Dregs is fraud detection for SaaS applications. A lightweight JavaScript tracking script fingerprints devices and streams user events; Dregs scores every identity across four dimensions: Humanity (bot and automation detection), Authenticity (fake profiles and disposable emails), Uniqueness (duplicate accounts linked through shared devices, IPs, and sessions), and Behavior (activity compared against expected patterns). Scores are transparent — built from individual analyzer observations you can inspect and tune, not an opaque risk number. Rules raise alerts to the dashboard, email, Slack, or webhooks, and teams adopt in four stages — Scoring, Alerts, Escalation, Autonomy — ending in automated responses like rate limiting and account quarantine. Dregs targets free-trial abuse, promo and referral fraud, duplicate accounts, stolen-card testing, SMS pumping, credential stuffing, and scraping. Setup is self-serve with a free trial and published pricing.
