Preventionlabs checks your website from the outside in about 15 seconds, from one click, and gives you one report: problems first, each with the evidence and the fix.
It checks pages from your sitemap (failing, slow, redirecting or hidden from Google), .env/.git/backup files anyone can download, outdated scripts with published security holes, security headers and CSP, HTTPS and redirects, SPF/DKIM/DMARC, DNSSEC, nameservers, dangling DNS records, domain expiry, and WordPress and Shopify versions visible from outside. It also checks uptime every 5 minutes and emails you when a site goes down and when it's back.
Read-only: nothing on your site, DNS, code or settings is changed. Only a site's verified owner can check it, by DNS TXT record or a Cloudflare account. No AI: reports are produced by code from the data checked.
