VPN, Virtual Private Network is a group of computers attached together with the help of a public network, the internet. VPN is used to secure your computer’s connection so that the exchange of data happens safely just between the intended computers.

Depending upon the type of your work, there are different VPNs to suit the requirement. While L2TP, PPTP, and IPSec are well-known, there are some differences between them.
