What is a VPN and how does it work?
A VPN, or Virtual Private Network, is a technology that creates a secure and encrypted connection over a less secure network, like the internet. It allows users to send data securely as if they were directly connected to a private network. The data is encapsulated in a VPN tunnel, which protects it from eavesdroppers and ensures privacy.
When you connect to the internet through a VPN, your traffic is routed through a VPN server. This server can be located anywhere in the world, making it appear as though your internet connection is coming from that location. This helps in masking your actual IP address, enhancing your online privacy and allowing access to content that may be restricted in your region.
Do I need a VPN if I have a secure home WiFi network?
Even if your home WiFi network is secure, using a VPN can provide additional layers of protection.
