Domain Health Checker

Check DNS resolution, HTTPS availability, TLS validity, mail routing, and certificate policy in one domain health report.

How to use this tool

Enter a domain and select a quick or full audit. The report combines DNS resolution, HTTPS response, TLS certificate validity, mail routing, CAA policy, source attribution, and an availability-aware health score.

Result transparency

Every report identifies completed data sources, unavailable providers, individual findings, coverage, and detailed evidence. Unavailable checks are excluded from scoring rather than treated as passing.
