Reducing Your App’s Attack Surface

The rise of hybrid mobile apps

Cross-platform JavaScript frameworks like React Native, Ionic and NativeScript are becoming the standard for companies developing mobile apps.

Attacks targeting JS are growing

Because JavaScript/HTML5 can’t be feasibly encrypted and often has to run on the client-side, it can be targeted by attackers and increase the attack surface.

A key business threat

Exposed JavaScript/HTML5 leads to attacks such as automated abuse, piracy, intellectual property theft and data leakage.

Tamper-Proof Mobile Apps

Protect Your Investment

Protect important algorithms that are vital to your competitive advantage and prevent competitors from retrieving and redistributing them.

Reduce The Attack Surface

Minimize your exposure to data breaches and to attacks that use exposed code as a vector for capturing credentials and sensitive data.

Secure Your Revenue Streams

Prevent attackers from bypassing restrictions or abusing your app to unlock illegitimate benefits that can greatly hurt your business model.

How Jscrambler Protects Mobile Apps

Polymorphic JavaScript Obfuscation

Each time you protect your JavaScript code with Jscrambler, you get a new highly protected version that conceals any important logic while keeping the original functionality.

Runtime Protection

Your application will detect debugging and tampering attempts, derailing execution to prevent attackers from analyzing or modifying your code at runtime

JavaScript Code Locks

You can lock your code to only run in specific domains, OSes, browsers and date ranges. Any lock violation will break the app.


You can trigger automatic reactions to thwart attacks, such as redirecting the attacker, getting a real-time notification or calling a custom function.

Compliant With All the Main
Platforms and Tech Stacks

With Jscrambler, you can protect JavaScript, C/C++, Objective-C/C++, Java, Swift and Kotlin.
