Three steps, a few seconds.
We look up your DNS
Public DNS records, the registry (RDAP) and your mail and web servers. Nothing is installed and nothing is sent to your users.
We score each area
Each area is rated pass, warning or fail, with an overall grade weighted toward the risks that cause real incidents.
You get a priority list
The report puts the most urgent fixes first, with links to the detailed tool for each one.
How long does the health check take?
Usually 10 to 20 seconds. It runs several lookups against public DNS, the domain registry and your servers.
Is the domain health check safe to run?
Yes. It only reads public information, the same information any mail server or browser sees when it connects to you.
Can I check a domain I don't own?
The data is public, so yes, but please use it for domains you manage or are evaluating with permission.
