A virtual private network (VPN) is a type of network technology that enables users to create a secure and encrypted connection over a public network, such as the internet. The primary purpose of a VPN is to provide a secure and private connection to a remote network or server.

When you connect to a VPN, your device creates a secure tunnel to the VPN server, which then encrypts all data that passes through it. This encrypted data is then sent over the public network, such as the internet, and can be decrypted only by the VPN server. This ensures that your data is protected from hackers and other unauthorized access, even when you’re using an unsecured public Wi-Fi network.

VPNs are often used by businesses to allow remote employees to securely access company resources, but they’re also used by individuals who want to protect their online privacy, bypass censorship or geo-restrictions, or access region-restricted content.
