TL;DR: Pre-SIEM enrichment can cut SIEM-bound data volume by 50% to 70% and reduce licensing costs by more than half when context is attached before ingestion, according to DataBahn’s analysis of modern SOC pipelines. The real shift is governance as much as economics: enrichment must become a pipeline control, not a post-processing step.
NHIMG editorial — based on content published by DataBahn: Why are Legacy SIEMs a problem?
By the numbers:
- Organizations applying pre-SIEM filtering and enrichment have reduced SIEM-bound data volume by 50 to 70 percent, cutting licensing costs by more than half.
- One medical device manufacturer running OT-heavy manufacturing sites cut Splunk costs by over 50 percent within seven days of deploying edge-level filtering and enrichment.
- The survey reported that 96% of global organizations have deployed AI models.
Questions worth separating out
Q: How should security teams decide which telemetry belongs in the SIEM?
A: Start with investigative value, not source count.
Q: Why do legacy dashboards fall short for modern SOC operations?
A: Because they describe what already happened rather than supporting decisions in motion.
Q: What breaks when enrichment happens after ingestion instead of before it?
A: The SIEM has already charged you for the event before context can influence the decision.
Practitioner guidance
- Implement pre-ingestion routing for high-volume telemetry Classify events before they reach the SIEM so known-low-value logs can move to cheaper storage while high-value security events retain full fidelity.
- Attach identity context in flight Resolve users, service accounts, workloads, and asset ownership while data is moving through the pipeline.
- Replace synchronous enrichment calls with cached lookups Use pre-indexed threat feeds, cached high-frequency values, and asynchronous external queries so enrichment does not block throughput.

Pre-SIEM enrichment is a governance control, not just a cost tactic. The article correctly frames the economic pain, but the deeper issue is that post-ingestion enrichment forces teams to govern after they have already paid for the data. That is a weak control model in environments where telemetry is continuous and context-sensitive. The right lesson for practitioners is that routing, enrichment, and retention need to be decided before ingestion, not after.
A question worth separating out:
Q: How do teams measure whether enrichment is actually working?
A: Measure whether enrichment changes analyst behaviour and response speed, not just whether more feeds are connected. Good enrichment reduces manual pivots, improves alert quality, and helps analysts close cases with higher confidence. If the team still exports data to other tools for basic validation, the enrichment layer is not doing enough.
