Feature set
Proofpoint Email Fraud Defense offers a comprehensive suite of DMARC-related features, extending far beyond basic reporting. It integrates DMARC deployment with advanced threat protection, including continuous domain discovery to identify lookalike domains and a Virtual Takedown Service for malicious impersonations. This is not just a DMARC tool, it's a full-spectrum brand protection solution.
Beyond DMARC, it provides hosted authentication services for SPF and DKIM, streamlining record management and overcoming common DNS lookup limits. Its integration with Proofpoint's secure email gateway ensures consistent DMARC enforcement on inbound traffic and offers detailed supplier risk visibility, making it a robust, all-in-one platform for email security and authentication.
DMARC-SRG, as an open-source PHP parser, focuses on the core task of processing DMARC aggregate reports. Its feature set is narrow, providing a self-hosted solution for generating summaries and viewing DMARC data. It excels at parsing raw XML reports into a more digestible format, allowing users to understand basic DMARC compliance and authentication results for their domains.
While effective for its intended purpose, DMARC-SRG lacks the advanced capabilities of commercial platforms. It does not offer automated threat intelligence, domain discovery, SPF flattening, or hosted authentication services. Users seeking a no-frills, self-managed DMARC reporting solution with direct access to the underlying data will find it suitable, but it requires manual setup and ongoing maintenance.
