What is the purpose of a Virtual Private Network (VPN)?

A Virtual Private Network (VPN) is designed primarily to allow users to connect to a private network securely over a public network, such as the internet. This capability is crucial for maintaining the confidentiality and integrity of data as it travels from one location to another. By establishing a secure, encrypted connection over less secure networks, VPNs protect sensitive information from potential eavesdropping or interception by unauthorized parties.

The secure connection created by a VPN not only facilitates access to private resources as if the user were directly connected to the private network, but it also ensures that any data transmitted is encrypted, thereby enhancing security. This is particularly valuable for remote work scenarios or when accessing sensitive company resources from public locations.
