DMARC Analyzer


    Protect your brand by stopping direct domain spoofing

    Cybercriminals consistently take advantage of how easy it is to impersonate an organization’s email to dupe their customers, supply chain, and even their own employees. Domain spoofing, where an attacker essentially forges your email to make it look as though their communication has come from a trusted source, is a common tactic used in phishing campaigns and business email compromise (BEC). It’s a big reason why email continues to be the tool of choice for cyber attackers.

    Ignoring this problem can significantly impact your brand reputation, business relationships, and the successful delivery of your own outbound business email. To successfully combat this type of attack you need full visibility into all email senders using your domain to identify legitimate versus fraudulent senders. Enter Domain-based Message Authentication Reporting and Conformance (DMARC).

    DMARC Checker Tools

    DMARC Record Check

    DMARC Record Check is a free and easy-to-use tool that allows you to display your DMARC record, test it, and verify its validity. You can use it to test and lookup your DMARC record, as well as verify and test if your organization is using external domains.

    DKIM Record Check

    DKIM (DomainKeys Identified Mail) is an email authentication technique that allows the receiver to check that an email was indeed sent and authorized by the owner of the sending domain. It works in combination with Mimecast’s DMARC Analyzer solution and with Sender Policy Framework (SPF), enabling you to safeguard email against spoofing, phishing, and impersonation.

    SPF Record Check

    Mimecast’s DMARC Analyzer solution provides an SPF Record Checker to validate your Sender Policy Framework (SPF) record. The SPF Record Checker will validate SPF records on SPF record existence, check multiple SPF records, and more, allowing you to prevent bad actors from impersonating your domains.

    What is DMARC?

    What is DMARC and how does it work?

    DMARC is an email validation system designed to uncover anyone using your domain without authorization, and ultimately block delivery of all unauthenticated mail. It builds on existing SPF and DKIM authentication techniques by adding a critical element, reporting.

    DMARC reports provide detailed information about who is sending email using your domains. Using this information, you can specify what to do when emails fail DMARC authentication checks.
