// REAL-TIME ALERTS
Real-time SSL certificate alerts
Get paged the moment a certificate enters the danger zone — on the channel your team actually watches.
Staged thresholds at 30 / 14 / 7 / 1 days give you lead time to renew before anything breaks.
Alerts fire on email (Resend), Slack and signed webhooks — wire them straight into your runbooks and incident tooling.
Idempotent delivery means you get one alert per threshold per certificate, never a storm of duplicates.
Certificate Transparency alerts also notify you when a new certificate is issued for your domain.
