RSDevice Risk Signals

Technical guides

Understand the evidence before using it

Learn what each family of observations can show, what it cannot prove, and how it fits into a production React Native architecture.

Root and jailbreakOpen typed catalog
Transparent by design
  1. Observe exact raw values and outcome states.
  2. Preserve missingness and platform boundaries.
  3. Calibrate on representative physical devices.
  4. Decide only in trusted backend systems.

Root and jailbreak detection

Combine filesystem, package, property, debugger, hook, and runtime observations without producing a client-side verdict.

Emulator and Frida detection

Interpret build markers, virtual hardware, runtime threads, mapped libraries, ports, pipes, and instrumentation artifacts.

Raw signals vs platform attestation

Understand where transparent observations complement Play Integrity, App Attest, and server-side verification.

React Native library comparison

Choose between a raw-signal SDK, focused root checks, runtime protection, or a general device information library.
