What is the main function of a VPN?

The main function of a Virtual Private Network (VPN) is to provide an encrypted connection over the Internet. A VPN creates a secure tunnel between your device and the VPN server, encrypting the data that travels through it. This encryption protects sensitive information from being intercepted by hackers or other malicious entities while it travels across public networks. Additionally, a VPN helps users maintain their privacy by masking their IP addresses and making their online activities more anonymous.

While enhancing firewall capabilities, monitoring network traffic, and detecting intrusions are important aspects of overall network security, they do not capture the primary purpose of a VPN, which is fundamentally about securing and encrypting data during transmission across the Internet.
