly to its destination. This helps you stay secure while using public Wi–Fi networks and allows you to access geo–restricted content in other countries. Kill switch technology automatically disconnects your
