VPN Tunnel is an encrypted pathway that carries your data across the internet as if you were on a private network. It wraps each packet in a secure layer, hides it from snooping, and sends it to a trusted server that unwraps it on the other side. This keeps your traffic safe on public Wi-Fi and lets remote workers reach company systems securely. For example, when you connect your laptop to the office network from home, a VPN tunnel protects the connection end to end.
