This means it's scrambled into an unreadable mess for anyone trying to intercept it. And to add an extra layer of ninja-like stealth, the VPN creates a tunnel between your device and the server, making it nearly impossible for anyone to sneak a peek at your sensitive information. Consider it your digital fortress, protecting you from the prying eyes of the internet.

Some are faster, while others prioritize security. It's like choosing between speed and safety when driving a sports car (but without the fun). Popular VPN protocols include OpenVPN, IPSec, and L2TP/IPSec. Each has its own strengths and weaknesses, so it's up to you to decide which one fits your needs like a cozy winter sweater.
