Replay

Replay is a structured, scenario-based analysis platform designed to simulate real-world cybersecurity events using sanitized or synthetic telemetry. It allows analysts to walk through realistic detection and response workflows in a controlled, repeatable environment. Built on the same infrastructure as live security operations, Replay enables both human analysts and AI systems to evaluate, triage, and respond to security events just as they would in a production setting.

Replay is tightly integrated with Fluency’s security architecture, leveraging HEC-based ingestion, structured workbooks, and AI-assisted analysis. Each scenario is processed through the same event pipeline used in live systems, offering a uniquely authentic and operationally relevant learning and testing experience.

Use Cases

Replay is built to support a range of critical functions within a Security Operations Center (SOC) and cybersecurity development environment:

• Training: Equip SOC analysts with hands-on experience responding to realistic events. Replay provides tiered workbooks that guide users through each phase of the detection and response lifecycle.
• Testing: Validate detection rules, enrichment pipelines, and response logic by replaying known scenarios and confirming expected outcomes.
• AI Evaluation: Benchmark and refine AI assistant workflows by presenting them with consistent, labeled scenarios. Replay helps ensure AI decision-making is measurable, auditable, and aligned with SOC expectations.
• Cyber Range Exercises: Enable red team/blue team simulations or certification programs using real telemetry, allowing for complex multi-phase engagements and post-action review.

Key Benefits

Replay delivers several key advantages to both security teams and platform developers:

• Repeatability: Each scenario can be replayed exactly as it occurred, enabling consistent results across analysts, tools, and training cohorts. This ensures evaluations are fair and outcomes can be reproduced.
• Structure: Replay uses a four-tiered workbook format aligned with SOC workflows, providing clarity and consistency in how events are analyzed, scoped, and responded to.
• Speed: Scenarios can be launched and completed rapidly, offering immediate feedback and analysis results. The platform supports both manual and AI-assisted workflows to accelerate decision-making.
• Realism: Events are replayed as raw telemetry, not summaries or synthetic examples. This creates a realistic environment that reflects the complexity of actual operations, with real log formats, field inconsistencies, and detection challenges.
