Privacy & VPN 6 min readBy DigiMetrics Hub TeamPublished
What Is a VPN and Do You Really Need It?
A VPN encrypts your internet traffic and hides your IP. Learn how VPNs work, what they protect against, and when you actually need one.
A VPN — Virtual Private Network — creates a secure encrypted tunnel between your device and a remote server. Anything you do online appears to come from the VPN server, not your real connection.
How a VPN Works
- You install a VPN app and connect to a server.
- Your traffic is encrypted before it leaves your device.
- The VPN server forwards your requests using its IP.
- Websites see the VPN's IP, not yours.
Check your IP, then connect to a VPN to see it change.

Do You Need One?
