Naiza is an API-first fraud prevention and AML screening platform for banks, fintechs, payment providers, and other digital businesses. Its REST API evaluates events such as logins, registrations, payments, and withdrawals, returning ALLOW, REVIEW, or BLOCK decisions with risk scores and rule context. Teams can configure rules, use device signals and IP or email enrichment, and manage allowlists and blocklists. The platform also provides sanctions, politically exposed person, and watchlist screening for individuals and entities, with match details routed into review workflows. A web dashboard supports event monitoring, investigations, team access, and case handling; AML workflows include event monitoring and SAR record creation. Naiza offers API and browser-SDK integration options and is hosted in Saudi Arabia. It is intended for product and risk teams integrating fraud decisions and screening into customer onboarding and transaction flows.
