The primary purpose of a Virtual Private Network (VPN) is to create a secure tunnel that allows for the transmission of sensitive data over an insecure network. This secure tunnel encrypts the data being transferred, protecting it from interception and eavesdropping by unauthorized individuals, particularly in public or unsecured networks such as Wi-Fi in cafes or airports. By using a VPN, users can maintain their privacy and secure their communications against potential security threats.

Although some may mistakenly believe that a VPN can enhance internet browsing speed or facilitate online gaming, those are not its main functions. A VPN may occasionally improve speed due to reduced throttling by an Internet Service Provider, but its fundamental design is primarily focused on privacy and security rather than performance. Similarly, while some gaming platforms can use VPN technology, that is not the purpose of a VPN. Lastly, monitoring user activities isn’t the function of a VPN; instead, it aims to protect users' data and maintain confidentiality. Thus, the essence of a VPN firmly lies in its capacity to ensure secure data transmission.
