What is DMARC?
Security Boulevard, Friday, January 26th, 2024
With the rising volume of fraudulent emails and AI-enhanced phishing scams, industry giants such as Google, Yahoo, and Microsoft have doubled their email security efforts. This shift, in turn, has significantly amplified the demand for email security solutions like DMARC.
What is DMARC? DMARC stands for 'Domain-based Message Authentication, Reporting, and Conformance.' It is an email authentication protocol that helps protect organizations and their email recipients from phishing and spoofing.
DMARC builds on two existing email authentication technologies: Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM). SPF allows a domain owner to specify which mail servers are authorized to send emails on behalf of their domain, while DKIM allows the sender to digitally sign their emails, providing a means for the recipient to verify the message's authenticity.
