A VPN tunnel is a secure connection that carries data between two devices or networks over the internet. It protects the data while it travels across a public network.

The tunnel creates a private path between the connected devices. VPNs use encryption to prevent other people from easily reading the data moving through the connection.

How It Works

• A VPN client connects to a VPN server.
• The VPN creates a secure tunnel between them.
• Data is encrypted before it enters the tunnel.
• The encrypted data travels across the internet.
• The receiving end decrypts the data and delivers it to its destination.

Common Uses

• Securely connecting to an office network from home.
• Connecting two business networks over the internet.
• Protecting data when using public Wi-Fi.
• Allowing remote workers to access private network resources.
• Connecting users to private cloud or business services.
