When is a VPN commonly used?

A Virtual Private Network (VPN) is primarily used to create a secure and private connection over a public network, such as the Internet. This technology employs encryption and tunneling protocols to protect the data transmitted between the user’s device and the server. By establishing this secure connection, users can safeguard their sensitive information from potential eavesdropping or interception by unauthorized parties.

Using a VPN is particularly beneficial when accessing public Wi-Fi networks, where security vulnerabilities are prevalent. It allows users to browse the internet, access corporate networks, or connect to private resources from any location while maintaining confidentiality and integrity of the data being transmitted.

This capability is essential for remote workers, travelers, or anyone needing to access restricted content or internal company systems securely from outside the office environment. Thus, the primary purpose of a VPN aligns with the need to securely connect to a network, making this option the most applicable choice.
