Automatically links users across accounts, devices and IP addresses. ### Network and Device Intelligence More than 100 device and network signals are collected on every visit and cross-checked against each other, which exposes deep masking and delivers 99.9% risk signal detection accuracy. ### Risk Signal Detection VPN, proxy, Tor, Apple Private Relay, datacenter IP, IP reputation, anti-detect browser, browser automation, operating system tampering, incognito mode and geolocation spoofing. Each one is returned as an individual named signal. ### Bot and AI Traffic Detection Identifies bots, automated traffic and AI agents, and separates bad bots from good ones. ### Risk Scoring A risk score from 0 to 100 for the visitor, the user, the device and the IP address. Detected signals, behavioural history, deterministic rules and AI are aggregated into a single normalised score, shown with the signals behind it. Risk bands: Trusted 0-29, Suspicious 30-59, Dangerous 60-100. ### High-Risk Events Four detections that work out of the box, with no fraud model to train and detection rules you can tune for multi-accounting and account sharing. Each carries a Medium or High confidence level, a separate axis from the risk score: - Multi-accounting: one visitor running several accounts - Account sharing: one account used from many devices - Impossible travel: the same account or device appearing in places too far apart for the time between visits - Account takeover: someone other than the owner using a real account ### Traffic Quality Analytics A single traffic quality score plus a score for every source, channel, referrer and UTM campaign, with analytics across visitors, users and devices. ### API, Webhooks and SDKs Visitor IDs, risk scores, named signals and High-Risk Events delivered through the API and webhooks in real time. Client SDKs for JavaScript, React, Next.js, Vue, Angular, Svelte, Preact, WordPress, Shopify and Tilda; server SDKs for Node.js, Python, Go and PHP; an OpenAPI specification for everything else. ## Use cases Protect: - new-account fraud and fake signups - multi-accounting - account takeover - payment fraud - ad fraud and affiliate fraud - bonus, promo and coupon abuse - referral fraud - free-trial abuse - loyalty fraud - ban evasion - sybil attacks in crypto and Web3 - impossible travel and location spoofing - bad bots and abusive AI agents Grow: - returning visitor recognition without a second identity check - account sharing turned into an upgrade conversation - paywall bypass converted into subscriptions - traffic quality: moving budget to the sources that bring real people ## How it works ### 1.
