What is a VPN?

VPN (Virtual Private Network) is a secure communication channel between your computer and a server that encrypts any data passing through it.

VPN works thanks to its components:

• Security protocols + encryption - protection of any data passing through the server, by creating a secure connection and affecting the type of data encryption.
  

• Server - when using VPN, your data is first sent to the VPN server, and afterwards - to the resource you are requesting. This means that the request sent by you hits the server of the resource, but your data (information) can only be moved between your device and the VPN server, which also passes through a secure communication channel, so that the server you are requesting cannot receive any information about you.
  

When connecting to a VPN, your ISP can only track encrypted traffic coming to the VPN server, but it cannot decrypt the data itself or track the websites you visit.

Most often, VPN is used to protect confidential information (electronic correspondence, online banking) and for viewing blocked sites from anywhere. VPN is also used to hide your real location by changing your IP address, which changes depending on which server you are connected to.
