Anti-Tamper & Obfuscation

What we protect against

Enterprise-grade security layers applied directly to your Android app.

KovSec Shield

Converts your app code to proprietary VM bytecode, making it impossible to read or modify with traditional decompilation tools.

VM Protection

Converts your app code to proprietary VM bytecode, making it impossible to read or modify with traditional decompilation tools.

String Obfuscation

Obfuscates and protects all sensitive text strings in your app, such as tokens, URLs and messages, preventing them from being readable in decompiled code.

Signature Check

Verifies the APK signature matches the original against repackaging

Anti-Hook

Detects and prevents hooking frameworks like Frida, Xposed, LSPosed

Anti-Debug

Prevents dynamic debugging and debugger analysis (IDA Pro, GDB)

Anti-Emulator

Detects emulated environments like BlueStacks, Nox, LDPlayer

Root Detection

Identifies rooted/jailbroken devices at runtime

Library Sentinel

Monitors native libraries loaded in your app process to detect if someone injected malicious libraries attempting to intercept your app behavior.

Memory Shield

Detects when DEX code is loaded directly into memory without a valid APK, a technique used by attackers and tools like Game Guardian to execute code without leaving traces on disk.

Integrity Verifier

Verifies that your native .so libraries have not been modified or replaced with tampered versions that could contain malicious code or backdoors.

Log Sanitizer

Removes all debug calls from your code to prevent sensitive information like tokens, credentials or internal paths from leaking through system logs.

Source Obfuscator

Removes debug metadata like file names, line numbers and local variables, obfuscating your code structure so attackers cannot understand it when decompiling.

DEX Injection Guard

Scans process memory maps to detect DEX files injected from untrusted sources, protecting against attacks that load code at runtime.

Anti-Espionage

Real-Time Attack Detection

Detects and blocks in real-time attempts to spy on your app through screen capture, keyloggers, location spoofing and network interception

Screen Share Guard

Blocks attempts to record or share your app screen, protecting sensitive visual information against capture apps and malicious accessibility services.

Keylogger Defense

Detects keyloggers and accessibility services that attempt to record what the user types inside your app, stealing passwords and personal data.

Fake GPS Shield

Identifies when the device GPS location is being spoofed with mock location apps, preventing your app from being deceived about the user's real position.

VPN / MITM Block

Detects VPN connections and proxies that could be intercepting your app's network traffic to modify requests or steal data in transit.

SSL Pinning Lock

Detects interception certificates installed by tools like Burp Suite or Charles, used to decrypt SSL traffic between your app and servers.

ADB Access Guard

Blocks access to your app via ADB, preventing attackers with USB or remote connection from executing commands on the device and manipulating your application.
