TNSR Software


pfSense Software


The Netgate pfSense® software user base includes every industry vertical, businesses from small to enterprise, local, state and federal government agencies, educational institutions and consumers.

Not surprisingly, It is often asked how pfSense software and TNSR® software differ.

Simply stated, the pfSense project is an open-source firewall software distribution, and TNSR is a high-performance software router.

pfSense software has been in use since 2006, and covers a wide variety of secure networking solution needs. TNSR software is much newer, and to date has been more targeted in its secure networking solution coverage.

While it is entirely possible and plausible that some secure networking use cases can be addressed by either product (albeit with dramatically different performance), TNSR software is not positioned as a “pfSense software replacement”.
