FAQ
It checks the domain's registration info (WHOIS), DNS and resolution, email security (MX/SPF/DKIM/DMARC), HTTPS/TLS and website availability, then scores it with a fixed rule set.
The score comes from a deterministic rule engine on the server: the same probe results always produce the same score, so it is reproducible and auditable. AI only explains the findings and never changes the score.
S Excellent (95-100), A Very good (85-94), B Good (70-84), C Fair (55-69), D Poor (40-54), F Critical (0-39). An unreachable site, missing HTTPS or an invalid certificate caps the grade.
No. AI only writes the overall summary and recommendations; if it is not configured or fails, the report still shows the score and per-dimension details.
A domain's report is cached for 7 days so repeat lookups are instant. Cache hits do not consume your quota; try again later for a fresh result.
To control resource usage, each IP can generate 3 new reports per day. Cache hits are not limited.
