Windward

Windward analyzes vessel behavior from AIS and related data and flags risk: sanctions exposure, dark activity, identity changes, and other patterns compliance and security teams are paid to notice. It is an intelligence product, not a public ship tracker.

Banks, traders, insurers, and governments use it when a position on a map is not enough and they need a risk opinion on the voyage or the vessel. Pole Star PurpleTRAC is the other name that comes up for sanctions screening. MarineTraffic will show you where the ship is; Windward is for why that movement might be a problem.
