Broadcom adds Arcot Scam Defense to 3-D Secure authentication

Broadcom says reviewing one issuer’s top 1% of successful challenges could have covered about $4 million in a month.

Broadcom launched Arcot Scam Defense, a feature of Arcot by Broadcom meant to flag social-engineering fraud during card-not-present payments after a cardholder completes 3-D Secure. It scores transaction, device, history, and challenge signals, and can use third-party data on whether the authenticating device is on a phone call. Broadcom says nearly half a billion dollars in fraud was reported over 12 months on successfully authenticated challenges. In a one-month pilot, one issuer’s top 1% of successful challenges would have protected an estimated $4 million at a 0.38-point drop in authentication success.

Unconfirmed: The fraud total and pilot savings are Broadcom’s figures from its own testing, not an independent measurement.
