Netcraft DMARC Visualization is a tool that provides visibility and control over DMARC (Domain-based Message Authentication, Reporting, and Conformance) email authentication records. The tool converts technical DMARC reports into visual charts and insights to help organizations identify unauthorized email activity and understand how their domains are being used or exploited. The platform audits existing DMARC records across an organization to show what protections are in place. It validates DNS records to prevent unintended email blocking and provides recommendations for optimizing DMARC and SPF (Sender Policy Framework) records. The tool includes traffic mapping capabilities that allow organizations to see all email traffic associated with their domains. Organizations can use the visualization capabilities to identify which records should be updated to protect specific emails and domains. The tool helps detect criminals attempting to spoof email domains and provides actionable recommendations for email authentication configuration. By providing a complete view of DMARC implementation, the tool enables organizations to tighten security rules while maintaining confidence that legitimate email traffic will not be blocked. The solution is part of Netcraft's broader platform for brand protection and threat detection, which includes capabilities for phishing protection, domain protection, and social media monitoring.
