Security Architecture

How Modern Bot Fingerprinting Works

Automated scrapers and compliance crawlers try to simulate real humans, but they leave distinct programmatic anomalies across browser APIs.

navigator.webdriver

Automation Flags

Headless browsers controlled via Selenium, Puppeteer, or Playwright expose webdriver bindings and automated CDP hooks.

WebGL Acceleration

Hardware Emulation

Cloud servers lack physical GPUs, falling back to SwiftShader virtual software rendering that immediately flags crawler farms.

Display Geometry

Screen & Color Depth

Automated scripts often render with 0x0 display buffers or missing outer dimensions, exposing non-interactive headless windows.

TLS Fingerprints

JA3 / JA4 Tokens

Python requests, cURL, and bot frameworks negotiate SSL ciphers in distinct sequences different from genuine mobile/desktop browsers.

Frequently asked questions

Technical inquiries regarding bot detection algorithms, automated crawlers, and campaign protection.

How does this Bot Checker detect automated browsers?

The Bot Checker inspects client-side automation indicators including navigator.webdriver, missing Chrome runtime plugins, automated screen dimensions, WebGL vendor masking, broken canvas hashes, and known ad review crawler User-Agents.

Why is AI bot filtering critical for performance marketing campaigns?

Ad review bots from Meta, Google, TikTok, and spy scrapers continuously scan landing pages to ban accounts or steal high-converting funnels. Cloaker.net filters these automated crawlers with sub-15ms edge precision, redirecting them to safe compliance pages.

Can advanced headless browsers bypass basic JavaScript detection?

Basic scripts can be bypassed by Puppeteer-stealth or modified Playwright instances. Cloaker.net uses multi-layered machine-learning fingerprinting, TLS JA3/JA4 token checks, and ASN datacenter filtering to catch even customized headless crawlers.

Can spy tools (like AdPlexity or SpyOver) be blocked with this?

Yes. Spy tools rely on datacenter scrapers and emulated browser pools. Cloaker.net detects and redirects spy tool scrapers to mock safe pages, keeping your high-performing funnels and angles private.
