Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Namespace

  • Developer plan is pay-as-you-go only; minimum usage unclear
  • Team plan $100/mo is competitive but usage limits may be tight
  • Devbox pricing separate at $0.004/minute could add up quickly
  • Enterprise plan requires custom sales conversation

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
