A VPN, or Virtual Private Network, is best described as a secure connection over a public network. This technology creates a private and encrypted tunnel through which data can travel over the internet or another public network. It protects users’ privacy by disguising their IP addresses and encrypting data, making it difficult for outsiders to intercept or access sensitive information.

The primary purpose of a VPN is to ensure that the data sent and received is secure from eavesdroppers and other cyber threats. As a result, it’s commonly used for secure communication, especially in remote work scenarios where employees connect to the company’s network from various public locations.

While there are devices and methods that can optimize network speed or solutions for data storage, those do not capture the essence of what a VPN does. Its primary function revolves around creating secure connections rather than optimizing performance or acting as a storage solution.
