Stop risky sessions before they become chargebacks.
Leonix combines device intelligence, IP intelligence, and server-side decisioning to help merchants detect suspicious sessions in milliseconds.
Fraud signals are fragmented.
Merchants often rely on multiple tools for device intelligence, IP intelligence, and behavioral signals. These signals rarely come together in a single decision workflow.
Disconnected signals
Device signals, IP intelligence, and session behavior often live in different systems.
Complex integrations
Engineering teams end up stitching together vendors and custom logic.
Slow decisions
Without a unified engine, fraud decisions become slower and harder to manage.
A simple flow from session intelligence to decision.
Leonix keeps the frontend minimal while moving validation, risk logic, and decisioning into a secure backend workflow.
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 gathers device intelligence, network context, and request-level identifiers, then sends them to Leonix.
Return a decision
Your fraud API evaluates risk and returns allow, review, or block in real time.
Protect critical customer flows.
Leonix helps merchants monitor high-risk moments across the customer lifecycle.
Checkout protection
Detect suspicious sessions before payment authorization and reduce fraudulent transactions.
Account takeover
Identify unusual login patterns and session anomalies linked to compromised accounts.
Promo abuse
Detect coordinated activity across devices and IP ranges targeting promotions.
