A domain monitor can cover a domain and its subdomains, or an individual host. It supports two monitoring features, and you can use either or both:
- Monitoring certificates in use: Periodic connections to each monitored host to check the certificates it uses. Hosts can be discovered automatically using Certificate Transparency logs or added manually. Each host counts once, even if multiple ports are monitored.
- Monitoring certificate issuance: Alerts about new certificates in Certificate Transparency logs.
¹ Prices are in USD and do not include tax.
² Alert recipients can receive email or Slack alerts without having a user account.
