The huge library especially the open source link, makes it the main engine for Corelight with some enhancements in the commercial version. It has a very powerful level, such as signature-based attacks or behavioral attacks, with enhancements in the design. It is very flexible for intelligent implementations like IPs, especially between big companies and banks. Corelight is easy to understand and monitor what is going on behind the team. The solution is already integrated with other systems like Suricata, Elastic, and Microsoft tools. It's very easy to integrate signature-based or behavior-based engines. You can use Elastic for the dashboards to get it from Corelight, along with all the benefits and expandability.
