What is a VPN and how does it work?

A VPN helps safeguard your privacy online by encoding your internet traffic and ensuring secure connectivity. When you use a VPN, your data is routed through a remote server, hiding your IP address and making your online activities anonymous. This offers protection for your sensitive data, shielding it from cybercriminals, online monitors, and your ISP. VPNs are especially useful when using public Wi-Fi, accessing geo-restricted content, or maintaining privacy while browsing. They create a secure “tunnel” between your device and the internet, ensuring that sensitive data like passwords, banking details, and communications remain private. Whether for work, streaming, or general security, understanding how a VPN works is key to staying safe in the digital world.
