Know the device.
Stop the fraud.
A persistent, privacy-safe device and browser identity that links returning users, detects spoofing, and flags anomalies — before a single payment is processed.
70+ signals.
One fingerprint.
Every browser and device emits dozens of stable, measurable characteristics. Serixo collects and hashes them into a single persistent ID — accurate across sessions, IP changes, and incognito mode.
Browser signals
User agent, browser version, installed plugins, language preferences, Do Not Track, cookie support, localStorage, sessionStorage, and IndexedDB availability.
22 signalsHardware signals
Screen resolution, color depth, device pixel ratio, hardware concurrency, device memory, touch points, gyroscope and accelerometer presence.
18 signalsRendering signals
Canvas 2D fingerprint, WebGL renderer and vendor, WebGL extensions, AudioContext fingerprint, and font detection via text metrics.
14 signalsNetwork signals
IP address, ISP, ASN, IP reputation score, VPN and proxy detection, Tor exit node check, datacenter IP flag, and geolocation consistency.
12 signalsBehaviour signals
Mouse movement entropy, keystroke dynamics, scroll patterns, time-on-page distribution, and click target precision — hard to spoof at scale.
9 signalsSession continuity
Cross-session device linkage, return visitor detection, IP delta tracking, device–user binding, and multi-account linkage across fingerprint changes.
8 signalsCollected in 2ms.
Persistent across sessions.
JS snippet loads
A 4kb async snippet fires on page load. It runs in a web worker to avoid blocking the main thread — zero impact on your Core Web Vitals.
Signals collected
70+ browser, hardware, rendering, and network signals are gathered simultaneously. Canvas and WebGL hashes are computed client-side, never raw.
ID computed & linked
Signals are hashed into a stable Device ID and Browser ID. If we've seen this device before, it's linked to prior sessions and known users automatically.
Risk enriches payment
Device trust score, anomaly flags, and session history are attached to every transaction before routing — giving Smart Cascade a richer signal set.
One ID.
Many applications.
Device Fingerprint feeds every other Serixo module — and stands alone as a fraud signal for your own rules engine.
Trusted device fast-track
Skip friction for known devices. When a fingerprint matches a verified user's prior sessions, 3DS2 challenges and manual review are bypassed automatically.
New device login alerts
Instantly detect first-time devices on existing accounts. Trigger step-up authentication or notify the user before the session proceeds.
Multi-account linkage
Catch fraudsters who create multiple accounts from the same device. Fingerprints persist across incognito mode, cookie clears, and VPN changes.
Device risk as a signal
Device trust score, anomaly flags, and session velocity feed directly into Serixo's Risk Scoring engine — adding a stable, hard-to-spoof dimension to every risk decision.
Built for production.
Not just demos.
Tested across 180M+ sessions. Accurate on modern browsers, privacy-hardened devices, and fingerprint-spoofing tools.
