Developed by Breizh Cyber with the support of Afnic and the www.bzh association, DashMARC centralises and analyses DMARC reports and produces dashboards to facilitate configuration error detection and fraudulent use of domain names. DashMARC is an open-source solution that prioritises sovereignty and digital trust.
A comprehensive solution for retrieving, enriching, storing, and visualizing DMARC reports
DMARC (Domain-based Message Authentication, Reporting and Compliance) helps combat domain spoofing via emails thanks to SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) authentication protocols. It provides organisations with reports on outgoing emails from their domains, so as to detect configuration errors and possible fraudulent uses.
But interpreting these reports is not necessarily straightforward. The technical format and the sheer number of reports can make them hard to analyse. Which is where DashMARC comes in: the tool automatically retrieves DMARC reports from email inboxes, analyses them and sets out the results in easy-to-read dashboards. Thus giving your teams an overview of all outgoing email authentication from their domain names. Which means they can easily detect anomalies and seek assistance from sector professionals to correct them.
An open-source solution
Published as an open-source solution, DashMARC gives organisations the possibility to examine how the tool works and adapt it to their needs. They can host the tool on their own infrastructure and use it to analyse their DMARC reports without the need for third-party intervention.
The code, meanwhile, is available on Codeberg, a European community-driven open-source software development hosting platform run by a non-profit organisation, which offers an alternative to major commercial platforms.
And in addition to this autonomy is the expertise of the actors behind the project. Developed by Breizh Cyber with the support of Afnic and the www.bzh association, DashMARC combines the expertise of a regional cybersecurity incident-response centre with that of two non-profits managing domain names and providing holder support.
DashMARC will be presented at the NDDCamp Rennes event on 20 November 2026 at the Carré des Alliés business and conference centre. Breizh Cyber, Afnic and the www.bzh association will be meeting with other sector experts at the event to talk about email authentication, domain name protection and how to combat domain spoofing.
