Same daily dataset, three views: how its mailbox provider is trending, how strict DMARC is at its position in the list, and where its own policy sits among all DMARC publishers in the dataset.

Adoption of the records that go beyond SPF and DMARC. Shown for the whole snapshot — per-domain detail lives on the security posture report.
The same snapshot cut by zone, by list position and by how alive the published policies are.
