OpenAanval was originally a very simple web front-end to monitor and browse Snort event data.
OpenAanval was the stand alone free limited version of the commercial Aanval console before it was finally integrated in 2005.
Aanval continues to support the snort community, by providing users with a free limited version of Aanval that allows full functionality of a single snort and syslog sensor.
Aanval operates in this free limited mode when no licenses are available or can be detected.
Aanval was also known as ComAanval for a short period of time, before all code was centralized and provided as a single package.
