DMARC-SRG is essentially a set of PHP scripts designed for parsing DMARC aggregate XML reports. Its core functionality revolves around processing these raw XML files and presenting the data in a human-readable format, including summaries and detailed views.

While effective for understanding DMARC data, it primarily functions as a local analysis tool. It generates summary reports, but it does not offer advanced features such as real-time alerts, advanced threat intelligence, or policy enforcement beyond what DMARC itself provides. It is a straightforward parser without a sophisticated user interface.

Fraudmarc Community Edition (CE) provides a more structured approach to DMARC reporting. As an open-source platform, it allows users to collect, process, and visualize DMARC aggregate reports, aiming to provide clearer insights into email authentication results.

Fraudmarc CE offers a more integrated reporting environment compared to DMARC-SRG, designed to help users understand their DMARC compliance and potential spoofing attempts. However, advanced features like SPF flattening or MTA-STS, while offered by Fraudmarc's commercial products, are not part of the Community Edition.

Using DMARC-SRG requires a degree of technical proficiency, particularly with PHP and server environments. Users need to install it on a web server, configure cron jobs to process XML reports, and manage the underlying database.

The user interface is functional but basic, focusing on data presentation rather than interactive analysis or sleek design. It serves its purpose for technical users comfortable with command-line tools and direct data interpretation, providing raw insights without much hand-holding.

Fraudmarc Community Edition also demands technical knowledge for installation and ongoing management, as it is a self-hosted, open-source solution. While it aims for clarity in its reports, setup is not a click-and-go process.

The interface for Fraudmarc CE is generally more polished and organized than DMARC-SRG, providing dashboards and visualizations that make DMARC data somewhat easier to digest. However, its self-managed nature means users are responsible for server maintenance and troubleshooting, which can be a significant undertaking.

As an open-source project hosted on GitHub, DMARC-SRG's support primarily comes from its community. Users can find assistance through the project's issue tracker or by consulting the documentation available in the repository.

There is no dedicated support team or official channels for direct assistance. Users should be prepared to troubleshoot issues independently or rely on the collective knowledge of other users who contribute to the project.

Fraudmarc Community Edition offers support exclusively through its community forum. This means users can post questions, share insights, and get help from other users and potentially Fraudmarc developers.

Similar to other open-source projects, there is no direct, one-on-one technical support available for the Community Edition. For dedicated assistance, users would need to consider Fraudmarc's commercial offerings, which include managed solutions.

DMARC-SRG is best suited for individuals or small organizations with strong technical skills that prefer a self-managed, lightweight DMARC reporting solution. It is ideal for those who want to understand the raw DMARC data without extensive graphical interfaces.

It is less suitable for MSPs, enterprise, or SMBs looking for a polished, full-featured DMARC monitoring platform with automated alerts, advanced analytics, or multi-tenancy capabilities. Its hands-on nature makes it perfect for developers and system administrators.

Fraudmarc Community Edition targets advanced users and organizations comfortable with self-hosting and managing their own DMARC infrastructure. It is a good fit for technically proficient SMBs or even smaller enterprises who want a free, open-source alternative for DMARC reporting.

While offering more structured reports than DMARC-SRG, it may not be robust enough for MSPs managing many clients or large enterprises needing scalable, managed solutions, and features like a multi-tenancy or a dedicated support. It is a strong choice for those who value control and transparency of an open-source solution.
