Splunk Enterprise Security
- Owner

- Pricing model
- Ingest-based (per GB/day) plus Workload Pricing alternative. ES is an add-on layered on Splunk Cloud or Enterprise. Multi-year discounts of 20-30% are routine.
- Cheapest rate
- Quote-only. Channel reports list $2,000-3,500/GB/year on base platform; ES add-on $20-40/GB/day on top.[1]

Decision rule
Securonix per-identity pricing decouples cost from ingest volume. For a 1,500-employee shop at 400 GB/day with identity-led use cases Securonix usually wins on TCO; for ingest-heavy diverse workloads Splunk's per-GB still rules the spreadsheet.
Snowflake-backed retention
Securonix's Snowflake-native architecture keeps the data lake outside the SIEM vendor. For long-retention compliance workloads the per-TB-month cost beats Splunk hot-warm-cold tiering at most volumes.
