Replay and Scenario-Based Learning

Experience the Breach. Train for the Real.

Fluency Replay transforms cybersecurity training and validation by allowing analysts and systems to re-experience real events—event by event, packet by packet. With full telemetry timing preserved, Replay brings the reality of detection, investigation, and response to life, creating repeatable, testable learning environments.

Real Event Playback
Replay injects real, timestamp-accurate telemetry into the detection pipeline to simulate past incidents as if they were live.
Scenario-Based Training
Scenarios provide curated, annotated sequences that guide analysts through validation, scoping, response, and hot wash review.
AI & SOAR Validation
Replay tests AI behavior and automation workflows by repeating known incident data and evaluating system responses.
Timing Fidelity
Replay preserves the timing of each event to show how real alerts evolved—and whether detection occurred fast enough.
Detection Tuning
Run known attack sequences through the pipeline to improve rules, enrichments, and thresholds in a repeatable way.
Scientific Repeatability
Replay introduces a testable method for refining detection logic, turning reactive tuning into a structured process.

Training Meets Reality.

Replay enables structured, scenario-based cybersecurity exercises using real, sanitized telemetry. Walk through four investigative stages—validation, scoping, response, and review—to build analyst skill, test detection logic, and tune automation with scientific precision.
