Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Relativity
- Quote-only and expensive, typically billed on data volume, so costs escalate with matter size
- Complex enough that certified specialists are a job title, which is a real staffing cost
- Considerable overkill for small matters, where lighter self-service tools are far cheaper
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
