DMARC Expert provides a full suite of DMARC services, extending beyond basic reporting to include active defense mechanisms like technical takedowns of fraudulent domains. We see robust DMARC report analysis, hosted SPF, and hosted BIMI support, simplifying record management significantly.

The platform also incorporates advanced features such as behavior-based anomaly detection (AI-alerts) and IP blacklist (or blocklist) checks, which are crucial for proactive email security. Their DMARC deployment and maintenance services, including expert guidance, are tailored for organizations seeking hands-on support in their DMARC journey.

The Splunk TA-DMARC add-on is primarily an ingestion tool designed to parse DMARC aggregate (RUA) reports and feed them into a Splunk instance. It excels at taking raw XML data and transforming it into a structured format within Splunk, allowing users to leverage Splunk's powerful search and dashboarding capabilities.

However, the add-on itself is quite basic. It doesn't offer native DMARC management features like SPF flattening, hosted BIMI, or active spoof detection beyond what you can configure within Splunk. Its strength lies in its ability to integrate DMARC data into an existing Splunk ecosystem for those who are already heavily invested in Splunk for their security information and event management (SIEM).

DMARC Expert offers a dedicated SaaS DMARC reports analyzer, which means it comes with its own user interface designed specifically for DMARC management. We found it to be intuitive and relatively straightforward, providing a clear overview of DMARC compliance and email authentication sources.

The platform aims to simplify complex DMARC data, making it accessible even for those who are not deep DMARC experts. The inclusion of expert-written action plans directly beneath sending sources in the SaaS platform is a nice touch, guiding users through necessary steps to improve their DMARC posture.

The Splunk TA-DMARC add-on, being an add-on for Splunk, means its user experience is entirely dependent on the underlying Splunk environment. For those familiar with Splunk, it's a seamless extension. However, for users new to Splunk, there's a significant learning curve involved in setting up and configuring the add-on, dashboards, and alerts.

It requires a solid understanding of Splunk Query Language (SPL) and data models to extract meaningful insights from the parsed DMARC reports. While powerful for Splunk veterans, it certainly isn't a plug-and-play solution for DMARC reporting and requires more technical expertise and effort to achieve a similar level of actionable intelligence as a dedicated DMARC platform.

DMARC Expert emphasizes its support, offering various tiers with dedicated Webex sessions and expert consulting. For instance, DMARC Premium includes 2 one-hour support sessions, while Enterprise plans offer 'X' sessions depending on client needs. This direct access to DMARC experts is a significant advantage.

Beyond technical support, they also provide 'DMARC project accelerator' consulting, where a senior DMARC expert guides deployment and strategy. This level of personalized, hands-on support is ideal for organizations that need comprehensive assistance in implementing and managing DMARC.

Support for the Splunk TA-DMARC add-on is, quite frankly, non-existent. The add-on is explicitly listed as 'Not Supported' and 'archived,' meaning there is no official support from the developer, nor should one expect future updates or active development.

Users are entirely on their own for troubleshooting, maintenance, and any custom configurations. While the community might offer some guidance, relying on an unsupported, archived tool for a critical security function like DMARC monitoring can be a significant risk for many organizations. It's a 'use at your own risk' scenario, which can indirectly lead to higher internal costs.

DMARC Expert is highly suitable for organizations of all sizes seeking a comprehensive and supported DMARC solution. For SMBs, the DMARC Premium plan offers a good entry point with expert guidance. Enterprises benefit from the DMARC Enterprise tier, which provides extensive support and continuous surveillance for complex environments with numerous domains and high email volumes.

Managed Service Providers (MSPs) will find the DMARC MSSP tier particularly attractive due to its multi-user management dashboard. Organizations that require active threat neutralization through technical takedown services will also find this platform to be a strong fit, especially those concerned with sophisticated phishing and impersonation attacks.

The Splunk TA-DMARC add-on is best suited for organizations that already have a robust Splunk instance in place and possess the internal expertise to manage and configure Splunk. It's ideal for enterprises with a strong SIEM practice who want to centralize all their security data, including DMARC reports, within Splunk.

It is less suitable for SMBs or MSPs looking for an out-of-the-box DMARC solution, as it lacks a dedicated user interface and direct DMARC management features. Due to its 'Not Supported' and 'archived' status, it's really only for those with the technical resources to maintain an unsupported solution and are comfortable building their own DMARC insights within Splunk.
