What is a VPN and how does it work?
A VPN, or Virtual Private Network, is a technology that creates a secure, encrypted connection between your device and a remote server operated by a VPN service. When you connect to a VPN, your internet traffic is routed through this secure server, masking your IP address and encrypting the data being sent and received. This process helps protect your online activities from hackers, particularly when you are using public Wi-Fi networks.
By encrypting your internet connection, a VPN ensures that any sensitive data, like passwords or credit card information, is not exposed to potential eavesdroppers. This makes it significantly more difficult for anyone on the same public network to intercept your data or monitor your online activities.
