pfSense Firewall
Open Source solution for infrastructure security

FreeBSD based software adapted to take on the role of a firewall and/or network router. It has features that often only be found in expensive commercial firewalls, since we can perform with pfSense the vast majority of the activities we expect from systems with this title.

The pfSense project was conceived in mid-september 2004 by Chris Buechler and Scott Ullrich. Chris was a long time contributor to the m0n0wall project. It has improvements over the m0n0wall project in the configuration web interface and an approximation with lastest versions of FreeBSD (base system). The system has won users by being extremely organized and adding a series of features with easy access, allowing a layman who has basic knowledge of network, install and manage a pfSense system.

OpenVPN
Open Source VPN Solution

It's 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 translators (NATs) and firewalls. It was written by James Yonan and is published under the GNU General Public License (GPL).

Allows peers to authenticate each other using a pre-shared secret key, certificates or username/password. When used in a multiclient-server configuration, it allows the server to release an authentication certificate for every client, using signature and certificate authority. It uses the OpenSSL encryption library extensively, as well as the SSLv3/TLSv1 protocol, and contains many security and control features.
