==Summary==
==Summary==
<b>OpenVPN</b> is an open-source software application that implements virtual private network (VPN) techniques for creating secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities. It is often regarded as being the most universal VPN protocol because of its flexibility, support of SSL/TLS security, multiple encryption methods, many networking features and compatibility with most OS platforms.

==Stunnel==
Stunnel is an open-source a proxy service that adds TLS encryption to clients and servers already existing on a VPN network.
TLS encryption provided by Stunnel can be used as an additional layer of encryption for data sent by VPN.
This procedure increases the security of the established connection and provides higher chances of passing a Deep packet inspection (DPI) check.
