Solution · Decision support

Help investigators see the cases that deserve a closer look, and why.

Models and rules score each transaction, claim or application for risk and explain which signals drove the score. High-risk items go to an investigator's queue with the evidence assembled. People make the decision; the system helps them prioritize.

Who uses it

The workflow

Fraud, risk and compliance analysts who review alerts and cases, and the operations teams whose transactions, claims or onboarding decisions depend on them.

Today
  • Static rules produce so many alerts that analysts cannot review them all properly.
  • New fraud patterns are found months later, in losses or chargebacks.
  • Analysts rebuild the same evidence from several systems for every case.
  • Outcomes of investigations are not fed back, so the rules never improve.
  1. Collect event and context data

    System

    Transactions, claims or applications are joined with account history, device, network and reference data as they arrive.

  2. Score and explain

    AI

    Models and rules produce a risk score and the top contributing signals for each item.

  3. Prioritize the queue

    System

    Items above agreed thresholds enter the investigation queue, ordered by risk and value, with evidence and related cases attached.

  4. Investigate and decide

    Person

    An analyst reviews the case, gathers anything else needed and decides the outcome — clear, hold, request information or escalate.

  5. Feed back outcomes

    System

    Confirmed outcomes are recorded and used to retrain models and tune thresholds on a regular schedule.

What to measure

Where people stay in control

The system does not decline customers, deny claims or close accounts on its own. It ranks and explains; trained analysts decide, and their decisions are recorded with reasons. Thresholds, model changes and any automatic holds are approved by the risk owner, and model performance and fairness are reviewed on a set schedule.

  • Confirmed fraud found per alert reviewed
  • Share of confirmed cases that were flagged before loss
  • False positive rate and its effect on legitimate customers
  • Analyst time per case

Data and integrations

  • Historical transactions, claims or applications with confirmed outcomes
  • Account, customer and device data available at decision time
  • Existing rules and alert history
  • Case management system access for queueing and feedback

Realistic boundaries

  • Scores support decisions; adverse actions against customers remain human decisions made under your policies.
  • Models need labeled outcomes to learn; where confirmed cases are few, rules and anomaly detection carry more weight.
  • Features are reviewed for proxies of protected characteristics, and explanations are kept for audit and regulatory review.

Questions buyers ask

Not unless you decide it should, for specific cases with clear evidence and an approved policy. By default it prioritizes and explains, and investigators make the call. Any automatic hold is designed with a fast path to human review.

Each score comes with the signals that contributed most, in plain terms, and the model version and data used are logged. See our AI governance work for documentation and review practices.
