DMARC (Domain-based Message Authentication, Reporting and Conformance) is an email authentication protocol designed to prevent email spoofing. It builds on existing standards like SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) and enables domain owners to define how receiving mail servers should handle unauthenticated messages. DMARC increases transparency through regular reports and helps organizations protect their email communications from phishing, spoofing, and abuse.
DMARC Policy Management: Creating, publishing, and managing DMARC records to define the handling of unauthenticated emails (none, quarantine, reject).
SPF and DKIM Validation: Ensuring that SPF and DKIM records are correctly configured and aligned with the DMARC strategy.
Reporting and Analysis: Automated processing of DMARC aggregate reports (XML) from receiving servers to gain insights into email flows and potential security issues.
Email Traffic Visualization: Graphical display of email origins, authentication results, and policy violations.
Alerts and Notifications: Alerts in case of unusual activity or increased risk due to unauthorized senders.
Forensic Analysis: (optional) Evaluation of detailed individual reports (RUF) to better understand targeted attacks.
Whitelisting and Configuration Assistance: Support in integrating legitimate third-party senders and trusted sources into SPF/DKIM/DMARC.
Compliance Monitoring: Monitoring compliance with internal and external email security requirements.
A financial services provider detects spoofing activity through DMARC reports and updates its policy to "reject."
A company with multiple brand domains uses a centralized DMARC management platform to handle all records and monitor delivery rates.
An IT security officer identifies targeted phishing attempts through forensic DMARC data and takes proactive countermeasures.
An email marketing team ensures that all authorized sending tools are correctly included in SPF and DKIM for optimal deliverability.
