Architecture

Standalone Native Security Bridge

AppDefender.dev is a standalone native security layer. React Native is only an integration surface. The Client never implements detection, policy, or KeysDefender.

Client integration

Install: npm install @appdefenderdev/sdk.react-native@1.0.5 or yarn add @appdefenderdev/sdk.react-native@1.0.5 (Bit .npmrc required).

import AppDefender from '@appdefenderdev/sdk.react-native';

AppDefender.initialize({
  appId: 'CLIENT_APP_ID',
  environment: 'production',
  dependencyCallback: (event) => {
    // Coordinate UI only. Native already enforced.
  },
});

const security = await AppDefender.launchSecurityCheck();
if (security.decision === 'BLOCK') {
  // Do not expose protected functionality
}

Public API

The bridge exposes capabilities, not sensors, C/C++ internals, or secure-storage material. Production without the native module fails closed. A callback never overrides BLOCK.
