What is VPN? - Everything you wants to know

When you uses an internet connection, you are being connected to a public or shared network through internet service provider (ISP). This means that any information you send or receive through internet is just that public. Because your ISP can see what information you’re accessing, they can control the content you have access to, by blocking and censoring websites.
Not only ISP anyone with tools and knowledge including hackers, government and business can track your online activity like what you are doing, when you do it and from where you do it.

VPN Protocols

There are numbers of protocols and available security features continue to grow with time. The most common are:

  1. PPTP - PPTP is very easy to setup on every major operating system. It tunnels a point to point connection. Unfortunately, the security of the PPTP protocol has been called into question in recent years. It is still strong, but not the most secure.
  2. L2TP/IPsec  - L2TP over IPsec is more secure than PPTP and offers more features. It is a way of implementing two protocols together in order to gain the best features of each. In this case, the L2TP protocol is used to create a tunnel and IPsec provides a secure channel. This makes for an impressively secure package.
