Why DMARC?

Organizations using DMARC reduce the likelihood that their domain will be used in an attack and are better protected against incoming threats.

DMARC stands for Domain-based Message Authentication, Reporting and Conformance, a mechanism that allows senders and receivers to monitor and improve protection of their domain from fraudulent email. Implementation of DMARC ensures mail recipients can detect when spammers have spoofed the “From” address on mail messages. 


Build a stronger email authentication mechanism for your brand, business, or organization.



Assess your risk with the Domain Security Scanner

The Domain Security Scanner can scan hundreds of domains at one time to allow an organization to better understand, and act upon, the risk imposed on it by its partners who have not implemented DMARC.

Get the scanner so you can better understand what email security protections are in place for your organization and partners.
