The Improving vendors widget is available on the Trends dashboard (MAX > Customer portal > Trends tab).
This widget lists the top 5 vendors with the largest positive 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 increase over the period
Only vendors whose score moved by a meaningful margin are eligible to appear, so a vendor with a flat or negligibly changed score won't show up here even if it's nominally "improving." This gives customers a quick way to see which vendors in their managed portfolio are making the fastest security gains, without having to review each vendor's score history individually.
