DMARC is a free and open technical specification used to authenticate an email by aligning SPF and DKIM mechanisms. To deploy DMARC, a domain owner publishes a DMARC record in the DNS. dmarcian says that, without domains secured with a DMARC enforcement policy, criminals can pose as a bank or investment firm and send phishing emails to customers. dmarcian says DMARC lets domain owners view who is sending email on their behalf, confirm the legitimate sources and disqualify the rest.[12][14]

The Domain Overview provides a centralized command center for DMARC management across a domain portfolio. dmarcian offers a dashboard that summarizes the authentication status of all domains and email sources and displays the geographical locations of recent abuse attempts. The Detail Viewer is a data discovery DMARC tool for exploring authentication data from multiple perspectives. dmarcian users can investigate specific failed authentication events, trace email paths and receive step-by-step remediation guidance. The Source Viewer consolidates all DMARC-capable email sources across domains and domain groups into a unified management interface.[7]
