MonitorDMARC

MonitorDMARC is a free tool for monitoring and analysing DMARC (Domain-based Message Authentication, Reporting and Conformance) records. It helps organisations track email authentication across their domains by processing DMARC reports and displaying practical advice about email delivery, authentication failures, and potential security issues. The tool is designed for email administrators, security teams, and anyone responsible for protecting their organisation's email reputation and preventing spoofing attacks. By centralising DMARC data in one place, it makes it easier to spot trends, diagnose configuration problems, and enforce stricter authentication policies over time.
