Understanding index-level analysis

A stock index groups the largest companies in a market. Analyzing their email security provides a representative snapshot of how a country's or region's corporate sector protects against email-based threats.

What this page shows:

  • Average score - The mean email security score across all constituent companies
  • Grade distribution - How many companies fall into each grade bracket (A+ through F)
  • Company table - Individual scores, grades and key indicator status for each company
  • Sector breakdown - How different industries within the index compare

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?
