Advanced Security Protocols

Newer email security standards show extremely low adoption rates, creating opportunities for early adopters.

MTA-STS (Mail Transfer Agent Strict Transport Security)

Global Adoption0.3%

Despite being a 10x increase from 2021, MTA-STS adoption remains critically low. Over 19.5% of implementations have errors, highlighting the need for better guidance.

DNSSEC (DNS Security Extensions)

Regional Adoption~0%

Analysis shows zero DNSSEC adoption in some regions, leaving domains vulnerable to DNS spoofing and cache poisoning attacks.

The Opportunity

These statistics reveal a massive opportunity for businesses to gain competitive advantage through proper email security implementation. Early adopters of comprehensive DNS security can protect their brand reputation and avoid costly security incidents.
