We are dedicated to providing the world a strong, clusterable firewall for virtual environments. As is common with us, every opensource software we make stays opensource. We envision a bright future with VirtualPF.
Our mission is very simple: to deliver the best firewall product there is for virtual environments — Hyper-V, XenServer, VMware, Proxmox.
We do our very best to make the world of Internet a safer place for all. We fulfill this mission by improving the firewall over time with continuous and stable development.
All of us in the VirtualPF team love our jobs, and we are passionate about servers and networks as well as the technologies behind them.
This love is reflected in our absolute commitment to every task we perform. We are not out there merely for financial gain. We are there to find effective SOLUTIONS to your server and security related problems.
The pfSense project was started in September 2004 by Chris Buechler and Scott Ullrich.
Chris is a long time contributor to the m0n0wall project. m0n0wall is a great embedded firewall, but one of the great things about its design is also a limitation to expandability. m0n0wall runs entirely from RAM, the entire OS and all applications are loaded into RAM at boot time.
This is a great design for embedded systems, for performance and reliability reasons. However m0n0wall is not capable of being installed into a normal file system on a hard drive.
