Threatmetrix assigns a fraud risk/score based on multiple factors, including the geolocation, IP, & browser. Additionally (to your point #1), they anonymize data across their customers and alert if a device has been flagged in a fraudulent transaction elsewhere. On top of their own customers, they partner with Cybersource so there is quite a network of data behind their fraud analysis.

(I don't work for Threatmetrix- but I do use their product as provided via Cybersource.)

Hey Tom -- I'd love to see if we could help with fraud even above and beyond what Cybersource/TM do. Feel free to e-mail me: [e-mail]!
