Every payment evaluated in real time against fraud signals, merchant profiles, and behavioral patterns.

Multi-Channel Scoring
Unified risk scoring across card-present, card-not-present, contactless, and ACH transactions. Channel-specific models with shared behavioral context.
Geo-Anomaly Detection
Location-based fraud signals detect impossible travel, multi-geo velocity, and high-risk jurisdiction transactions. Configurable country risk profiles.
Merchant Profiling
Dynamic merchant risk profiles built from transaction history. MCC-based risk categorization with anomaly detection for compromised merchant patterns.
Velocity Controls
Configurable rate limits per card, per account, and per device fingerprint. Multi-window velocity with rolling aggregation for burst detection.
PCI-Compliant Audit
Every decision produces a signed certificate suitable for PCI DSS evidence. Immutable Merkle-anchored records with configurable retention policies.
3DS & SCA Integration
Seamless integration with 3D Secure and Strong Customer Authentication flows. Risk-based challenge decisions that maximize authorization rates.
