Phishing, spoofing, and email impersonation attacks continue to rise, damaging brand reputation and putting sensitive data at risk. This is where DMARC and, more specifically, a dmarc checker becomes essential.

It is an email authentication protocol that helps domain owners protect their domains from being used in email spoofing and phishing attacks.

It helps domain owners verify that their DMARC policy is valid, properly published in DNS, and aligned with SPF and DKIM.
