What is an OpenVPN?
OpenVPN is a VPN tunnel protocol, it creates a secure and encrypted internet connection between several devices communicating online. There are other popular tunnel protocols like PPTP, L2TP/IPSec, SSTP and others, these work a little differently when establishing the secure VPN network.
OpenVPN is one of the most well known and popular of all tunnel protocols used by VPN software solutions. It offers many great features, it’s easy to use and offers extensive support. Open VPN is an Open Source software that can be used by anyone and modified when needed. The best use of OpenVPN is for anonymous and private internet access, however it can be used also for other various connection needs.
As OpenVPN works in client server mode, then this means that connection to the internet goes through OpenVPN server. Once a client connects to the server, it uses the server to encrypt all of its internet traffic and data, which allows client to appear as the server and it assumes that the user’s physical location and administrative contacts are the same as the server’s location. Because of this process the privacy of the OpenVPN user is fully protected and secure.
If you wish to start using OpenVPN you have to secure access to the OpenVPN server to connect to. It’s possible to install your own OpenVPN server, however it isn’t that easy and requires more technical knowledge, also it can lack main privacy features that you require from OpenVPN, therefore the best is to use of of the best VPN providers, like ExpressVPN, VyprVPN, StrongVPN, SaferVPN or HideMyAss that already support OpenVPN protocol and offer many other advantages.
