What role does the Firebox’s VPN feature play in remote access?

The Firebox's VPN feature plays a crucial role in enabling secure communications for remote users who need to access the internal network over the internet. By using a Virtual Private Network (VPN), the Firebox encrypts the data transmitted between the remote user's device and the internal network, ensuring that sensitive information remains confidential even when accessed over public or less secure internet connections. This secure connection not only protects the data in transit from interception but also provides authenticated access to network resources as if the user were directly connected to the internal network, allowing for a seamless work experience regardless of the user's physical location.

The other choices do not accurately describe the primary function of the VPN. Disconnecting users from the internal network does not align with the purpose of a VPN, which is to establish connections, not sever them. Restricting access to specific files is more about data access control rather than the VPN's purpose of secure connectivity. Providing free public Wi-Fi access is unrelated, as the VPN feature is focused on secure connections rather than offering free internet services.
