Short answer
Less than a do-it-yourself project, but some. FirstNet engineers identify every sending source and specify the SPF and DKIM changes needed, your administrators make those DNS and platform changes under FirstNet's guidance, and FirstNet validates them.
In detail
The split of work:
- FirstNet: domain discovery, DMARC record management, report analysis, source classification, change specifications, enforcement steps, BIMI set-up and monthly reviews
- Your team: making DNS changes and configuring each sending platform, such as Microsoft 365, Google Workspace, marketing tools, ERP and bespoke applications
- Jointly: go or no-go reviews before each move from p=none to p=quarantine to p=reject
The DMARC platform is the easy part. The source authentication work across many systems is what stalls most do-it-yourself projects, and that is where FirstNet's engineers carry the load.
Progress through each enforcement step depends on how quickly your platform owners complete their changes, so having them engaged early keeps the project moving. If work slows, the monthly managed-service review keeps outstanding items visible.
