How are companies within an index scored?

Each company's primary domain is analyzed for SPF, DKIM, DMARC, BIMI, MTA-STS, DANE/TLSA and DNSSEC. Points are awarded for each standard based on its quality and strictness, totaling up to 100.

What does the grade distribution tell me?

The grade distribution shows the spread of scores across all companies in the index. If most companies score A or A+, the index has strong overall email security. A wide spread from A+ to F indicates significant variation.

Why might a well-known company score poorly?

Email security configuration is often managed independently from other cybersecurity controls. A company may have strong network security but still lack proper DMARC enforcement or MTA-STS deployment.

How often are scores updated?

All domains are rescanned weekly. Changes in DNS records are reflected in the next weekly scan.

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:

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