Incogniton Detection

How to detect Incogniton in 2026

Incogniton offers a free tier that draws lower-skill fraud operators and amateur scrapers. Higher absolute volume than the premium tools, lower per-session sophistication. Often paired with rotating cheap-pool proxies rather than premium residential exits.

Detection signals that fire on Incogniton

Sentinel runs a consistency check across 40+ low-entropy fingerprint signals on every evaluation. The signals below are the ones that, in our internal testing, fire most reliably on fresh Incogniton profiles paired with residential proxies. None alone is diagnostic — the combination is.

Plugin-stack inconsistency

Incogniton's default plugin array doesn't match the version Chrome ships for the claimed UA.

Screen resolution vs UA

Common Incogniton profile generators pair desktop UAs with mobile-typical screen resolutions (375×812, 414×896) without DPR adjustment.

Cheap-pool proxy correlation

Incogniton's default proxy integration lists cheap pool providers — the IP characteristics differ from premium residential.

Outdated Chromium engine

Free-tier Incogniton lags 2–3 Chromium major versions behind real Chrome — but reports the latest UA.

Time-of-day clustering

Free-tier user base shows characteristic regional time-of-day patterns indicating workflow farms.

Behavioural simplicity

Inter-action timing is too uniform — real users vary, scripted Incogniton sessions don't.

Incogniton's free tier (10 profiles) drives the majority of its volume. Detection rate >97% on Incogniton given the engine-version mismatch alone.

How to integrate

Embed the Sentinel SDK on your signup, login, or checkout page. Server-side, call /v1/evaluate with the SDK token. The response includes device.antidetect (boolean) and device.tampering_score (0–1). Block, step-up, or score on the result.

See the API reference for the full request/response shape and the 2026 antidetect detection deep-dive for the underlying technique.
