A VPN (Virtual Private Network) is a service that encrypts a user's internet connection and routes it through a server in another location, allowing the user to access the internet anonymously and securely. VPNs are often used to protect the privacy and security of internet users, especially when accessing the internet via public WiFi networks or when using the internet in countries with strict internet censorship laws.
When a user connects to a VPN, their internet traffic is routed through an encrypted tunnel to a server in another location. This makes it difficult for others to intercept or monitor the user's internet activity because the traffic is encrypted and looks like it is coming from the VPN server and not from the user's device itself.
VPNs are often used by individuals to protect their online privacy, but also by businesses to secure their networks and protect sensitive data. There are many different VPN providers, each with their own unique features and pricing plans.
