VPN stands for Virtual Private Network, which means a virtual private network. In simple terms, VPN creates a secure channel between your device and the internet. All traffic goes through an intermediary server in an encrypted form. The main idea is that your internet service provider and third-party observers only see an encrypted stream of data. They do not know which sites you visit and what data you send. Basic Principle of VPN Operation When you connect to a VPN, your device establishes a connection with the VPN server. This server can be located in another country or city. Next, all your traffic passes through this server. Websites and services see not your real IP address, but the IP address of the VPN server. Therefore, the feeling is created that you are in another part of the world. At the same time, data is encrypted. Even if someone intercepts the packets, they will not be able to read their contents without the encryption key.
