Which of the following best describes the function of a VPN?

A VPN, or Virtual Private Network, primarily functions to connect users to the internet securely. It does this by creating an encrypted tunnel between a user's device and a VPN server, which ensures that the data transmitted is protected from potential eavesdroppers. This is particularly important when using public Wi-Fi networks, where security risks are heightened. The encrypted connection helps to safeguard sensitive information, such as passwords and personal data, from cyber threats.

While VPNs can provide some level of content filtering and may allow users to bypass geographical restrictions by masking their IP addresses, their core purpose is to enhance security and privacy during internet access. By securing the connection, a VPN effectively protects users' online activities from being monitored, contributing significantly to user confidentiality in the digital space. This security aspect is why describing the VPN's function as a means to connect users to the internet securely is the most accurate choice.
