Stop risky sessions before they become chargebacks.
Leonix combines device device intelligencee, request-level intelligence, and server-side fraud scoring to help merchants detect suspicious traffic in milliseconds.
Built like a startup product, not a clunky fraud rules engine.
Fast integration, clean architecture, and decision-ready telemetry for checkout, account creation, login, and high-risk account events.
Real-time scoring
Evaluate session risk in milliseconds using request-linked device intelligence and backend decisioning.
Higher signal quality
Use device intelligence, visitor consistency, request telemetry, and server-side validation to reduce blind spots.
Simple integration
Start with one script tag, then expand into APIs, workflows, and tenant-specific policies as you scale.
From browser signal to fraud decision.
Leonix keeps the frontend lightweight while pushing decisioning and validation into your backend stack.
Install one script
Merchants add a single Leonix widget to their site with a tenant key.
<script src="https://cdn.leonix.io/fraudwidgetV1.js" data-tenant-key="YOUR_TENANT_KEY"></script>
Collect trusted signals
The widget loads device intelligencelligence, retrieves visitor and request identifiers, and sends them to Leonix.
Return a decision
Your fraud API evaluates risk, applies rules, and returns allow, review, or block in real time.
Clean domain separation for a modern SaaS stack.
Keep marketing, dashboard, CDN, and decision APIs isolated so the platform stays flexible as you grow.
