    Protecting email data with DMARC.

    Domain-based Message Authentication, Reporting and Conformance (DMARC) is protocol for email authentication that helps an organization to prevent cyber criminals from illegitimately using its domain name to initiate email spoofing or impersonation attacks.

    What is DMARC designed to do? The DMARC email security standard enables senders to indicate that email originating from their domain is protected by SPF and/or DKIM, and provides instructions for how receivers should treat messages that don't pass either of these authentication methods. Consequently, DMARC minimizes the impact of fraudulent or harmful messages for recipients while protecting the integrity of the sender's domain. DMARC also enables recipient organizations to inform sender's about email that passes or fails DMARC compliance.

    However, DMARC alone cannot protect an organization from a wider range of malware-less impersonation attacks – it only addresses illegitimate use of a legitimate domain name, and attackers frequently use slightly different domain names that appear almost identical to the original, which DMARC cannot stop. That's why, when seeking the strongest levels of email data protection, more organizations today are turning to solutions from Mimecast that combine DMARC with a multilayered approach to stopping an email data breach.
