How can DMARC reports be enriched with user-level data for better domain enforcement?

Summary

Enriching DMARC reports with user-level data is crucial for improved domain enforcement. This involves integrating various data sources, including ESPs, ISPs, CRM systems, marketing automation platforms, user feedback loops, geolocation data, threat intelligence feeds, deliverability testing tools, and reputation data. These integrations aim to identify individual user behavior, track email engagement, detect anomalies, prevent phishing attacks, and improve email security. Tools like Google Postmaster Tools, Microsoft ATP, and Cisco's email security products enhance this process, but challenges remain in obtaining user-domain mapping, data availability, and ensuring data privacy.

Key findings

  • Data Integration is Key: Integrating DMARC data with multiple external sources (CRM, threat feeds, etc.) provides a more complete picture.
  • User Feedback is Valuable: Feedback loops and complaint reports help identify specific user-related deliverability issues.
  • Threat Intelligence Enhances Security: Combining DMARC with threat intelligence and SIEM systems enables proactive threat detection.
  • Enhanced Domain Enforcement: Geolocation data, reputation data, and deliverability testing tools aid in identifying suspicious activity and improving email placement.
  • Vendor Specific Solutions Exist: Tools like Microsoft ATP and Cisco offer built-in enrichment and analysis capabilities.

Key considerations

  • Data Availability and Accuracy: Access to reliable user-level data from various sources is essential, but data availability may vary.
  • Integration Complexity: Integrating diverse data sources and systems can be technically challenging and require significant effort.
  • Data Privacy and Compliance: Handling user-level data requires strict adherence to privacy regulations and implementation of appropriate security measures.
  • Cost of Implementation: Implementing and maintaining enriched DMARC reporting systems can incur significant costs.
  • Addressing the User-Domain Gap: Standard DMARC reports lack user-domain mapping, necessitating additional data sources or solutions to bridge this gap.

What the experts say
3Expert opinions

Enriching DMARC reports with user-level data can be achieved by using feedback loops (FBLs) to identify and suppress users who mark emails as spam. Integrating internal data, like CRM or help desk information, can connect authentication failures to specific user accounts, facilitating targeted remediation. However, the fundamental challenge lies in obtaining user-domain mapping since standard DMARC reports lack this data, highlighting the need for external data sources or integration methods.

Key opinions

  • Feedback Loops: FBLs are a key mechanism for identifying users who mark emails as spam, allowing for their suppression and improvement of sender reputation.
  • Internal Data Integration: Integrating CRM and help desk data enables connecting authentication failures with specific customer accounts for targeted remediation.
  • Data Source Challenge: Standard DMARC reports lack user-domain mapping, necessitating the use of external data sources or alternative integration methods to enrich the reports.

Key considerations

  • Data Availability: Access to reliable feedback loops and comprehensive internal data is crucial for effective DMARC enrichment.
  • Integration Complexity: Integrating internal data with DMARC reports can be technically complex and require significant effort.
  • User Privacy: Handling user-level data requires careful consideration of privacy regulations and the implementation of appropriate data protection measures.
