Understand (some) results


p=none or no DMARC

Anybody can create identity theft attacks using your brand name and lead phishing emailing campaigns.

Merox will help you achieve compliance on your domains and protect them. Merox would allow you to bring your domains into compliance so that they are effectively protected.


p=quarantine or warning

You have an active DMARC policy but the receivers' antispams will not drop spoofed emails yet (just quarantine them).

Merox will help you upgrade your domain's protection to "Reject".


p=reject or pass

Your domain is protected from identity theft thanks to a DMARC policy set up to "Reject"

Merox will help you to monitor your DNS entries and alert you in case of any suspicious activity (malicious, shadow IT...).
