To protect the platform and our users, the following security restrictions are enforced:
| Restriction | Details |
|---|---|
| Allowed ports | Certificate checks only work on ports 443, 8443, 8080, and 80 |
| Private networks | Internal/private IP addresses cannot be monitored (127.x.x.x, 10.x.x.x, 192.168.x.x, etc.) |
| Cloud metadata | Cloud provider metadata endpoints are blocked |
| Webhook URLs | Must use HTTPS and cannot target private IP ranges |
These restrictions prevent abuse and protect both our infrastructure and your networks.
Each plan has limits on certificates, team members, and features. See Pricing for full details.
