The Vendors by grade widget is on the Status dashboard (MAX > Customer portal > Status tab).
This widget shows a snapshot of the current distribution of your vendors' SecurityScorecard letter grades (A through F), broken out by MAX tier (Platinum, Gold, Silver). Unlike Security Rating Over Time, which plots that same A–F distribution across the last 12 months to show a trend, this widget shows only the latest scoring date, so it answers "where does my portfolio stand right now," not "how did it get here."
Grades are computed from each vendor's current total score (A = 90+, B = 80–89, C = 70–79, D = 60–69, F = below 60), and a vendor with no tier assignment is grouped under "unknown" rather than dropped from the count.
