Live ## The Global Pulse of email security. Real-time adoption data from actual public domains, benchmarked against our own Top-1M study. Nothing sampled, nothing invented. Global Pulse vs Top-1M study GLOBAL EMAIL SECURITY SCORE – / 100 — Live public data Adoption Radar All 7 protocols · published vs effective How scoring works → Published Effective ADOPTION BY PROTOCOL Baseline: SecLens Top-1M study, Jul 2026 Published = present in DNS. Effective = configured to protect (enforced policy, not decoration). Scoring rules → LAST ASSESSED DOMAINS Assess domain THE CRISIS ## Most of the internet still cannot prove its email is safe. Everyone claims to have SPF and DMARC. The measured reality is far worse — these are the actual numbers. DMARC ENFORCEMENT – % of domains enforce DMARC with p=reject MTA-STS ADOPTION – % of assessed domains have deployed MTA-STS GLOBAL AVERAGE – / 100 security score Only –% score above 70 TRANSPARENT SCORING ## One score. Seven protocols. Zero black box. Every domain gets a 0–100 score built from weighted, RFC-based checks. Domains that legitimately send no mail are scored on a dedicated Null-MX profile instead of being punished for missing mail infrastructure. The assessment engine and scoring methodology are open source, so every rule can be inspected and reproduced.
