What is the purpose of a VPN?

A Virtual Private Network (VPN) primarily serves the purpose of creating a secure point-to-point tunnel between two or more networked devices. This tunnel encrypts the data transmitted over the internet, ensuring that it is shielded from eavesdropping, interception, and other malicious activities. By establishing this secure connection, a VPN allows users to send and receive data as if their devices were directly connected to a private network, enhancing privacy and security even when using public networks.

While other choices touch on aspects of online security or performance, they do not encapsulate the primary functionality of a VPN as accurately as the creation of a secure tunnel. Enhancing bandwidth, securing transactions, or managing user sessions are important elements in different contexts but are not the core function of a VPN. The main objective remains the establishment of a secure communication pathway, which is fundamental for protecting sensitive data transferred over potentially risky environments such as the internet.
