The biggest issue that I see companies run into is that they immediately think that, "Oh, this solution will be right, simply due to the name." But that's the same issue Splunk runs into. People will immediately jump to Splunk being the best SIEM tool, just because they're the largest. When in reality, QRadar, LogRhythm, and all these other ones are performing similar functions and would actually fit better in some people's environments. Therefore, it's important a company does its homework and does not assume one size fits all.
