As cyber threats continue to evolve, there's no denying that businesses must prioritize email security to protect their data and assets. One effective solution for combating email spoofing and phishing attacks is DMARC (Domain-based Message Authentication, Reporting, and Conformance). Choosing the right DMARC analyzer can be expensive and complicated, but an open-source solution might be just what your organization needs. In this blog post, we will delve into the world of open-source DMARC analyzers.

What is DMARC, and Why is it Important?
DMARC is an email authentication protocol that uses both SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to ascertain whether an email has been sent legitimately and aligns with the domain owner's policies. It helps organizations battle email spoofing and phishing by allowing them to publish their email authentication practices and request actions for non-compliant emails.
