a real check of the things an attacker looks at first: the certificate, the redirect, the security headers, what the server gives away and what wordpress leaves open. no signup, no report pretending to be advice.
certificate & https: is the certificate valid, how long is left, and does http actually redirect to https.
security headers: hsts, content-security-policy, x-frame-options, x-content-type-options, referrer-policy, permissions-policy.
what the server tells: server and x-powered-by headers that hand an attacker your exact software versions.
wordpress exposure: visible version, open xmlrpc.php, readable readme.html, a public user list.
mixed content: http:// files loaded on an https page — the padlock lies and the browser blocks parts of the site.
php that no longer gets fixes: the version behind the site, and whether it still receives security patches at all.
most sites are not chosen — they are found by a bot that tries thousands of addresses a minute, looking for exactly these signals. an old version, an open endpoint, a missing header. the fix is boring and cheap; the clean-up after is neither.
