How Does DMARC work and what is it?

DMARC, or Domain-based Message Authentication Reporting and Conformance, is an email authentication protocol created with the objective of securing business domains and brands from spoofing attacks. 

Attackers can impersonate your organization to send phishing emails to your customers, business partners and even your own employees. Email fraud is one of the most common ways that organizations lose sensitive data and money to cybercriminals. 

DMARC is designed to combat domain spoofing by acting as a way for receiving email servers to check if an incoming message is genuine or not. Let’s understand how exactly it works.
