Splunk Enterprise Security
- Splunk Enterprise Security is licensed separately from the Splunk platform, so a SIEM deployment needs both
- Splunk publishes no rate for Enterprise Security and directs buyers to contact a pricing expert
- UEBA, SOAR and automated threat analysis require the Premier edition rather than Essentials
- The platform underneath can be billed by ingest volume, workload or activity, so the total cost depends on a pricing model chosen at contract time rather than a list price
