What is WebGL fingerprinting? How the GPU gives a device away
WebGL fingerprinting identifies a device by how its GPU renders 3D graphics. How it works, what it reveals, and how it differs from canvas.
Pavel Nuryieu is Head of Research at ShieldLabs, where he studies how anti-detect browsers, proxies, and other anonymity tools work, and how detection keeps pace. He has spent close to a decade researching device fingerprinting and online fraud techniques.

What is font fingerprinting? How your installed fonts identify you
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.
What is audio fingerprinting? The browser technique, explained
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.
Residential proxy detection: why home IPs are the hardest to catch, and how detection actually works
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.

Browser fingerprinting identifies a device from 100+ datapoints. Learn how canvas, WebGL, and IP signals work, plus detection methods and countermeasures.
What is canvas fingerprinting? How it works and why it is so stable
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 to detect anti-detect browsers in 2026
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.
