What is the main function of a VPN?

The main function of a VPN (Virtual Private Network) is to create a secure and encrypted connection over a less secure network, such as the internet. This enables users to send and receive data as if their devices were directly connected to a private network, enhancing the protection of sensitive information from potential eavesdroppers or cyber threats. By encrypting the data transmitted, a VPN helps maintain privacy, security, and data integrity, especially when accessing public Wi-Fi networks.

While enhancing speed for internet connections, limiting access to certain websites, and backing up data remotely are important functions in various contexts, they do not represent the primary purpose of a VPN. The core objective remains focused on establishing a secure communication channel, which is critical for protecting data in transit.
