VPN or Virtual Private Network is an encrypted path between a device and a network over the internet. VPNs ensure the security of transmitted data by providing encrypted channels for data flow. In this way, communication between the two entities involved remains secure. It also prevents intruders from intercepting the data traffic from one end to the other. VPN software is available for all operating systems. So you can easily install and use them.
To manage these VPNs, there is a special protocol called OpenVPN. It acts as an interface between the VPN server and the client. If this protocol is installed on your operating system, you can easily install any VPN software. This article will explain how you can check whether OpenVPN is installed on Ubuntu.
