DMARC Director offers a comprehensive suite of DMARC reporting and management features. We have found its aggregation and visualization of DMARC reports to be very effective, allowing for deep dives into email authentication issues.

It goes beyond basic reporting by including advanced source identification, forensic analysis capabilities, and tools to help implement SPF flattening, which is crucial for larger organizations with many sending services.

DMARC-SRG, as an open-source PHP parser, focuses primarily on parsing, viewing, and summarizing DMARC reports. It provides the essential data needed to understand DMARC compliance, showing aggregate reports in a structured way.

While it lacks the advanced features of commercial platforms, it is very capable for its core function. It processes XML DMARC reports into a readable format, which is invaluable for those preferring a self-hosted solution.

DMARC Director provides a polished and intuitive user interface. The dashboard offers a quick overview of DMARC compliance across domains, with drill-down options that are easy to navigate for detailed analysis.

The setup process is guided, and the platform's features are well-organized. Even users new to DMARC should find it straightforward to get started and interpret the data, making policy enforcement less daunting.

DMARC-SRG's user experience is functional rather than sleek. As a self-hosted tool, installation requires some technical proficiency, including setting up a web server and PHP environment.

Once configured, the interface presents raw and summarized DMARC data in a clear, albeit basic, tabular format. Its simplicity is a double-edged sword: easy to understand for those who know what they're looking for, but lacks the visual aids of commercial tools.

DMARC Director, as a commercial offering, comes with dedicated customer support. We've found their team responsive and knowledgeable, capable of assisting with complex DMARC configurations and troubleshooting.

They offer various channels for support, including phone and email, which is vital for businesses relying on consistent email deliverability. Documentation and onboarding resources are also comprehensive.

Support for DMARC-SRG primarily comes from its open-source community and available documentation on GitHub. This means active, direct support isn't always guaranteed, and users are often responsible for their own troubleshooting.

For those comfortable with self-help and diving into code, the community can be a valuable resource. However, if you require immediate, expert assistance, the open-source model presents a different support paradigm.

DMARC Director is best suited for medium to large enterprises and Managed Service Providers (MSPs) who require a robust, managed DMARC solution with advanced features and dedicated support. Its multi-tenancy capabilities make it a strong contender for MSPs.

SMBs with simpler needs might find it more feature-rich than necessary, but if they anticipate growth or have complex email ecosystems, it provides a scalable foundation for email security.

DMARC-SRG is ideal for technically proficient individuals or small businesses (SMBs) looking for a free, self-hosted DMARC reporting tool. It's excellent for those who value full control over their data and have the resources to manage it internally.

It's less suitable for enterprise or MSPs seeking comprehensive features, automation, or professional support. Its self-hostable nature means MSPs might adopt it as a component within a broader custom solution, but it isn't a standalone multi-tenant platform.
