DMARC-SRG, a PHP-based solution, provides a comprehensive way to parse, view, and generate summary reports from DMARC aggregate reports. We found it to be quite capable for an open-source tool, offering valuable insights into DMARC compliance, authentication failures, and email sources.

Its strength lies in its ability to be self-hosted, giving us complete control over our data and infrastructure. While it doesn't boast the fancy, modern dashboards of commercial alternatives, it delivers solid, raw data analysis which is crucial for DMARC implementation and monitoring.

The DMARC report viewer, also an open-source project, offers a more streamlined approach to visualizing DMARC aggregate data. It focuses on presenting the essential information in a clear, digestible format, making it easy to quickly grasp DMARC compliance and identify potential issues.

We appreciated its simplicity, which means less complexity to manage when self-hosting. While its feature set might be less extensive than DMARC-SRG, it still effectively highlights critical aspects like source identification and policy enforcement without overwhelming us with too many options.

Using DMARC-SRG requires a bit of technical know-how, particularly with PHP and database setup. The initial configuration involves setting up a web server, PHP, and a MySQL database, which might be a hurdle for those without development experience. Once configured, navigating the interface is straightforward, albeit a bit utilitarian in design.

We found the reporting clear, providing detailed tables and graphs. The user experience is functional rather than flashy, prioritizing data presentation over slick aesthetics. It does exactly what it says on the tin, without any unnecessary frills.

The DMARC report viewer also demands a self-hosted environment, often leveraging Docker for easier deployment. This simplifies the setup process somewhat compared to manual PHP and database configuration, making it a bit more accessible for users comfortable with containerization.

Its interface is clean and intuitive, with a strong focus on visual clarity. We found it easier to quickly interpret the DMARC data thanks to its well-organized layout and simple charts. The user experience here is more polished for an open-source tool, striking a good balance between functionality and ease of use.

As an open-source project, DMARC-SRG primarily relies on community support. We found that the GitHub repository provides a good resource for issues, discussions, and occasional contributions from other users. Direct, dedicated support channels are not available, as expected.

Troubleshooting often involves digging through existing issues or posting new ones and waiting for community input. This can be a slower process than commercial support, but it fosters a self-reliance and deep understanding of the tool for those willing to engage.

Similarly, the DMARC report viewer, being an open-source tool, leans on its community for support. Its GitHub repository serves as the central hub for problem-solving and feature requests. We noticed an active maintainer who is responsive to issues, which is a significant plus for an open-source project.

While there's no official support team, the project's documentation is generally helpful, and the community around it is typically keen to assist. For common issues, solutions are often already documented or readily shared, making the support experience relatively smooth for a free product.

DMARC-SRG is best suited for users who are comfortable with self-hosting, have a solid understanding of web servers and databases, and prefer complete control over their DMARC data. It's an excellent choice for individuals or small to medium-sized businesses (SMBs) with technical staff.

For Managed Service Providers (MSPs) and enterprises, it could serve as a foundational component within a larger, custom-built DMARC monitoring system, provided they have the internal resources for deployment and maintenance. It's not an out-of-the-box solution for multi-tenancy or large-scale, automated deployments.

The DMARC report viewer appeals to users looking for a straightforward, open-source DMARC visualization tool. Its slightly simpler deployment (especially with Docker) makes it a good fit for SMBs or technically savvy individuals who want a quick way to review DMARC reports without extensive setup.

While not inherently designed for large enterprises or MSPs, its modular nature means it could be integrated into existing infrastructure. However, it lacks the advanced features, scalability, and dedicated support typically required for enterprise-grade DMARC management or multi-client MSP environments without significant customization.
