TL;DR: High log volume and alert noise are driving escalating SIEM costs, and applying asset criticality plus threat context at ingestion and alerting time can suppress low-value signals while elevating activity tied to real adversary behaviour, according to Anomali’s whitepaper. That shifts detection quality from volume management to context-aware triage.
Editorial analysis by NHI Mgmt Group, based on content published by Anomali: “Log Source Analytics and False-Positive Suppression with Anomali”.
Key questions
Q: How should security teams reduce SIEM noise without losing important alerts?
A: Focus on context, not volume.
Q: Why does asset criticality improve log analytics?
A: Asset criticality gives detections a business lens.
Q: What are the signs that SIEM suppression is going too far?
A: The warning sign is lower alert volume but weaker visibility into privileged activity, sensitive assets, or suspicious identity behaviour.
Practitioner guidance
- Implement ingestion-time enrichment Attach asset criticality, threat intelligence, and identity context before alerts are emitted so the pipeline can discard low-value events earlier.
- Score alerts by business impact Prioritise events touching crown-jewel systems, privileged identities, and critical services ahead of routine administrative activity.
- Tune suppression rules against adversary behaviour Preserve detections that match known threat patterns and remove repetitive alerts that do not change response decisions.
Bottom line: High log volume becomes a governance problem when SIEM platforms cannot distinguish routine telemetry from activity that affects critical assets.

Threat-informed log analytics is really a prioritisation problem, not a volume problem. The article shows that SIEM pain is often caused by treating all telemetry as operationally equal. Once asset criticality and threat context are available at ingestion time, the control question shifts from "how much can we collect?" to "what deserves analyst attention now?" Practitioners should design for decision quality, not log accumulation.
A question worth separating out:
Q: Should teams prioritise log volume reduction or detection relevance first?
A: Detection relevance should come first. Lowering volume without a context model only creates a quieter queue, while contextual prioritisation changes which events are surfaced and why, which is what improves analyst focus and operational outcomes.
