A Virtual Private Network (VPN) is a secure, encrypted tunnel between your device and the internet. It hides your IP address, encrypts your traffic, and lets you browse privately and freely.
When you connect to a VPN, your device creates an encrypted tunnel to a VPN server. All your internet traffic flows through this tunnel, so websites see the VPN server's IP instead of yours. Your ISP can only see encrypted data — not what you're browsing.
VPNs are legal in most countries and widely used by individuals, businesses, and governments. Some countries with restrictive internet policies may regulate or ban VPN use. Always check your local laws when traveling.
