VPN stands for “Virtual Private Network” and refers to a self-contained virtual network established via a physical network connection but is logically separate. In concrete terms, VPN means that you hide your IP and your real-time encrypted data via a protected tunnel and access your company or home network via another network (e.g. public Internet in a hotel or café).
If you set up a VPN connection in Windows 10, you must first distinguish between the Windows 10VPN and a third-party VPN. You can set up a VPN in Windows 10 using a known network and use your company or home network as a VPN without being on-site. In this case, the IP address of your VPN network will be visible. A third-party VPN, on the other hand, is used to secure an anonymous connection that encrypts your data, makes you invisible to attackers, obfuscates the IP, and bypasses geolocation blocking. VPN services are usually external providers like NordVPN, CyberGhost, TunnelBear or ExpressVPN.
