Grade A — 3 minor.
passive scan · the deep checks need you signed in · scanned 3h ago
This is a passive website security report for www.whiteui.store, graded A (94/100). We checked its SSL certificate, HTTP security headers, DNS records, email spoofing protection and publicly exposed files — the same surface a browser and a search engine already see.
We found 3 issues on this scan — each has a plain-English explanation and a copy-paste fix below.
Not your site?
Without `X-Content-Type-Options: nosniff`, browsers may guess ("sniff") the type of a response and, for example, run an uploaded file as JavaScript. It's a one-line header that closes a whole class of content-type confusion bugs.
whiteui.store is not protected by DNSSEC. DNSSEC signs your DNS records so resolvers can detect a forged answer — without it, an attacker who can poison DNS could point your domain at their own server without touching anything you control.
whiteui.store publishes no CAA records. CAA tells the world which certificate authorities are allowed to issue HTTPS certificates for your domain. Without it, any CA can be persuaded to issue a cert for your domain, which widens the door to mis-issuance.
