Virtual Private Network (VPN) is a tool that provides an encrypted secure tunnel between two networks or between a client device and a network. Enterprises use VPNs to allow secure connection of mobile devices like laptops and smart devices to the internal company network. Typically when you are in a company office a VPN will not be needed, but when you are working from a coffee shop or from home then a VPN can give you secure access to company servers and systems.
