# DataDome

A real-time bot detection platform that analyses every HTTP request using device fingerprinting, behavioural signals, and IP reputation.

DataDome is a real-time bot detection platform deployed as an inline proxy or edge module that inspects every HTTP request passing through it. It collects device fingerprints, analyses behavioural signals from JavaScript sensors embedded in pages, and scores IP reputation to classify traffic as bot or human in real time, typically within 2ms.

DataDome's JavaScript sensor collects detailed browser and device signals — Canvas fingerprints, WebGL renderer, CPU timing, battery status, font metrics, and more — and sends them to DataDome's scoring API. If a request score exceeds a threshold, DataDome blocks with a 403, issues a CAPTCHA (hCaptcha or its own), or silently redirects to a honeypot page.

DataDome is common on e-commerce and media sites. Its sensor update cadence is fast — patches that bypass one version may fail within days. Successfully accessing DataDome-protected sites requires consistent browser-grade fingerprinting at both the network layer (TLS/HTTP2) and the JavaScript layer. AlterLab's Tier 3 full browser rendering includes DataDome-compatible browser signal normalisation.
