What is a VPN and How Does it Work?

A Virtual Private Network, or VPN, is a technology that creates a secure and encrypted connection between two or more devices over the internet. The primary purpose of VPN gratuit avis is to protect the user’s privacy and data security by encrypting internet traffic and masking the user’s IP address, making it difficult for hackers, ISPs, and governments to monitor or track their online activity.

When a user connects to a VPN server, the device first establishes a secure and encrypted connection to the VPN server. The VPN server then acts as a middleman between the user’s device and the internet, routing all internet traffic through the encrypted connection. This makes it difficult for anyone to intercept or access the user’s internet traffic, even if they are on the same network or using the same Wi-Fi hotspot.
