A VPN (Virtual Private Network) can be described as a safe connection to the internet. Instead of connecting to the internet directly and allowing anyone to see your real IP address, a VPN lets you send and receive data through a secure tunnel between your device and the internet. Nobody outside this tunnel can see what you’re doing online or figure out what your real IP address is.

People commonly use a VPN to avoid internet snooping, circumvent geographic restrictions, bypass nation-wide firewalls, access blocked websites, and browse the internet without leaving a trace. Corporations sometimes use a VPN to securely connect individual branches and allow employees to work remotely from anywhere in the world.

Virtual Private Networks, or VPNs for short, make it possible to access a private network and transfer data remotely through public internet. Originally, VPNs were popular mainly with large corporations, which used them to transfer data to and from remote locations. Nowadays, VPNs have become very popular among regular internet users, who use them to improve their online privacy and security.

VPNs are sometimes called tunnels because they create a private pathway through the internet for data to pass through. Typically, all data that passes through a VPN tunnel is encrypted and thus impossible to analyze or steal. What’s more, a VPN hides the real IP address of anyone who uses it.
