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.
Mimecast provides a cloud-based service that includes a suite of solutions for email security, archiving and continuity that help to simplify management of business email and reduce the cost and complexity of protecting email data from attackers.
At the center of Mimecast email security offerings is the Mimecast Secure Email Gateway. Combining sophisticated threat intelligence and multilayered detection engines, this Mimecast service provides DNS authentication services that include SPF, DKIM and DMARC protocols to prevent spoofing and impersonation. In conjunction with DMARC Analyzer, a new Mimecast alliance partner, Mimecast provides 360-degree email channel visibility, reporting and validation that provides organizations with insight into any unauthorized use of their domain, allowing them to reject illegitimate emails more quickly and with greater confidence.
In addition to DMARC-based authentication, Mimecast provides a suite of services that helps to protect against other types of sophisticated techniques used in ransomware, spear-phishing and impersonation attacks. These include protection against:
