Mimecast DMARC Analyzer is a SaaS-based solution that reduces the cost, complexity and time to implement and manage DMARC in Office 365.
DMARC, or Domain-based Message Authentication, Reporting & Conformance, is a protocol for ensuring that email is sent from legitimate domains. DMARC is one of the most effective ways of protecting against phishing attacks, domain spoofing and other email-based threats.
DMARC builds on the widely used SPF and DKIM protocols for authenticating email. To pass a DMARC check, an email must authenticate with SPF and/or DKIM. Additionally, DMARC requires that all the information about the sender within the message is aligned, which helps to block email where attackers spoof the "From" header of trusted organizations. Finally, the DMARC record stipulates what the recipient of an email should do with the message if authentication fails.
DMARC is an essential tool for organizations using Microsoft Office 365. While DMARC in Office 365 is enabled for inbound emails by default, organizations that use their own domain must manage DMARC monitoring on their own and configure their own DMARC records.
Unfortunately, implementing and managing DMARC in Office 365 is just as complicated as configuring it for any other email provider. Because DMARC builds on SPF and DKIM, email administrators must ensure that their SPF record and DKIM record are up-to-date and properly authorized. Before establishing and enforcing a DMARC policy, administrators must identify all the email senders using their domains, including third-parties legitimately sending email on their behalf. Many organizations have hundreds of domains, including many they aren't aware of. To avoid a situation where legitimate emails fail the DMARC test, organizations often spend months monitoring activity and digesting voluminous and complex DMARC reports before enabling a DMARC reject policy.
There is no native tool for monitoring or managing DMARC in Office 365. For organizations that want to simplify deployment and streamline management of DMARC, Mimecast offers an easy-to-use solution that integrates easily with Office 365.
