What is a VPN

VPN stands for "Virtual Private Network". VPN makes a secure tunnel by creating a private network from your public internet connection. In simple words, when you connect to the VPN, your internet connection is masked and your identity and data which you send and receive online become encrypted, secure, private, and anonymous. It also protects you while you are using public Wifis.

In fact, VPN is something that has become necessary. For instance, there are so many opportunists sitting online to harm you at any opportunity that they get. Thus, it offers you some serious benefits while you move around in the online world.


VPN has some additional great benefits other than securing your connection and identity. One of them is that VPN unblocks geo-restricted services on your PC, smartphone, tablet, smart TV, or other similar devices. You can perform P2P file sharing and torrenting with one of the best VPN services.

How does a VPN work

Below are the steps to give you a better idea and knowledge about how a VPN works

  1. You are connected to your ISP (internet service provider's) connection on your PC, smartphone, smart TV, or any other device.
  2. You connect to the VPN on that device. So the connected VPN server applies encryption to your connection and all the data which you transmit online whether you send or receive becomes encrypted, private, and secure.
  3. This security layer is also called a "tunnel" which means that VPN creates a secure tunnel over your internet connection and therefore, all the data which you send and receive, download and upload passes through the VPN's secure tunnel.
  4. To prevent data loss during transmission, an encapsulation process is done which is like creating an outside packet layer. It secures the data so that it reaches the destination without any loss.
  5. Once reached the destination, a decryption process is applied and the outer packet is being eliminated.
