VPN

a VPN (Virtual Private Network) is a private network that runs on top of a larger network. Most often we use this term when we are talking about encrypted connections between two devices like routers, firewalls or remote users. Even something as simple as a VLAN could be considered a VPN, it’s “virtual” and you are the only one (private) that is using it. MPLS VPN is another good example, it offers a private “connection” for customers but there is no encryption involved. These lessons cover a variety of topics where VPNs are used.
