# Vantaj

> Uptime monitoring platform for engineering teams. Monitors websites, APIs, SSL certificates, domains, cron jobs, and status pages.

Vantaj is an uptime monitoring service that checks your websites and APIs from multiple global regions and alerts your team via email, Slack, Discord, or webhooks the moment something goes down. Multi-region consensus prevents false positives — an alert only fires when failure is confirmed from all probe regions.
