What is the difference between Splunk Enterprise 6.3 and SAP Enterprise Threat Detection

Hi , I was wondering if someone can help with what the difference between SAP Enterprise Threat Detection and also Splunk 6.3 for SAP. my understanding is that Splunk can be used to gather and analyse any logs event on SAP in order to detect anomalies in realtime using SAPNinja build (or please correct me). If SAP ETD also does a correlation of all logs on SAP applications using the SAP /syabse events stream processor, does this mean they are both competing solutions or can they complement each other ? is there anyone who can give some clarification here ? thanks Tunde Ogunkoya
