What it is
JScrambler
JScrambler is the leading JavaScript code protection platform. It combines advanced obfuscation, anti-tampering, and RASP (Runtime Application Self-Protection) to ensure that client-side code cannot be read, copied, or manipulated. Essential for financial applications, e-commerce, and any system with business logic exposed in the browser.
Transforms JavaScript code into an unreadable, functionally equivalent version, impossible to reverse even with automatic deobfuscators.
Anti-tampering and self-defense
Detects and reacts to any attempt to modify the code at runtime, injecting defensive code that renders the app unusable if tampered with.
RASP: Runtime Application Self-Protection
Monitors application behavior in real time, detecting and blocking attacks such as malicious script injection and hooking.
Mobile protection (React Native)
Protects React Native and JavaScript mobile applications against reverse engineering on Android and iOS.
Evernow + JScrambler
From licensing to operations, all in one partner
As a certified partner, Evernow goes beyond reselling the license. We conduct the proof of concept, implement, train your team, and operate the platform with defined SLAs.
POC & Assessment
We apply JScrambler protection to a client build and demonstrate the before/after difference, with performance impact analysis.
Implementation & CI/CD Integration
JScrambler integration into the build pipeline, protection policy configuration, and functional regression testing.
Training
Training for the frontend team to configure and maintain protection policies as the code evolves.
Integrity Monitoring
Configuration and monitoring of tampering attempt alerts detected in production.
Technical Support
Support for obfuscation fine-tuning, performance impact analysis, and resolving incompatibilities with frameworks.
The average impact is 2-5% in execution time, acceptable for the vast majority of applications. Evernow runs performance tests as part of the implementation to ensure the client's thresholds are respected.
Yes. JScrambler has a specific protection module against bots, web scrapers, and malicious automations that abuse client-side APIs.
Yes. JScrambler supports all modern JavaScript frameworks, such as React, Angular, Vue, Next.js, and Nuxt, with integration via webpack, Vite, and CLI.
