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.
A virtual private network (VPN) is a mechanism for creating a secure connection between a computing device and a computer network, or between two networks, using an insecure communication medium such as the public Internet.A VPN can extend access to a private network (one that disallows or restricts public access) to users who do not have direct access to it, such as an office network allowing secure access from off-site over the Internet. The benefits of a VPN include security, reduced costs for dedicated communication lines, and greater flexibility for remote workers.A VPN is created by establishing a virtual point-to-point connection through the use of tunneling protocols over existing networks. A VPN available from the public Internet can provide some of the benefits of a private wide area network (WAN).
