Catch every major antidetect browser.
One API. Sub-40 ms.
Antidetect browsers — Kameleo, GoLogin, Multilogin, AdsPower, Dolphin{anty}, Incogniton — generate unique device fingerprints per session and pair with residential proxies to look like real consumers. IP-reputation tools see "clean residential ISP" and let them through. Sentinel sees the tampering signature the antidetect engine can't hide.
How antidetect detection actually works
Every antidetect browser ships with a tampering layer that overrides Chrome's default fingerprinting surface — canvas, WebGL renderer, audio context, font list, hardware concurrency, screen resolution, timezone, language. The point is to make each "profile" look like a different real device.
The catch: spoofing all of those signals consistently is genuinely hard. Real browsers have correlations (a Mac's WebGL renderer maps to specific GPU strings, fonts available depend on OS version, etc.). Antidetect tools cut corners. Sentinel runs a consistency check across 40+ low-entropy signals, and the tampering score lights up when they don't add up.
Combined with the residential-proxy or VPN flag — antidetect browsers are almost never used on residential IPs without a proxy — Sentinel's antidetectBrowser + browserTampering signals catch >95% of fraud-context antidetect sessions in our testing, with sub-0.1% false-positive rate on real consumer traffic.
