How this is measured

Tier 0. CAA records at the apex. Denominator: any.

Passive measurement: a single DNS lookup, TLS handshake, or homepage GET per domain. Aggregate-only; no individual company is named. 95% Wilson confidence intervals. Population: domains sampled from the Common Crawl web graph, filtered to those that do email. Parked domains excluded. Snapshot: common-crawl-domain-stratified-c400-g2500-seed20260729.

Why it matters

Without CAA, any public CA may issue a certificate for the domain, so mis-issuance has no technical backstop. Cheap to publish, almost nobody does.
