The Declining vendors widget is available on the Trends dashboard (MAX > Customer portal > Trends tab).
This widget lists the vendors with the largest negative change in security score over the last 30 days. Each row shows the vendor's name, its current letter grade and score, and the point decrease over the period, making it easy to spot which vendors in the managed portfolio most urgently warrant a closer look or a proactive check-in before the decline shows up as an escalated finding elsewhere in the portal. Only vendors whose score dropped by a meaningful margin are surfaced.
