Get a report for any domain
We check its website, certificate, DNS, and registration in one go, then tell you what needs attention. Add a page address to check that page too.
What the report covers
- The domain
- Who it’s registered with, when the registration expires, and whether email is set up: mail servers, SPF, and DMARC.
- The website
- Whether the certificate is valid and when it expires, whether DNS resolvers agree, and whether the site loads.
- A page (optional)
- Enter a full address, such as
example.com/pricing, and we also check that page’s response and redirects, and audit it for search if you ask.
