I like how easy it is for us as users (and also admin) of this system, because everything can be done through one interface which really saves time when doing tasks in our business daily life - monitoring security incidents from different sources/devices etc.,etc..
nothing at all so far! The only thing that we sometimes miss are some more options about what data you want to show or filter out e.g. search option would help alot with finding specific information if needed quickly!! That's why i rate their product 9-10 :).
