TL;DR: Legacy SIEM models are breaking under alert overload, with 88% of security teams struggling with rising volumes and 76% reporting alert fatigue, according to Gurucul. The real issue is not just noise but the visibility trade-off created by rigid ingestion economics and static detection design.
Editorial analysis by NHI Mgmt Group, based on content published by Gurucul: “Why Your SOC Team is Flying Blind and 3 Ways to Fix It”.
By the numbers:
- 88% of security teams struggle with increasing alert volumes.
- 76% report suffering from alert fatigue.
Key questions
Q: What breaks when SIEM telemetry is incomplete?
A: Detection rules break first, then trust in the SIEM follows.
Q: Why do static SIEM rules fail against modern threats?
A: Static SIEM rules fail because they assume threats will repeat known patterns in predictable ways.
Q: What are the signs that a SOC is drowning in alert fatigue?
A: The clearest signs are rising alert counts, long triage queues, repeated false positives, and analysts who start discounting alerts before they investigate them.
Practitioner guidance
- Define mandatory telemetry tiers Classify identity, cloud, endpoint, and authentication logs into must-ingest, enrich-before-ingest, and optional tiers so cost decisions are explicit.
- Measure alert fatigue as a control failure Track alert volume, false-positive rate, and analyst dwell time together so you can see when the SOC is spending effort on low-value noise.
- Introduce behaviour-based detections for identity activity Prioritise detections that compare current activity to established baselines for users, service accounts, and workloads instead of relying only on static rules.
Bottom line: Legacy SIEM models are failing because cost pressure and alert overload are driving organizations to accept incomplete visibility.

Alert fatigue is now a detection-governance problem, not just an operations problem. When 76% of teams report alert fatigue and 88% struggle with alert growth, the failure is no longer simply volume. It is the inability of SOC governance to preserve analyst attention for the events that matter most. The practical consequence is that detection quality becomes a lifecycle issue for the SOC itself, not a tuning exercise.
A question worth separating out:
Q: How should security teams reduce SIEM costs without creating blind spots?
A: Security teams should move from ingest-everything thinking to governed data routing. Preserve full-fidelity logs for identity, access, and high-risk events, enrich and normalize data before it reaches the SIEM, and keep raw evidence in cheaper storage for audit and replay. The goal is to reduce noise and cost without losing investigative depth.
