🇳🇱 AEX Email Security

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

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?
