OnDMARC offers a robust and comprehensive feature set specifically tailored for DMARC, SPF, and DKIM management. It provides a guided workflow, making it easier to progress from monitoring to full enforcement. Key features include dynamic SPF for overcoming the 10-lookup limit and an "Investigate" tool for instant deliverability diagnostics.
Beyond core DMARC, OnDMARC includes advanced capabilities such as forensic reporting, smart alerts, and an Event Hub for streaming security logs to SIEMs. We appreciate its integrated approach to related email security protocols like BIMI, MTA-STS, and TLS-RPT, alongside tools for blocklists (blacklist) and brand reputation management. For larger organizations, features like DNS Guardian and Radar Pro seats are significant additions.
The Splunk TA-DMARC add-on focuses on ingesting DMARC RUA (aggregate) reports into Splunk. Its primary function is to parse these XML reports and make the data searchable and visualizable within a Splunk environment. This means that while it handles the raw DMARC data, the actual "features" such as analysis, alerting, and reporting are largely dependent on Splunk's native capabilities and the user's expertise in configuring Splunk dashboards and alerts.
Given its archived and unsupported status, the add-on's feature set is essentially static. It lacks advanced DMARC-specific functionalities like dynamic SPF, BIMI management, MTA-STS reporting, or dedicated spoof detection beyond what can be manually configured in Splunk. Its value lies almost entirely in integrating DMARC data into an existing Splunk-centric security operations center (SOC) or SIEM, rather than offering a standalone DMARC management solution.
How easy is each product to use
User experience
OnDMARC generally offers an intuitive and user-friendly dashboard. We found the setup process to be straightforward, with clear workflows and visual reporting that simplifies DMARC management. The platform is designed to guide users, even those new to DMARC, through the complexities of email authentication. Dynamic Services, like SPF and DMARC management, are integrated seamlessly.
However, some users have noted that while the interface is powerful, it can sometimes feel a bit clunky or overwhelming, especially with the sheer volume of daily reports. It might take some time to get familiar with all the options and customize reporting dashboards to avoid information overload. Despite these minor navigation points, the overall experience aims for ease of use.
The user experience for the Splunk TA-DMARC add-on is entirely dictated by one's familiarity with Splunk. It's not a standalone application with its own dedicated UI. Instead, DMARC data becomes another data source within Splunk. For experienced Splunk users, navigating and querying this data is familiar. However, for those without deep Splunk knowledge, the learning curve is steep.
We've observed that users need to build their own dashboards and alerts, requiring a solid understanding of Splunk Search Processing Language (SPL). There's no pre-packaged, guided DMARC journey like a dedicated platform would offer. The archived status also means no new UI improvements or modernizations are being implemented, so what you see in terms of integration with Splunk is what you get, relying heavily on the user to craft their own experience.
Which product has the best support
Support
OnDMARC consistently receives high praise for its support. We've experienced their team to be responsive, knowledgeable, and proactive, with regular check-ins and dedicated account managers for higher tiers. They provide guidance through setup, compliance programming, and offer various channels including email, chat, and phone support, depending on the plan.
Their commitment to customer success is evident in their willingness to assist with complex configurations and resolve issues promptly. While some Express plan limitations exist, the overall sentiment is that OnDMARC's support significantly enhances the user's DMARC journey, making a potentially daunting task much more manageable.
The Splunk TA-DMARC add-on is officially marked as "Not Supported." This means there's no dedicated support team, no official channels for troubleshooting, and no guaranteed bug fixes or updates. When using this add-on, users are effectively on their own, relying on community forums or their internal Splunk expertise to address any issues or configuration challenges.
This lack of formal support is a significant consideration. While the add-on itself is free, the total cost of ownership can increase due to the need for internal resources to maintain and troubleshoot it. For organizations that rely on vendor support for critical security tools, this absence is a major drawback and implies a higher burden on the user's team.
Who should use each product
Suitability
OnDMARC is highly suitable for a broad range of organizations, from SMBs to large enterprises. Its tiered pricing model and feature sets accommodate varying email volumes and security needs. SMBs can benefit from the Express plan's simplicity and core DMARC features, while growing organizations find value in the Essentials plan's expanded capabilities like unlimited SPF and API access.
For enterprises and MSPs, the Premier plan offers advanced features like DNS Guardian, user permissioning, and dedicated support, making it ideal for managing complex, multi-domain environments and providing comprehensive brand protection. Its focus on simplifying DMARC compliance with strong support makes it a strong contender for anyone prioritizing email security and deliverability.
The Splunk TA-DMARC add-on is best suited for organizations that are already heavily invested in Splunk as their primary SIEM or security analytics platform. It's designed to integrate DMARC data into an existing Splunk ecosystem, allowing security teams to correlate DMARC reports with other security events. This makes it a fit for enterprises with mature security operations and dedicated Splunk administrators.
However, it is not suitable for SMBs or MSPs looking for an out-of-the-box DMARC solution, as it requires significant Splunk expertise and lacks the dedicated DMARC management features and support found in specialized platforms. Given its archived and unsupported status, we would generally recommend caution, even for existing Splunk users, unless they have the internal resources and expertise to manage it independently.

Drawbacks and what to watch out for
OnDMARC, while highly effective, sometimes presents a clunky or overwhelming user interface, and its forensic reporting can be difficult to navigate. Splunk TA-DMARC add-on's primary drawback is its archived and unsupported status, meaning no official help or updates, and it requires a separate, costly Splunk instance with significant expertise to manage.

Dynamic SPF and Powerful Features, GUI Could Use Improvement
4.0 / 5
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.

What do you like best about Red Sift OnDMARC?

Securing our domains to bring them up to 100% Reject
