Reap, a global financial technology company that enables financial connectivity and access for businesses worldwide through stablecoin-enabled infrastructure, announced the launch of Reap Sentry, a managed card fraud and risk service. Through Sentry, Reap manages a client's end-to-end transaction risk management - from configuring fraudrules and screening authorisations in real time to investigating alerts, processing chargebacks, and reporting confirmed fraud to Visa. Clients do not need to build or license additional fraud-monitoring tools, or hire a dedicated fraud team.

Payment card fraud losses worldwide totalled USD 33.41 billion in 2024 (The Nilson Report, January 2026), tied to global card volume of USD 51.920 trillion (The Nilson Report, January 2026). Every card in circulation is a live payment instrument, with authorisation decisions made in milliseconds. Fraud must be stopped at the point of authorisation, not afterwards, as the knock-on costs of fraud can often exceed the value of the fraud itself. Meanwhile, evolving attack patterns make fraud management an ongoing operational function.

Built on the technology within Reap's issuing portfolio, Sentry combines the fraud policy, tooling, and day-to-day operations required to manage transaction risk effectively. Having issued millions of cards over eight years of card issuance, Reap brings to Sentry controls informed by fraud patterns observed across its entire issuing portfolio. These controls are tailored to each client's business profile, including its cardholder segments, geographic footprint, and stated risk appetite.

Sentry conducts ongoing screening and declines suspected fraud in real time at authorisation; triages and investigates alerts; and continuously updates controls as new threats emerge, including BIN attacks and merchant breaches. The service also processes and represents chargebacks submitted by clients, reports confirmed fraud, and provides program performance reporting on an agreed cadence. Controls are reviewed and refined as each program evolves, without requiring client intervention. Clients can integrate with Sentry through a single Reap API.

Reap protects the authorisation layer it operates and observes, while clients retain responsibility for the cardholder relationship and key first-party fraud entry points, including onboarding, identity verification and account access.

"Most companies launching a card programme have to build a fraud function from day one. Doing so requires specialist tooling, dedicated expertise and several months of preparation before they can safely issue a single card, by which point the threat landscape may already have shifted. That is rarely how a team wants its first months to go." said Harris Leow, Head of Product, Reap. "Sentry takes on that entire card fraud function: our controls, data and specialists, tailored to each card programme."
