WebGL fingerprinting identifies a device by how its GPU renders 3D graphics. How it works, what it reveals, and how it differs from canvas.

TLS fingerprinting identifies the software behind a connection from its TLS handshake. How it works, what JA3 and JA4 are, and what it reveals.

Font fingerprinting identifies a device by which fonts are installed, read from how text renders. How it works, what it reveals, and how stable it is.

Audio fingerprinting identifies a device by how it processes a sound signal in the browser. How it works, what it reveals, and how stable it is.

How to prevent multi-accounting: detect one person operating many accounts, why IP-based detection fails, and where detection ends and your decision begins.

WebRTC fingerprinting uses a browser's real-time connection setup to expose network data, including a local or real IP behind a VPN. How it works.

What IP reputation is, how the 0 to 100 score is built, and why a clean IP score alone will not catch fraud. The lagging, shared, and recycled-IP problem.

What JA4 fingerprinting is, how it fixes JA3's weakness to TLS randomization, the JA4 string format and JA4+ suite, and what it can and cannot identify.

How to detect VPNs in 2026: the methods that actually work, why an IP check alone fails, and how masked traffic ties to abuse and risk.

What a residential proxy is, where the home IPs come from, why IP checks miss them, and how residential proxy detection actually works without relying on the address.

What is device fingerprinting: the signals that make up a device fingerprint, how the recognition works across browsers, web vs mobile, and what teams use it for.

Browser fingerprinting identifies a device from 100+ datapoints. Learn how canvas, WebGL, and IP signals work, plus detection methods and countermeasures.

Canvas fingerprinting identifies a browser by how it renders a hidden image. How it works, what it reveals, how stable it is, and its role in fraud detection.

How account sharing detection works: counting the distinct devices behind one login, the signals that reveal it, and how to act without false positives.

The main browser fingerprinting techniques: canvas, WebGL, audio, fonts, TLS (JA3/JA4), and more, what each one reads and how stable it is.

How proxy detection works for fraud prevention: 13 techniques, why residential proxies are hard to spot, and why an IP check alone is never enough.

Anti-detect browsers fake a new device per profile to power multi-accounting. How to detect them: the signals that expose them and why no one check is enough.
