Everything you need to trust your data
Built for analytics and data teams who rely on GA4 events for business decisions.
BigQuery native
Connects directly to your GA4 BigQuery export. Your data never leaves your own GCP project — we just read it.
Smart alerts
Get notified via Slack or email the moment an event drops below your threshold — before your team notices.
Daily automated runs
Set your schedule once. Signal Guard checks your GA4 data every day at the hour you choose, no manual work needed.
Event filtering
Focus on what matters. Use allowlists to monitor only key events like purchases, or denylists to ignore noisy debug events.
Your GCP, your billing
BigQuery costs are billed to your own Google Cloud account. We never see or store your raw analytics data.
Full run history
Every check is logged. Drill into any past run to see which events were affected, by how much, and when.
Instant alerts, zero noise
When something breaks, you'll know exactly what, by how much, and since when.
