Full Tunnel VPNs are designed to route all traffic from a connected device through the VPN tunnel, regardless of the intended destination. This means that once a device establishes a full tunnel VPN connection, all outgoing traffic, including web browsing, email, and application data, gets encrypted and sent through the VPN server. This approach enhances privacy and security, particularly when accessing the internet on unsecured networks, as it prevents potential eavesdroppers from intercepting the data.

The key aspect of Full Tunnel VPNs is that they create a secure connection to the VPN server, which acts as a gateway to the internet. Users benefit from increased anonymity and protection from local network threats. Additionally, since all traffic is funneled through the tunnel, organizations can enforce security policies or monitor and control data leaving their network.

In contrast, Split Tunnel VPNs only route traffic destined for specific, secured networks through the VPN, allowing other traffic to go directly to its destination without encryption. Understanding this distinction clarifies why the assertion about Full Tunnel VPNs is true.
