Product Overview

OpenVPN

Description: OpenVPN 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 uses a custom security protocol that utilizes SSL/TLS for key exchange. It is capable of traversing network address translation (NAT) and firewalls.

WireGuard

Description: WireGuard is an extremely simple yet fast and modern VPN that utilizes state-of-the-art cryptography. It aims to be faster, simpler, leaner, and more useful than IPsec. WireGuard is designed as a general purpose VPN for running on embedded interfaces and super computers alike.
