This VPN can also allow you to access personal information so that it is safer to access the internet such as browsing, surfing and other activities. Why is that?

This is all, VPN will also use existing tunneling technologies such as PPTP, L2TP and IPSec or also called Internet Protocol Security. In addition, this VPN is also a combination of tunneling technology and encryption so that it can be used more safely than most internet network connections.
In connecting this VPN on 1 PC with another, VPN also requires a server that is named a VPN Server. Where this server is in the form of a computer with a VPN server application so that both will be able to contact each other. In addition, this VPN Server will also verify the username and password and if successful, the VPN Server will also provide a new IP Address on the Client computer device so that a connection or tunnel will be formed.
