What is a VPN?

VPN is the abbreviation for Virtual Private Network.

VPN: Virtual Private Network

VPN is the abbreviation for virtual private network. While a classic private network works via electrically isolated lines in routers and switches, a VPN is a virtualization of this private network.

Devices within a VPN are "among themselves" and cannot be reached from an external network. This provides a secure environment, particularly for critical infrastructure such as security technology.

VPNs can also be used to secure data connections over the internet. Data packets are encrypted when sent, transmitted encrypted over the Internet and decrypted again on the receiving end. With wherever SIM , various VPN services are available to you on the platform side.

OpenVPN: Open Source for setting up the virtual network

OpenVPN was first released in 2001 under the open source license. In simple terms, OpenVPN consists of two components: The VPN security protocol and a standalone software. Thanks to the open source concept, this is free of charge for anyone who wants to use it.

With this free OpenVPN software, you set up your virtual and encrypted network to a VPN server and establish a secure connection to the Internet via it. This connection is also known as a "tunnel". Your own computer or the network-compatible device that supports OpenVPN can then be reached under the IP address of the server.
