Top-scoring websites

A high aggregate score across CheckFast's 19-check audit means a site has its fundamentals locked in: a valid, unexpired TLS chain with no mixed-content warnings, a DMARC policy at p=reject with aligned SPF and DKIM, clean DNS with no dangling CNAME records, an SEO configuration that passes current best-practice audits, social metadata that renders correctly, and enough supporting signals to publish the score as a report, badge, status-page widget, or monitoring baseline.

Scores are normalised to a 0–100 scale per tool, then averaged across every tool that has returned a result for that domain. Only public check rows with persisted scores are included — domains that have been checked but returned no numeric result (e.g. a tool error or timeout) are excluded from the average. This keeps the leaderboard honest: a site can only appear here if it has been successfully audited by at least one tool in the CheckFast corpus.

Green (80+) reflects no critical findings across every audited tool. The top domains on this list tend to be infrastructure-focused companies, major SaaS vendors and security-conscious open-source projects — they invest heavily in technical hygiene because their reputation depends on it. Amber (50–79) usually means one actionable finding. Red (under 50) means multiple tools returned critical results.

Scores here are based on the most recent public check per (domain, tool) pair in the corpus. The corpus grows as CheckFast's crawler runs and as users run public checks via the site health tool. If a domain you care about is missing, running a public check will add it within the next hourly revalidation cycle.
