Feature set
Cloudflare's DMARC Management is an addition to their extensive suite of internet security and performance services. It integrates into their broader ecosystem, offering DMARC reporting and enforcement alongside CDN, WAF, and DNS solutions. We found its DMARC features to be functional, providing the necessary insights into email authentication results.
However, while Cloudflare provides DMARC, it is one among many services. The DMARC reporting itself is somewhat basic compared to dedicated tools, focusing on aggregation and high-level views rather than deep-dive forensic analysis or granular threat intelligence specifically tailored for email. It's built for those already deeply embedded in the Cloudflare ecosystem.
MailHardener is purpose-built for email security and DMARC. Its feature set is highly focused on DMARC, SPF, and DKIM management, offering detailed reporting, forensic analysis, and guided enforcement. We observed it provides a comprehensive overview of email flows, source detection, and the ability to identify potential spoofing attempts effectively.
Beyond core DMARC, MailHardener also includes features like SPF flattening, hosted DMARC, BIMI, and MTA-STS/TLS-RPT, showing its dedication to all aspects of email authentication. Its detailed dashboards allow for precise policy adjustments and offer strong visibility into legitimate and illegitimate email sources, making DMARC enforcement a more manageable task.
