What is a VPN and how does it enhance security?

A VPN, or Virtual Private Network, plays a crucial role in enhancing security by creating a secure, encrypted connection over less secure networks, such as the internet. This secure tunnel ensures that all data transmitted between the user's device and the VPN server is encrypted, which protects against eavesdropping and interception by malicious actors. When you use a VPN, your IP address is masked, making your online actions more difficult to trace, thereby contributing to privacy.

The encryption provided by a VPN protects sensitive information, such as passwords and personal data, as it travels across the internet. This is especially important when using public Wi-Fi networks, where the risk of data theft is significantly higher. The ability to connect securely to a remote network also allows users to access restricted or geo-blocked content safely and securely.

Other choices describe alternative concepts that do not accurately represent the function and benefits of a VPN. Vulnerability Protection Networks focus on identifying and responding to threats rather than creating secure connections. A Virtual Private Node does not exist in the context of VPNs and incorrectly implies control over user access without addressing encryption and secure connections. Lastly, a Value Protection Network inaccurately implies that a VPN is specifically aimed at securing financial data rather than providing overarching security for all types of information
