Understanding country-level analysis

Grouping companies by country reveals how corporate email security practices vary across markets. Countries with stricter regulatory environments or more mature cybersecurity ecosystems tend to show higher average scores.

What this page shows:

  • Average score - The mean email security score across all listed companies in this country
  • Grade distribution - How many companies fall into each grade bracket (A+ through F)
  • DMARC reject rate - The percentage of companies enforcing strict DMARC policies
  • Company table - Individual scores, grades and key indicator status

Key standards tracked

Each company is evaluated on:

  1. SPF - Is the sending policy properly configured? Does it use -all (hard fail)?
  2. DKIM - Are signing keys published and strong enough (2048-bit minimum)?
  3. DMARC - Is a policy in place? Is it set to quarantine or reject?
  4. BIMI - Is the brand logo published for inbox display?
  5. MTA-STS - Is inbound email transport encryption enforced?
  6. DNSSEC - Is the DNS zone signed to prevent spoofing?
