FAQ
Common questions
LRDefender helps fraud, product, and engineering teams stop account takeover, payment fraud, bot attacks, multi-accounting, promo abuse, paywall bypass, and more — all with one platform and one API.
We collect 90+ browser, hardware, and behavioral signals — GPU renderer, WebGL pipelines, canvas rendering, audio context, screen properties, and more — to generate a unique, persistent device identifier without cookies.
Yes. Our GPU-level fingerprinting produces a high-confidence match for the same device across Chrome, Firefox, Safari, and Brave — cross-browser identification is a core technical differentiator. Match confidence is reported with every result.
We collect no personally identifiable information. The system is designed for GDPR and CCPA compliance. SOC 2 Type II certification is in progress, and our architecture is ISO 27001 aligned.
Our fingerprinting persists through incognito mode because we use hardware-level signals (GPU, audio context) that don't change between sessions.
The API is built for low latency — fingerprint collection, analysis, and risk scoring run in parallel so the impact on your users stays minimal. Actual response time depends on region, payload size, and the signal set you enable.
Enterprise customers can deploy the entire stack on their own infrastructure. No data ever leaves your network. We support AWS, GCP, Azure, and on-premise.
Free tier includes 10,000 identifications per month. Pro starts at $99/mo with 100K IDs. Enterprise is custom with unlimited volume, dedicated SLA, and on-premise options. No credit card required to start.
