Understanding the domain check
Learn what the public domain check tells you and how to read the result.
The domain check is a fast, read-only snapshot of a domain's health. It needs no account and changes nothing.
Step by step
- 1
Enter a domain
Type any domain name into the check on the domain-check page and start the scan.
- 2
Read the SSL result
See whether the certificate is valid, who issued it and when it expires.
- 3
Check DNS and mail
Review nameservers, MX records and whether SPF and DMARC are protecting the domain.
- 4
Act on the risk overview
The summary highlights what to fix first, from an expiring certificate to a missing mail record.
Tip: If the expiry date shows as unknown, the registry simply did not return it — it is not an error.
