Splunk Customer Satisfaction Rating
An Engineer at a small business financial services company would be very likely to recommend Splunk for this reason:
I have used four different SIEM products at this point, and none are as good as Splunk. The sheer customizability is what gives it a 10-out-of-10 score. Even though the customization adds a certain level of challenge/difficulty, as long as one is up to the task, Splunk is the way to go.
