A VPN, or virtual private network, is a service that creates a secure and private connection between your computer and a remote server owned by a VPN provider. This connection is virtual because no physical cables are involved in the connection process, and private because no one else can see your data or browsing activity. When you use a VPN, it encrypts all of your data from the moment it leaves your device, and your information passes through a safe intermediate stage, known as a VPN server. This server can hide your private information and pretend that you are logging on from elsewhere globally, which allows you to access geo-locked services.

VPNs are used for several purposes, including bypassing Internet censorship such as geoblocking, protecting communications against data profiling, and evading Internet censorship or geo-blocking. VPNs can also be used to protect your online privacy and security, as they hide your IP address and encrypt your data, making it difficult for hackers or other third-party entities to intercept your data.

When choosing a VPN service, it is important to consider factors such as the providers server hardware, first-party DNS servers, kill switch, and logging policies. Some VPN providers offer additional features such as threat protection to keep your devices safe from common internet hazards.
