A VPN (Virtual Private Network) encrypts your internet connection and hides your real IP address. All your traffic routes through a VPN server, so websites see that server’s IP instead of yours.
How a VPN Works
- You install a VPN app and connect to a server
- Your device and the VPN server create an encrypted tunnel
- All internet traffic travels through that tunnel
- Websites see the VPN server’s IP, not your real one
What a VPN Protects You From
- ISP snooping — your provider cannot see which sites you visit
- Public Wi-Fi attacks — encrypted traffic cannot be intercepted
- IP-based tracking — advertisers see the VPN’s IP, not yours
What a VPN Does NOT Protect You From
- Browser cookies and fingerprinting
- Malware or viruses
- Logging by the VPN provider itself
