[http:/ /www. halon. se Halon Security] is primarily the developer of a hosting- grade, scriptable [ http:// wiki. halon. se/Overview email platform] , but also offers the '' security router'' (SR). It' s a network operating system and software distribution based on OpenBSD[http:// en. wikipedia. org/ wiki/ OpenBSD] , with the main differentiator being the single, revision-managed, clear-text [[configuration file]] with [[backend|soft re-configuration]] (atomic commits) editable from [[configure|CLI]] and web interfaces ([http:// sr.demo. halon. se live demo] ), and documented security [[ architecture]] .
In general, it' s a routing platform with security and VPN features. It aims to be a replacement for proprietary solutions like Cisco IOS[http://en.wikipedia.org/wiki/ Cisco_IOS] and Juniper Junos[ http://en.wikipedia.org/wiki/Junos] . You can download it for free from http://dl2.halon.se/vsr/ and run it from ( for example) a USB stick in a x86 computer (anything from the affordable ALIX[http:// www. pcengines. ch/alix.htm] to high end systems with 10GE cards), or as a virtual machine. New user are encouraged to read the [[ getting started]] page.
came to life because we wanted a router/ firewall with Unix [[root access] ], strict security [ [architecture] ], [ [SOAP|API] ]s and a beautiful [[configuration file]] that applied atomically ( enabling for example rollbacks without rebooting). The file system is read-only, enabling it to be run from USB thumb drivers or CompactFlash cards. It doesn't need to be "installed", the software can be [[Writing system images|written directly onto]] for example a USB stick. The system is a mix of open (web interface, system scripts, LCD interfaces, patches, OpenBSD) and closed ([[ backend]] ) source.
