What is OpenVPN?
OpenVPN is an open source solution that makes it possible to safely connect different devices. OpenVPN is often recommended because the security is quite good. The code is public, so vulnerabilities can be found and solved really fast. OpenVPN also uses OpenSSL, which secures connections with a strong encryption. OpenVPN can be set up in a way that makes it impossible to distinguish internet traffic through this software from normal internet traffic. It is therefore extremely difficult to block.
