The company (best known publicly for the FICO credit score) that acquired
HNC Software in 2002 and, through Falcon Fraud Manager, now runs
neural-network-based fraud scoring across a large share of the world's card
transactions. FICO's own SEC filings and press releases are the sole
identified source of the "majority"/"two-thirds" reach figure attached to
this infrastructure — the vault found no independent corroboration of it —
which makes FICO simultaneously the operator of a large piece of invisible
financial infrastructure and the only entity that has ever measured its own
reach.
