The challenge
Stop paying SIEM prices for low-value telemetry
SIEM pricing makes raw telemetry expensive at scale. High-volume sources overload analytics platforms with repetitive, low-value logs, increasing ingestion costs and analyst noise. Limited control over data volume and quality before ingestion forces teams to balance cost pressure with visibility.
The Solution
DataStream – a cost-control layer for SIEM ingestion
Cut volume without losing security context
DataStream reduces data at the field level, removing redundant and low-value content while preserving detection-relevant context. This avoids the common failure mode of dropping entire events or columns and hoping nothing breaks.
Apply the right data tier for each use case
Send high-value detections to the SIEM, route bulk telemetry to a data lake, and keep long-term retention in low-cost storage while remaining investigation-ready.
Measure savings at every step
Before deployment, you can run a sample of your own logs through the pipeline and see the expected reduction. After deployment, DataStream tracks volume and cost for each destination. You report savings from measured data.
Use risk-free reduction
DataStream applies deterministic reduction rules built from real detection content. Outcomes are predictable and fully auditable, and security-relevant data is protected from silent loss.
Key benefits
Why this approach works
Impact
Immediate, measurable impact on your SIEM budget
- 50–90% less ingestion volume
- 25–75% less manual work for parsing, scripting, and pipeline maintenance
- Lower indexing and query costs across analytics workloads
Frequently asked questions
Can you reduce SIEM ingest without breaking detections?
Yes. DataStream is designed to reduce ingestion volume while preserving the security context required for detection and investigation. We achieve this by removing irrelevant fields from the logs, based on Microsoft’s ASIM Schema.
Do you drop events by default?
No. Event-level filtering is optional and disabled by default. Conservative deployments start with field-level optimization first.
Can we keep full logs for forensics and retention?
Yes. DataStream supports tiered storage patterns where optimized data goes to the SIEM and full-fidelity logs can be retained in low-cost storage with correlation mechanisms.
Does this help beyond cost reduction?
Yes. Reduced noise, normalized telemetry, and better routing improve analyst experience and detection operations alongside the budget impact. By freeing up SIEM budget you can also add additional data sources to close visibility gaps and improve detections and cyber resilience.
How can I see the actual ingest reduction?
The Stats page shows data volume and ingest reduction for each destination. Before you deploy a change, you can see its expected effect on a sample of your own logs.
