Global mandates and guidance for DMARC 2024

For cybersecurity, email security and IT teams, understanding and adhering to global DMARC (Domain-based Message Authentication, Reporting, and Conformance) requirements is imperative. 

At Red Sift, we have put together a tabulated overview of DMARC mandates and guidance enforced across different regions worldwide. Our aim is to provide a clear, unambiguous guide that consolidates the varying global requirements into one accessible format. 

Whether you are an IT security professional, email administrator, or a compliance officer, this table will serve as an essential tool to ensure your organization’s email security aligns with international best practices and requirements.
