A Virtual Private Network (VPN) is a service that creates a secure, encrypted connection between your device and the internet. When you connect to a VPN, your internet traffic is routed through a VPN server, helping protect your data on public and private networks while masking your public IP address.
A VPN can help protect your privacy by preventing others from easily viewing your internet traffic and by making your connection appear to come from the VPN server rather than your own IP address. This makes VPNs particularly useful when using public Wi-Fi, traveling, or accessing your home network remotely.
