VPN Basics: How It Works
A VPN (Virtual Private Network) creates an encrypted tunnel between your device and the internet, protecting your data and hiding your real IP address.
What Does a VPN Do?
A VPN encrypts your internet traffic so no one can see what you're doing online. It also masks your real IP address, making it appear as if you're browsing from a different location.
How VPN Encryption Works
When you connect to a VPN, your data is encrypted before leaving your device. It travels through a secure tunnel to the VPN server, where it's decrypted and sent to its destination. Return traffic follows the same path in reverse.
Why Use a VPN?
VPNs protect you on public WiFi, prevent ISP tracking, bypass geo-restrictions, and add a layer of privacy to your online activities. They're essential tools for digital privacy.
VPN Limitations
VPNs don't make you completely anonymous. They can't protect you from malware, phishing, or tracking cookies. You still need good security practices alongside your VPN.
