. The Command Line Tool, which is the cli interface for involving with the solution
. This command uses basic metrics regarding parsers, quantity of logs refined, selection of threats located and also obstructed for each and every collection (see over for a listing of collections).
2 deals will certainly be readily available: Premium as well as Enterprise with support solutions, unique solution devices (such as releasing the system to a variety of areas from one major location), use of information mining as well as manufacturer training (finding patterns in globally information), advanced cool log evaluation (forensics, examinations).
