Security Ingrained in the Source Code

Conceal Code Secrets and Sensitive Data

Using resilient obfuscation techniques and a polymorphic behavior, Jscrambler Code Integrity conceals the whole logic of your source code and prevents static analysis.

Enforce Secure Environments

Jscrambler Code Integrity provides a series of Code Locks that enable you to restrict app execution to trusted environments, such as specific browsers, OSes, or non-rooted/jailbroken devices.

Mitigate Attacks at Runtime

Jscrambler Code Integrity provides self-defensive capabilities that allow you to thwart any attempts to debug or tamper with your app in real-time and ensure the integrity of your code.

How Jscrambler shields your 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.
