 The phrase chargeback insurance is also sometimes used to describe the guarantee provided by online fraud prevention companies such as Vesta, ClearSale, Forter, Riskified and Signifyd.Unlike with card present transactions, where the merchant is not liable for the cost of fraudulent transactions (unless they do not meet technological security requirements such as EMV), merchants are liable for card not present transactions which turn out to be fraudulent.For this reason, online fraud prevention companies who offer decisions (meaning, they provide an approve or decline decision for orders) rather than scores (where the merchant must themselves decide whether to approve or decline) sometimes offer to cover the cost of the chargeback, since the chargeback would not have occurred had their decision not been incorrect.
