Side-by-side comparison of AI visibility scores, market position, and capabilities
Unit21 is a no-code fraud and AML detection platform enabling financial institutions and fintechs to build and manage transaction monitoring rules without engineering.
About
Unit21 is a fraud and anti-money laundering detection platform that gives financial institutions, fintech companies, and payment processors the ability to build, deploy, and manage transaction monitoring rules and case management workflows without requiring data engineering or infrastructure work for each policy change. The platform's no-code rules engine allows compliance officers and fraud analysts to create detection logic using a visual interface — defining conditions, thresholds, velocity limits, and behavioral patterns that trigger alerts — and deploy those rules to production without waiting in an engineering queue. This self-service capability is transformative for compliance teams at growing fintech companies where the speed of regulatory and fraud threat evolution outpaces the availability of engineering resources to keep monitoring logic current.
