A virtual private network (VPN) is an encrypted connection to the Internet that adds an extra layer of privacy and security to your online activities. It's the equivalent of installing frosted mirrored glass throughout your glass house, allowing you to see the outside but no one can see the inside. When you use a VPN, your data is sent through an encrypted tunnel to the VPN servers and nobody, not even your ISP or the government, can access it. This private Internet access also protects your online identity as the device's real IP address is hidden by the VPN server's IP address. This way, you can safely use the Internet anywhere in the world, even on public Wi-Fi networks.
