How it works

From session to decision in milliseconds.

Leonix keeps the frontend minimal while moving all risk logic into a secure backend workflow.

Install one script

Drop the Leonix widget into your page with your tenant key. No SDK, no build step, no configuration.

<script
  src="https://cdn.leonix.io/fraudwidgetV1.js"
  data-tenant-key="YOUR_KEY"
  data-api-base="https://...">
</script>

Signals collected automatically

The widget gathers device fingerprint, IP intelligence, VPN/proxy status, bot signals, and network context — then calls the Leonix API in the background.

Act on the decision

Leonix returns allow, review, or block with a risk score and reasons. React to it on your page — or let the widget handle it silently.
