Runtime Code Protection & Obfuscation

Protect Your Key Intangible IP Assets Against Reverse Engineering

>70%

of application attacks target the application layer, where business logic and client-side execution are exposed to attackers.

>40%

of all web traffic is impacted by automated attacks, often targeting exposed workflows, pricing logic, and authentication mechanisms.

300%

year-over-year increase in AI-generated or manipulated identity media, accelerating fraud and abuse of automation targeting identity and verification workflows.

Time to Safeguard Your Proprietary Code

Because JavaScript is accessible on user devices, it can be inspected, modified, or copied unless protected, creating a structural exposure that allows attackers to observe, manipulate, or replicate proprietary code and enforcement mechanisms.

Jscrambler Secures Your IP and Application Logic Without Affecting Performance

Runtime JavaScript Protection Against Reverse Engineering & Tampering

Jscrambler uses polymorphic obfuscation and runtime protections to make JavaScript hard to reverse-engineer or tamper with. Protecting AI-generated and vibe-coded scripts, it secures critical algorithms, prevents IP theft, and supports GDPR, CCPA, NIST, and OWASP compliance.

Intellectual Property Protection & Competitive Advantage Preservation

Jscrambler’s obfuscation and runtime protections make JavaScript difficult to inspect or copy, deterring reverse engineering and safeguarding proprietary algorithms in software where IP drives innovation and commercial value.

Software Licensing Enforcement

Jscrambler embeds execution restrictions and anti-tampering into JavaScript, preventing code modification or licensing bypass. Environment checks and real-time alerts help organizations enforce software licensing and protect applications from unauthorized use.

Top Runtime Code Protection & Obfuscation Features

Polymorphic Code Obfuscation

Advanced obfuscation transformations with built-in resilience against all reverse engineering tools and techniques. Its polymorphism ensures that each new build has a different output.

Code Locks

Restrict where and how the code is being executed. Code Locks help to protect code by enforcing licenses and preventing it from running outside of the set parameters, be it Browser, Date, Domain, or Operating System.

Anti-Tampering

Protect your web application against changing or modifying your code. The feature allows for the code to be repaired when that happens or for countermeasures to be deployed. Countermeasures can be specified (optionally) to execute when someone tries to tamper with the code.

Anti-Debugging Protection

Protect your application in runtime and thwart reverse engineering attempts with a powerful anti-debugging feature that detects debuggers in real-time and triggers countermeasures.

Real-Time Alerts

Immediately notice high-risk behaviors and gain real-time reaction capabilities, full application monitoring, and notifications.

Countermeasures

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

Anti-Monkey Patching

Detects when your code is affected by malicious Monkey Patching, code poisoning, and changes in an eval function behavior.

Code Watermarking

Lets you upload JavaScript (or enter a URL) to instantly check for an embedded, near-unremovable watermark that verifies code ownership and aids in IP protection, theft deterrence, and forensic tracing.
