When you install a "guaranteed" fraud app, the software provider takes on the risk of chargebacks. To protect their own bottom line, their algorithms are tuned to be hyper-aggressive. If a transaction looks even slightly non-standard, it is declined.
While this lowers your chargeback rate, it creates a secondary problem: The False Positive. Industry data suggests that for every $1 lost to actual fraud, merchants lose $10 to falsely declined orders. This is revenue you already paid to acquire through marketing, now tossed away by a "black box" algorithm.
