Email Authentication Made Simpler

DMARC is a trusted solution that brings together email authentication protocols, and adds reporting and compliance. In just a few easy steps, you can get started with DMARC today to protect your organization from email fraud.

What is DMARC?

DMARC stands for Domain-based Message Authentication, Reporting and Conformance. It’s like an identity check for your organization’s domain name. A DMARC policy allows a sender to indicate that their messages are protected, and tells a receiver what to do if one of the authentication methods passes or fails – either send the message or reject the message to junk. Further, DMARC helps prevent the sending of fraudulent email using your organization’s domain.
