July 31st, 2017 – Middelharnis, The Netherlands  OPNsense is the fastest growing open source firewall and security platform released under an Open Source Initiative approved license.

The project combines the best of open source and proprietary firewalls. It offers a rich feature set, the benefits of open and verifiable sources and can be downloaded for free.

Deciso is proud to announce the immediate availability of version 17.7 named “Free Fox”. 

With a strong focus on security this major release introduces an innovative exploit mitigation technique called SafeStack. This innovation was made possible by the strong cooperation with the HardenedBSD project and introduces application hardening that protects programs against attacks based on stack buffer overflows.

Since the previous major release, the plugin infrastructure has grown significantly with the introduction of several – community supported – plugins such as a reliable, high performance TCP/HTTP load balancer, Quagga with broad routing protocol support and Let’s Encrypt for free and automated certificates.

The community has – yet again – shown a significant increase, further aiding to our goal of becoming the most widely used open source security platform available.

Users will notice the streamlining of various parts of the system and the significant GUI performance speedup for installation with a large number of interfaces.

For developers, the RESTful API and the pluggable infrastructure has been further improved and extended.

OPNsense® 17.7 is the first open source firewall to feature SafeStack at its core and the only actively developed security platform offered under a 2-clause BSD license. The team believes that open source allows for sharing of ideas and helps to creating better products.

“The ‘Free Fox‘, represents our focus, determination and commitment to an exceptionally featured, open and freely available security platform” – says Jos Schellevis, Deciso’s CTO.- “We are immensely proud to offer outstanding security for free. Special thanks go out to our active community members and partners who help to shape the future of our project.”

Deciso is the company that founded the OPNsense project and offers turnkey solutions as well as commercial support and services.
