This article explains how to recognize when a SIEM is out of control—frequent outages, incomplete investigations, undocumented data sources and overreliance on analysts—and recommends steps to regain control: gather stakeholder feedback, prioritize quick wins, tune high-volume low-value alerts, standardize logging and detection methodology (e.g., MITRE ATT&CK), decouple incident response from specific tools, and consider vendor, consultant, co-managed SIEM, or MDR support as needed.
