What is a key feature of VPN technology?

A key feature of VPN technology is that it creates a secure tunnel over public networks to protect data transmission. This aspect is crucial because it ensures that information sent between the user's device and the VPN server is encrypted, shielding it from potential eavesdroppers. By establishing this secure tunnel, VPNs provide confidentiality and integrity for the data being transmitted, which is especially important when using public Wi-Fi networks or any untrusted internet connection.

Establishing a secure connection also helps to maintain privacy by masking the user's IP address and allowing access to resources that may be geographically restricted. This feature highlights the primary purpose of a VPN: to safeguard data and enhance security while using the internet, making it an essential tool for individuals and organizations seeking to protect sensitive information.
