riskr — Real-time fraud detection & identity risk scoring
Intelligent auditing. Weighted precision.
riskr transforms fraud prevention from a static checklist into a high-speed intelligence engine. Three specialized analysis pipelines run in parallel, correlating email, phone, and network signals to identify sophisticated threats in real time.
Rather than relying on simple pass/fail triggers, riskr applies weighted risk points to every suspicious signal — from VOIP detection and geographic divergence to /24 subnet velocity tracking — returning a nuanced, actionable verdict instantly.
