Enterprise observability and SIEM — powerful, staggeringly expensive, and now Cisco's
What Splunk costs, how it compares to similar DevOps, Monitoring & Observability tools on price positioning, and every documented billing complaint that's shaped its reputation.
Splunk is an enterprise platform for log management, security information and event management (SIEM), and observability. Acquired by Cisco in March 2024 for $28 billion. Pricing is based on daily data ingest volume — typically $150–200/GB/day — making it one of the most expensive observability platforms. Used primarily by large enterprises and government organizations.
The cost is the defining complaint. At $150–200/GB/day, an enterprise ingesting 100 GB/day pays $5.5–7.3M annually for Splunk licensing — a price that has driven an entire industry of alternatives (Elastic, Sumo Logic, Cribl) and a significant portion of the SRE community dedicating conference talks to reducing Splunk spend.
The Cisco acquisition in 2024 introduces uncertainty about product direction and pricing — the kind of acquisition that historically drives customers to evaluate alternatives.
