Fraud losses and false-decline losses are both expensive, and most businesses only find out their monitoring is broken after a fraud spike shows up in a chargeback report or a wave of legitimate customers complain about being blocked. Building this well means real-time transaction scoring tuned to your actual fraud patterns, not a generic ruleset that either lets too much through or blocks too many good customers.
A fraud ring found the gap and it wasn't caught until the chargebacks arrived
A pattern of fraudulent transactions went through undetected for weeks because there was no real-time scoring, only after-the-fact review. By the time chargebacks started arriving, the losses and processor penalties were already locked in.
Legitimate customers get blocked by overly aggressive fraud rules
A rigid, generic ruleset flags real customers as fraud risks and blocks their purchase, and there's no easy path for them to get unblocked. Support spends more time reversing false positives than the fraud rules actually prevent in losses.
There's no visibility into why a transaction was flagged or cleared
The fraud decision is a black box, so when a flagged transaction turns out to be legitimate — or a cleared one turns out to be fraud — there's no audit trail explaining what signals drove the decision. Tuning the system means guessing instead of adjusting based on data.
What you get.
Real-time transaction scoring
Transactions scored at the moment of purchase using signals like velocity, device fingerprinting, location mismatch, and behavioral patterns, flagging risk before the charge completes rather than after.
Configurable rule engine tuned to your fraud patterns
Rules built around your actual historical fraud data rather than generic industry defaults, so the system catches your real risk patterns without over-blocking normal customer behavior.
Manual review queue for borderline cases
Transactions that fall into an ambiguous risk range route to a review queue with the context needed to make a fast, informed decision, instead of an automatic block or automatic approval.
Full decision audit trail
Every flag, clear, or block is logged with the signals that drove the decision, so the system can be tuned based on outcomes and disputes have a defensible record behind them.
Chargeback and dispute data feedback loop
Outcomes from chargebacks and disputes feed back into the scoring model, so the system improves over time instead of running on a static ruleset that goes stale.
Integration with your existing payment stack
Monitoring plugs into your checkout and payment processor flow without requiring a separate fraud platform migration, keeping the customer experience unchanged for legitimate transactions.

Frequently asked.
Both are options — integrating and tuning an existing service like Stripe Radar or Sift is usually faster and cost-effective, while a fully custom scoring engine makes sense when your fraud patterns are specific enough that off-the-shelf rules don't fit well.
