Confluent Cloud provides a real-time fraud detection platform built on Apache Kafka and Apache Flink, addressing the three core requirements for production-grade financial systems: security, resilience, and compliance. Security features include TLS encryption, BYOK, client-side field-level encryption (CSFLE), private networking, RBAC, OAuth 2.0, and SAML SSO. Resilience is backed by a 99.99% uptime SLA, multi-availability-zone deployments, and zero-downtime maintenance. Compliance coverage spans PCI DSS, SOC 2, GDPR, CCPA, DORA, FINRA, and other financial regulations. The post walks through a full production architecture covering transaction ingestion, stream processing, ML model scoring, case management, audit trails, and global fraud intelligence via cluster linking.
