Valimail has been tracking the usage of Domain-based Message Authentication, Receiving, and Conformance (DMARC) across tens of millions of domains since early 2017. During that time, we’ve seen consistent growth in DMARC usage and its overall effectiveness.
Now, for the first time, the number of domains with DMARC records exceeds one million.
Download this report to read Key Findings:
1 million+ domains now use DMARC
13.9% overall enforcement effectiveness
30% enforcement rate among Fortune 500 DMARC records
79% of Fortune 500 domains can still be spoofed, because they either have no DMARC, or they are using DMARC in “monitor mode”
75% of U.S. federal domains are protected from spoofing by DMARC enforcement
DMARC usage and enforcement are growing, and are increasingly recommended or mandated by many organizations and governments
