A virtual private network (VPN) is a secure connection between two or more devices that uses a public network, such as the Internet, to exchange data. It creates a secure, encrypted tunnel through which data is sent. This makes it difficult for attackers to intercept the data and prevents your data from being accessed or monitored by anyone else on the network. VPNs are often used to give employees secure access to a company’s intranet or other internal resources from outside the office, or to securely connect two or more offices together. They can also be used for security when using public Wi-Fi hotspots.
