AI-Powered Alert Triage

Deploy intelligent alert classification systems that automatically categorize, prioritize, and route security alerts, dramatically reducing analyst workload and response times.

Automated Classification

ML models classify incoming alerts into actionable categories based on historical analyst decisions:

CategoryActionExample
True Positive - CriticalImmediate analyst attention + auto-containmentActive ransomware encryption detected
True Positive - HighPriority queue for next available analystCredential theft attempt from unknown IP
True Positive - MediumStandard investigation queueSuspicious PowerShell execution on workstation
Benign/FPAuto-close with documentationLegitimate admin tool triggering detection rule

Priority Scoring Model

  1. Alert Attributes

    Score based on detection rule confidence, attack technique severity, and historical true positive rate for this alert type.

  2. Asset Context

    Weight by target asset criticality, data sensitivity, and business impact. A hit on a domain controller scores higher than a test server.

  3. Threat Intelligence

    Boost scores when alert indicators match active threat campaigns, known APT infrastructure, or recently published vulnerabilities.

  4. Behavioral Context

    Factor in whether the associated user or entity has other recent anomalies, creating compound risk scores.

Triage Tip: Train your classification model on analyst verdicts from the past 6-12 months. Include the analyst's reasoning (available in case notes) as features, not just the binary true/false positive label.

Intelligent Routing

Skill-Based Routing

Route alerts to analysts based on expertise. Network alerts go to network specialists; malware alerts go to reverse engineers.

Workload Balancing

AI distributes alerts evenly across the team, accounting for current caseload, shift timing, and analyst availability.

Escalation Logic

Automated escalation when alerts remain unacknowledged or when correlated signals suggest an emerging incident.

Auto-Resolution

Automatically close alerts that match known false positive patterns, with full audit trail for compliance.
