How this is measured
Tier 1. Validity window of the serving certificate. Denominator: has_web.
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: national company registries (Companies House, Brreg, SIRENE), sampled by size band and resolved to email-active domains. Parked domains excluded. Snapshot: brreg-norway-per600-seed20260730.

Why it matters
The CA/Browser Forum is phasing certificate lifetimes down to 47 days. Any domain still on long-lived certificates has a manual renewal process that is about to break several times a year — a deadline-driven quiet failure that has not fired yet.
