Welcome to the BSD Perimeter website. We are the leading provider of custom FreeBSD-based network security appliance solutions, as well as the official commercial support provider of the open source firewall pfSense, providing support, consulting and development services to a worldwide customer base. 

 

A barrier to choosing and implementing open source software is the availability of prompt, professional support from knowledgable individuals. We eliminate that barrier for pfSense users.

 

We offer support contracts, as well as related consulting and custom development services.

 

We also have created and maintain dozens of custom branded network security appliances for OEMs in hospitality, networking, security, industrial control systems, and other industries.
