“What’s the benefit is of adding Qradar’s QFlow Collector when I already have the event data being collected with Qradar's SIEM?” Being able to collect Flow and Event data (Siem and QFlow conmbined) not only gives you a better view as to what is happening on your network it also allows you to the view flow of events that are coming in. This greater visibility will allow you to better detect threats, meet policy and regulatory compliance requirements and minimize risks to mission critical data, services and assets.
