About this tool
Security Alert Threshold Calculator
The Security Alert Threshold Calculator computes per-analyst alert load, false positive impact, and alert quality score with fatigue threshold comparison.
• Assess whether current alert volume creates analyst fatigue
• Calculate per-analyst daily alert load before hiring or tuning decisions
• Identify whether false positive rate is above the trust-erosion threshold
• Model alert load reduction from SIEM tuning to reduce false positive rate

FAQ
What does this tool tell you?
The Security Alert Threshold Calculator computes per-analyst alert load, false positive impact, and alert quality score with fatigue threshold comparison.
What affects the result most?
Alert fatigue: >20 actionable alerts/day per analyst is burnout threshold — quality over quantity. False positive rate: >10% false positive rate erodes analyst trust — ignored alerts are invisible alerts. True positive rate: for high-fidelity rules aim >70% true positive — tune before deploying broadly.
How should I use the result?
The calculation is deterministic — the same inputs always produce the same output — so the most useful workflow is to vary one input at a time and see which factor moves the result most. That tells you where to focus your attention before committing to a decision.
