Cribl vs Splunk Data Stream Processor -- Security Data Pipeline Compared

Cribl vs Splunk Data Stream Processor

Splunk DSP is a natural choice for existing Splunk customers who want to optimize data before ingest, leveraging familiar SPL syntax and tight platform integration. Cribl is the better choice for organizations wanting a vendor-agnostic pipeline that routes data to any destination, not just Splunk, with more powerful transformation and reduction capabilities.

The Verdict

Choose Splunk DSP if you are committed to the Splunk ecosystem and want to optimize data ingest with familiar SPL tooling. Choose Cribl if you need a vendor-agnostic pipeline that supports any destination and offers more powerful data transformation and reduction capabilities.
