TrustedMARC

TrustedMARC is a desktop app that turns the DMARC aggregate report files your mailbox providers send into a single, readable report you can act on.

Save the report files (.zip, .gz or .xml) that arrive at your DMARC address, point TrustedMARC at the folder, and it builds one interactive dashboard: which senders pass or fail SPF and DKIM, who is spoofing your domain, how authentication is trending over time, and the specific DNS changes to make.

It identifies known senders by name instead of leaving you with raw IP addresses, adds geolocation and reverse DNS, checks your live DNS records, and shows all of your domains in one report.

It suits all sorts of user:

In-house IT, and small or medium businesses: keep an eye on your own domains, catch spoofing early, tighten SPF, DKIM and DMARC, and keep a clear record of where things stand. Use it regularly as maintenance or proactive monitoring.

Managed service providers and consultants: the Professional licence covers unlimited domains and commercial use running on up to ten machines, so you can run reports for every client from one tool, with no per-domain or cloud subscription fees.

Individual admins and smaller operators: make sense of the DMARC reports for one or a few domains without learning a platform or signing up to a subscription service.

What sets it apart from the cloud DMARC services is that everything runs on your own machine. You point it at the report files you already receive, nothing is uploaded, there is no third-party server in the loop, and it is a one-time purchase rather than a subscription.
