Original data on how the world's businesses protect their domains — from our ongoing census of 262 million+ graded domains. Free to read and cite. Data as of 2026-06-27.

Across every dataset below, 86.3% of domains score grade F — effectively unprotected against email spoofing. Only 0.5% reach a secure A–B grade.

• Domain Security by Country
  We graded the business domains behind 100 countries' national domain endings. Here is how exposed each country is — to email spoofing and insecure websites — ranked from least to most exposed.
• Domain Security by Industry
  Using industry-specific domain endings as a proxy for sector, we ranked 15 industries by how exposed their domains are. The pattern holds across all of them.
• The Most & Least Secure Domain Endings (TLDs)
  Of the larger domain endings we grade, which protect their businesses best — and which leave them most exposed? Here are the extremes, from the 112 TLDs with enough graded domains to compare fairly.
• The State of Domain Security 2026
  Our flagship narrative report from the census.
• The Domain Security World Cup 🏆
  Just for fun: if the trophy went to the safest domains, who would lift it?
