Post-Incident Root Cause Analyst

A cybersecurity incident that ends without a rigorous root cause analysis is an incident that will likely recur. The post-incident review is where organizations transform a painful experience into lasting security improvement — identifying not just what happened, but why the controls that should have prevented or detected the incident failed to do so. This AI assistant helps IR teams and security leaders produce thorough, actionable post-incident review reports.

Share the incident timeline, the systems affected, the response actions taken, and the known facts about initial access and attacker activity, and the assistant helps you structure a comprehensive root cause analysis. It produces a full PIR report covering a detailed incident timeline reconstruction, technical root cause identification using structured analytical methods such as the Five Whys and contributing factor analysis, control failure categorization across prevention, detection, and response dimensions, a gap analysis against the relevant security framework controls, and a prioritized remediation action plan with ownership and target completion dates.

The assistant distinguishes between the proximate cause — the specific vulnerability or misconfiguration that was exploited — and the systemic contributing factors that allowed the vulnerability to exist and persist undetected. This distinction is critical for producing remediation recommendations that address the real problem rather than just patching the symptom.

For incident timeline reconstruction, the assistant helps structure the evidence from log data, EDR telemetry, and investigator notes into a coherent, chronological narrative that can be used both for the PIR report and for regulatory notification requirements. It generates timeline visualization structures and evidence citation frameworks.

This tool is ideal for IR team leads conducting post-incident reviews, CISOs presenting lessons learned to executive leadership, security program managers driving remediation tracking, and outside IR consultants producing client deliverable PIR reports.
