What is a VPN?
A VPN, or Virtual Private Network, establishes a secure connection over a less secure network such as the Internet. This tool not only helps in protecting your online activity but also shields your data by encrypting it, making it unreadable to anyone who might intercept it. Imagine sending a postcard (your data) through a crowded post office (the Internet). Just like anyone can read a postcard, cybercriminals can easily access your unprotected data. A VPN acts like a sealed envelope that securely transports your message.
How VPNs Work
VPNs function by creating a private tunnel between your device and the internet. When you activate a VPN, your device connects to a server run by the VPN provider. This server acts as an intermediary between you and the websites you want to reach. Essentially, when you send or receive data, it first goes through the secure tunnel to the VPN server and then to the intended destination.
A key aspect here is encryption; data is scrambled before it enters the tunnel, protecting it from prying eyes. Moreover, your IP address is masked, effectively making it seem like your online activities are originating from the VPN server's location instead of your own. This means you can circumvent geographical restrictions, which is beneficial for accessing region-locked content.
Common VPN Protocols
