OnDMARC is a robust, feature-rich DMARC reporting and management platform. It offers extensive DMARC report analysis, detailed source detection, and sophisticated spoof detection capabilities. A key strength is its 'Dynamic Services' feature, which helps manage SPF, DKIM, and DMARC records, including SPF flattening to overcome the 10-lookup limit.
Beyond core DMARC, OnDMARC provides advanced tools like forensic reporting, an API for integration, smart alerts, and an 'Event Hub' for streaming security logs to SIEM systems. It also supports BIMI, MTA-STS, TLS-RPT, and includes brand protection features such as 'Radar' and 'DNS Guardian' for blocklist (or blacklist) and reputation monitoring. This makes it a comprehensive suite for email security.
DMARC-SRG, as an open-source PHP tool, focuses on the fundamental aspects of DMARC report parsing, viewing, and summary generation. It provides basic DMARC report analysis, allowing users to see aggregate data and identify sending sources based on the XML reports. The core functionality revolves around processing the raw DMARC data into a more readable format.
Due to its open-source nature, DMARC-SRG lacks many of the advanced features found in commercial solutions. It does not offer proactive spoof detection beyond what's inherent in DMARC reports, nor does it include SPF flattening, hosted DMARC, BIMI support, or blocklist monitoring. Its feature set is primarily a foundational DMARC report viewer rather than a comprehensive email security platform.
How easy is each product to use

User experience

Logo
DMARC-SRG
First comparison imageSecond comparison image
OnDMARC aims for an intuitive and user-friendly experience with its web-based dashboard and guided workflows. Users generally find it easy to set up and navigate, with clear visual reporting to help understand DMARC compliance. It simplifies complex tasks like DMARC enforcement and SPF record management, which can be daunting manually.
However, some users report the GUI can be a bit clunky or overwhelming initially due to the sheer volume of data and options. While we appreciate the depth, the learning curve can be steep for those new to DMARC. Once familiar, though, the single-pane-of-glass interface becomes a significant asset for ongoing management.
DMARC-SRG, being a self-hosted PHP script, requires a more hands-on approach for setup and daily use. Installing and configuring it involves command-line operations and web server management, which will be second nature to some, but a challenge for others. The user interface, when set up, is functional but basic, focusing on displaying parsed DMARC data rather than interactive dashboards.
Its user experience is primarily for technically proficient individuals or teams who prefer to maintain their own infrastructure and have full control over their data. It lacks the polish and automated guidance of commercial platforms, requiring users to understand the underlying DMARC concepts and how to interact with the tool directly via scripts or a rudimentary web interface.
Which product has the best support

Support

Logo
DMARC-SRG
First comparison imageSecond comparison image
OnDMARC is highly regarded for its excellent and responsive customer support. They offer various channels, including email, chat, and phone support, depending on the plan. Users often highlight the knowledge and helpfulness of their technical staff and dedicated account managers.
The platform provides an annual or quarterly account review, compliance programming, and custom SLAs for higher tiers. This extensive support infrastructure makes OnDMARC a reliable partner, especially when navigating complex DMARC implementation and enforcement challenges.
As an open-source project, DMARC-SRG does not come with official dedicated customer support. Users rely on community forums, GitHub issues, and self-help documentation available in the repository. This model is typical for open-source tools.
While a knowledgeable community might exist, it's not a guaranteed, direct support channel. Organizations considering DMARC-SRG should have in-house expertise or be comfortable with troubleshooting issues independently, as there's no service level agreement (SLA) or direct assistance provided.

Suitability

OnDMARC is well-suited for a broad range of organizations looking for a managed, comprehensive DMARC solution. For MSPs (managed service providers), its multi-tenancy capabilities and user permissioning are beneficial. Enterprise organizations will appreciate its advanced features, scalability, dedicated support, and SAML/SSO integration.
Small and mid-sized businesses (SMBs) can also benefit, particularly with the Express plan, which offers core DMARC features without the full complexity. It's ideal for those who prefer a hands-off approach to DMARC management, valuing ease of use, strong support, and advanced email security protection without needing deep technical expertise for daily operations.
DMARC-SRG is best for technical users, developers, or organizations with in-house IT expertise who prefer an open-source solution. It's particularly suitable for those who prioritize cost savings and have the resources to self-host and maintain the tool. This includes small businesses with a dedicated tech team or individual enthusiasts.
It is generally less suitable for MSPs or enterprise environments that require extensive features, scalability, professional support, or advanced reporting beyond basic DMARC aggregation. Without a robust feature set and professional support, it's not designed for environments needing comprehensive email security automation or advanced threat intelligence.

