# RASP Protection

Sentinel extends protection beyond initial startup checks by continuously monitoring the application during runtime. Through background scanning mechanisms, it detects unauthorized access attempts, runtime tampering, and external manipulation activities in real time.

```kotlin
sentinel.runtime {
    onCompromised {
        print(msg = "Device integrity failed (Root/Jailbreak detected).")
    }

    onTampered {
        print(msg = "App tampering detected.")
    }

    onHooked {
        print(msg = "Runtime hook detection.")
    }

    onSimulated {
        print(msg = "Running on Emulator/Simulator environment.")
    }

    onDebugged {
        print(msg = "Active debugging session detected.")
    }

    onCritical { score ->
        print(msg = "High risk score reached: $score")
    }

    onSafe {
        print(msg = "All systems nominal.")
    }
}
```
