FUGU provides payment fraud prevention technology for online sellers, helping businesses safely accept transactions that might otherwise be lost to fraud, false declines, or payment churn. Its approach analyzes activity before and after checkout, gathering information throughout the transaction lifecycle rather than relying only on payment-stage data. This enables sellers to identify risks such as friendly fraud, improve approval decisions, and reduce exposure to chargebacks.

The platform combines initial risk profiling, payment monitoring, automated identity verification (KYC), risk scoring, and chargeback management. It can assess user sessions, device fingerprints, IP and geolocation data, web interactions, and post-purchase behavior. Suspicious orders can be flagged for additional verification before fulfillment, while collected interaction records can support dispute responses. FUGU also offers a chargeback guarantee to qualifying customers.

FUGU is designed to help merchants increase transaction approvals and reduce operational workload and costs. Integrations are available for Shopify, WooCommerce, VTEX, and Magento, with options for custom setups.
