Most organizations send 40%+ of their ingest to SIEM systems that never trigger a detection. Cribl Stream sits between your sources and SIEM to reduce, deduplicate, and sample your way to dramatically lower costs while preserving detection coverage.
Noisy sources are eating your budget. Every GB costs the same whether it’s a critical alert or DNS noise. You’re drowning in routine logs that will never trigger a detection.
Your SIEM vendor charges per GB ingested. Data grow 20–30% annually while budget stays flat. Security teams want full-fidelity data, but your CFO is asking why you’re paying top dollar for logs that sit in cold storage.
The worst part? You can’t just shut it off. You need that data somewhere — in your lake, in your archive, for compliance. You just don’t need to send it all to your SIEM.
Cribl Stream sits between your sources and SIEM. Think of it as a smart filter that understands your ingest topology, your detections, and your cost model.
Remove unnecessary fields. Deduplicate redundant logs. Sample high-volume noise. Route full-fidelity data to your lake for deep investigation. Send only essential, high-signal events to SIEM.
The result: 40%+ ingest reduction to SIEM, full visibility elsewhere, and security coverage stays intact.
Ingest volume audit • Top log source identification • Cost-per-source analysis • Detection coverage mapping
Pipeline rules for trimming/dedup/sampling • Field reduction for low-value sources/empty fields • Lake routing for full-fidelity backup • Ingest guardrails
Ongoing volume monitoring • New source cost modeling • Quarterly optimization reviews • Budget forecasting
A major healthcare system used Cribl Stream to consolidate their SIEM environment and migrate to Microsoft Sentinel. The deployment reduced SIEM ingest by 40%, centralized 30,000+ endpoints under a single pipeline, and completed full cutover in two weeks — without losing detection coverage.
