TL;DR: Legacy SIEMs and monolithic SOC platforms struggle when organizations ingest terabytes of telemetry and still leave roughly two-thirds of alerts uninvestigated, according to DataBahn. The shift to security data fabrics changes the control problem from raw volume to governed routing, where context, filtering, and enrichment determine what reaches expensive detection tiers.
Editorial analysis by NHI Mgmt Group, based on content published by DataBahn: “Composable Security Platforms: Integrating Security Data Fabrics into the SOC Stack”.
Key questions
Q: How should SOC teams handle SIEM ingestion when telemetry volume keeps growing?
A: SOC teams should stop treating ingestion as a storage problem and manage it as a routing problem.
Q: Why do monolithic SIEM architectures become harder to sustain as telemetry sources grow?
A: They break down because more applications, hosts, and cloud services produce too much data for a single pane of glass to remain useful.
Q: What are the signs that SIEM ingestion is creating operational blind spots?
A: Common signs include delayed onboarding of new sources, escalating licence costs, growing false-positive backlogs, and repeated complaints that analysts are buried in noise.
Practitioner guidance
- Define routing policy before tooling sprawl expands Map which telemetry must reach SIEM, which can go to cheaper storage, and which should be suppressed at collection time.
- Push enrichment to the edge Attach asset, identity, and threat context as close to collection as possible so retention and forwarding decisions happen before premium ingestion costs are incurred.
- Separate detection from delivery Keep routing and enrichment logic independent from SIEM and XDR content rules so tools can be swapped or scaled without redesigning the data plane.
Bottom line: Legacy SIEM architecture struggles when security teams equate volume with visibility and pay to ingest data that never becomes useful signal.

Security data fabrics are a governance layer, not just an integration pattern. The article shows that routing, enrichment, and filtering now decide whether telemetry becomes actionable intelligence or expensive noise. That makes data movement itself a security control surface, especially when SOCs rely on multiple tools that each expect different context. Practitioners should evaluate fabric policy with the same discipline they apply to access policy.
A question worth separating out:
Q: How do security data fabrics change the way SOC tools should be organised?
A: They decouple collection from analytics so routing, enrichment, storage, and detection can evolve independently. That means teams can feed SIEM, XDR, SOAR, and data lakes from the same governed pipeline instead of hardwiring every source into one monolithic platform.
