What does Full Tunnel VPN do?

The Full Tunnel VPN option routes and encrypts all network requests through the VPN, meaning that regardless of their destination, all data traffic from the user's device is sent through the VPN connection. This process ensures that sensitive information is kept secure and private, as it is encrypted and less vulnerable to interception.

When using a Full Tunnel VPN, users can benefit from the security of having all their internet traffic go through the VPN server, including web browsing, streaming, and any other online activity. This holistic approach offers complete protection against threats and potential eavesdropping as the traffic is cloaked in encryption.

In contrast, the other options describe different networking behaviors. Allowing all traffic to access the internet directly would mean losing potential security benefits provided by the VPN. Routing only specific traffic through a VPN refers to Split Tunnel VPNs, which send some traffic through the VPN and the rest directly to the internet. The notion of being used primarily for secure email communications is too narrow, as a Full Tunnel VPN serves a broader purpose by securing all types of traffic, not just emails.