Drawbacks and what to watch out for

When examining potential downsides, OnDMARC, despite its comprehensive features, sometimes faces criticism regarding its user interface, which can be perceived as clunky or overwhelming by some users. We've also noted mentions of limited customization for certain reports. DMARC-SRG, on the other hand, comes with the inherent drawbacks of an open-source tool: a lack of official support, a steeper technical learning curve for setup and maintenance, and a far more basic feature set that requires manual effort for many aspects.

Dynamic SPF and Powerful Features, GUI Could Use Improvement
What do you like best about Red Sift OnDMARC? I have been using Red Sift OnDMARC for over three years for monitoring DMARC, SPF, and DKIM across multiple domains, which would be difficult to manage without such a tool. It offers the ease of dynamic SPF and dynamic DMARC, which simplify complex monitoring tasks. The software provides a powerful set of features, making any initial setup challenges worthwhile. I especially value the single pane of glass interface as an IT administrator managing domains that engineers use, allowing me to track domain usage, detect spam issues, and dynamically update DMARC, DKIM, and SPF with ease. The dynamic SPF and DMARC/DKIM reports are integral for my operations, as they save considerable time by turning potentially lengthy tasks into several-minute jobs. Furthermore, the friendliness and support from our account manager, alongside our quarterly meetings, enhance the overall experience and decision to continue using the platform. What do you dislike about Red Sift OnDMARC? I find the GUI a little bit difficult to navigate sometimes and a bit clunky, which sometimes makes it hard to find what I want. What problems is Red Sift OnDMARC solving and how is that benefiting you? I use the product to monitor DMARC, SPF, and DKIM across domains, simplifying updates and detecting spam issues with ease. It turns lengthy tasks into minutes, providing a comprehensive view of domain usage and security.

Easy DMARC implementation with great visibility
What do you like best about Red Sift OnDMARC? OnDMARC makes it very easy to set up and maintain DMARC records. The guided workflows and clear reporting helped us move from monitoring to full enforcement confidently. The user interface is intuitive, and support is very responsive whenever we have questions. What do you dislike about Red Sift OnDMARC? It would be helpful if some of the reporting dashboards allowed more customization or export options. Sometimes, the volume of daily reports can feel overwhelming without filtering. What problems is Red Sift OnDMARC solving and how is that benefiting you? It is helping us prevent domain spoofing and phishing attacks by enforcing DMARC policies. It has also improved visibility into who is sending emails on behalf of our domain, so we can take quick action if needed. Overall, it has strengthened our email security posture and improved trust in our communications.

It is quite a useful tool to manage SPF/DKIM/DMARC records and understand it's impact on the domain.
What do you like best about Red Sift OnDMARC? The ease of using the application and the UI that is provides that helps in managing the records of the domain. Plus the customer service for the tool is quite responsive. What do you dislike about Red Sift OnDMARC? The limitation of the feature of MTA-STS, in which it reports only a few of the domains. What problems is Red Sift OnDMARC solving and how is that benefiting you? It helps us in getting a clearer picture of the use case of our domain, plus the acceptance and the rejection rate.

Easy DMARC setup
What do you like best about Red Sift OnDMARC? We have had OnDMARC for several years, we onboarded all of our managed domains over the past 12months. It was very easy adding SPF, DKIM records and moving DMARC to 100% Reject. We had support from Red Sift all the way. What do you dislike about Red Sift OnDMARC? Sometimes the dashboard is misleading, i had moved a domain to reject 50% and the dashboard didn't reflect that. but customer support fixed that very quickly What problems is Red Sift OnDMARC solving and how is that benefiting you? Securing our domains to bring them up to 100% Reject
