TL;DR: Detection programs are often measured by content volume, not operational health, leaving teams with rules that look covered but are silent, noisy, or decayed in production, according to AiStrike. The real problem is proving detections still work against live telemetry, and that is now a governance issue as much as an engineering one.
Editorial analysis by NHI Mgmt Group, based on content published by AiStrike: “AiStrike”.
Key questions
Q: Why do detection rules fail even when SOC coverage looks complete?
A: Coverage metrics only prove that a rule exists and is deployed.
Q: When should security teams prioritise fixing noisy detections over adding new ones?
A: When high-volume alerts are consuming analyst time without contributing to confirmed investigations.
Q: What are the signs that a detection estate is decaying?
A: Look for rules that once fired but no longer do, detections tied to retired data sources, and alerts that stopped after a schema or platform change.
Practitioner guidance
- Inventory detections by last successful fire Export the production rule set and sort it by last execution or last alert.
- Validate every silent rule against live data sources For each rule that has not fired, confirm the source is live, the schema still matches, and the fields still populate.
- Measure noise against confirmed incident value Take the highest-volume detections and compare alert volume with confirmed investigative value.
Bottom line: Detection programmes can look complete while still containing rules that are silent, noisy, or decayed in production.

Detection health is now an operational control, not a reporting metric: teams that only measure content volume confuse inventory with assurance. A SOC can publish strong coverage numbers and still miss attacks if live data quality, schema continuity, or environment changes break the rule path. Practitioners should treat detection validation as part of control ownership, not a periodic clean-up task.
A few things that frame the scale:
- 96% of security operations teams report critical blind spots, most commonly in cloud infrastructure (74%) and identity and access behaviour (67%).
A question worth separating out:
Q: How should SOC teams prove that detection content still works?
A: Replay recent telemetry, validate every data dependency, and simulate the behavior the rule is supposed to catch. If the rule does not match historical activity or current attack patterns, it should not be treated as a reliable control.
