TL;DR: Telemetry pipelines are increasingly being asked to normalise, enrich, and route data before it reaches SIEM, because distributed systems, schema drift, and rising ingestion costs have made downstream-only observability too slow and too expensive, according to DataBahn. The governance shift is upstream: context now determines both security value and storage cost, so observability architecture becomes a data integrity and decision-making problem, not a dashboard problem.
Editorial analysis by NHI Mgmt Group, based on content published by DataBahn: “The Modern Observability Challenge for Enterprises”.
Key questions
Q: Where does pre-SIEM enrichment fail in practice?
A: It fails when teams treat enrichment as a post-ingestion convenience instead of a routing control.
Q: Why does enrichment timing change SIEM cost and detection quality?
A: Because the same context that improves triage also determines whether an event deserves expensive retention.
Q: What are the signs that an observability pipeline is failing in practice?
A: Common warning signs include duplicated data, missing data, runaway storage costs, and hard-to-debug routing logic across multiple agents.
Practitioner guidance
- Define enrichment points before SIEM ingestion Map where asset ownership, identity context, threat intelligence, and geolocation are added so routing decisions happen before ingestion costs are locked in.
- Classify telemetry by retention value Create clear rules for which enriched events merit full-fidelity SIEM retention and which can move to lower-cost storage without losing investigative usefulness.
- Preserve identity metadata in the pipeline Carry workload identity, asset provenance, and environment labels through collection and enrichment stages so analysts do not have to rebuild context later.
Bottom line: Raw telemetry that reaches SIEM without context forces security teams to pay for storage before they know whether the event is worth retaining.

Pre-SIEM enrichment is a governance control, not just a performance optimisation. Once telemetry volume, schema drift, and ingestion pricing are coupled, the question is no longer whether teams can see enough data. The question is whether they can decide fast enough which data deserves SIEM-tier treatment. For IAM and NHI programmes, that means identity context must be preserved upstream, not reconstructed later. Practitioners should treat enrichment timing as part of control design.
A few things that frame the scale:
- Kubernetes production adoption has surged from 66% in CNCF's 2023 survey to 82% in 2025.
A question worth separating out:
Q: Should teams centralise enrichment or keep it close to the source?
A: They should keep it as close to the source as throughput and governance allow. Centralising everything in the SIEM increases cost and delays context, while source-adjacent enrichment gives the pipeline enough information to route, tier, and retain data intelligently.
