How to monitor SSL/TLS certificates with CertWatchr: expiry alerts on any port, health scoring, Certificate Transparency, webhooks and the REST API.
Welcome to the CertWatchr docs. Pick a topic on the left, or start with Getting started if this is your first visit.
What CertWatchr does
CertWatchr watches the SSL/TLS certificates on the hostnames you give it and warns you before they expire. It also:
- Gives every certificate a 0–100 health score, so a certificate that is merely "valid" but badly configured is flagged too.
- Watches Certificate Transparency logs and tells you when a new certificate is issued for one of your hostnames, even one you did not issue.
- Notifies you by e-mail or webhook (Slack, Microsoft Teams, or your own endpoint), without repeating the same warning every few hours.
