Lumen overview

Lumen is TrustData's anomaly triage agent. It answers one question: can I trust my data?

When something breaks — a pixel stops firing, a GTM publish silently removes a tag, a Shopify theme deploy wipes your checkout tracking — Lumen detects it, investigates automatically, and tells you exactly what went wrong, when it started, and what to fix.

What Lumen monitors

How it works

Timeline with annotations

The main view is a timeline with two annotation tracks overlaid on your existing charts:

• Top track — anomalies detected by Lumen (conversion drops, tracking gaps, config changes)
• Bottom track — known changes (GTM publishes, Shopify deploys, budget shifts, manual notes)

When a conversion drop aligns with a GTM publish on the timeline, you have your answer without opening a single investigation. Click any marker to see details, or open the activity panel for a searchable, filterable feed of everything that happened.

Investigations

When Lumen detects an anomaly it can't explain from context alone, it opens an investigation. Each investigation shows:

• Verdict — what broke, severity, when it started, and estimated impact
• Evidence trail — each check Lumen ran and what it found
• Recommended fix — what to do next, with a confirm / false positive / escalate action

Status on existing screens

Lumen surfaces health signals without adding new pages:

• Health indicator on the client list (agency view) so problems appear at a glance
• Status badge on the property overview showing last scan result
• GA4 audit findings surfaced as warnings in the integrations area

Availability

Lumen is included from the Measure plan (€149/mo) on the full TrustData platform.

Standalone plans are available for teams that only need observability:
