Turn denied traffic into a decision, not an inbox flood.

What this demo proves

This zero-setup build replays three synthetic outcomes. The target product connects to a Vercel Log Drain once, stays quiet on routine noise, and sends a selective alert that opens this evidence view.

Scope boundary: live ingestion and notification delivery are not implemented in this build.

Connect once

Route a Vercel Log Drain to SignalFence.

Stay quiet

Group routine firewall noise with deterministic code.

Notify with evidence

Open a review only when a cluster warrants attention.

Zero-setup replay

See what stays quiet and what warrants a notification.

Advanced · Analyze a local exportOptional

Use JSON or NDJSON only for local forensics. The file is analyzed in this browser session, is not sent to a SignalFence backend, and raw client IPs are hashed before parsed events reach the UI. Uploaded clusters remain unrated in this build.
