May 31st, 2016 | By Pedro Fortuna | 2 min read

We have released our latest version, Jscrambler 4.0!

It is a breakthrough for JavaScript Security. You will notice many improvements, from our interface to our transformations, to ensure the integrity of your JavaScript applications is always protected and that the users' experience is never compromised.

We hope you like all of it and give us your feedback!

Untraceable Protection

Our team of JavaScript security experts has gone further to ensure any attempt to attack or reverse your application is unfeasible.

With Jscrambler 4.0, all transformations work together to ensure your applications' code is transformed into a distinct and obfuscated version with each protection.

Every time it runs, your code will take up a new form so that no traces are left behind by potential attackers.

New cutting-edge transformations

We added 18 new transformations to our list of unique others already available and that makes Jscrambler the only solution that is capable of actually protecting your JavaScript application.

Special mentions to the possibility of making your control flow completely flat and the new option of hiding all the regular expressions on your code. Two incredibly resilient techniques, among many others, will make your application inscrutable.

Application Management & Creation

Jscrambler 4.0 was developed to meet the needs of the application developer, be it web, mobile, node.js, or others. Thus, a switch to an app-centric platform was a clear path for us. Easily creating your app, swiftly managing its different versions, effectively protecting it, and deploying it with the assurance that your business is as safe as possible – those were our goals and we guarantee you’ll enjoy the experience.

Even more developer-friendly

The new Jscrambler Protection Platform was thought and designed to give the ultimate experience for developers wanting to choose the ideal protection features for their JavaScript Applications. The new Side-to-Side tool allows you to have a preview of the original and the transformed code at all times, making it easier to understand the resilience and potency of every applied transformation.

The choice of transformations and where you apply them is also more straightforward. You can pick each target you want to transform, be it strings, classes, functions, you name it, and see the effects on your code in real time.

Protect when you want, where you want

Jscrambler 4.0 brings yet another enhancement to an existent feature – Ignore Code Blocks – that will bring even more flexibility and control to the process of fine-tuning the set of transformations that will protect your app.

From now on it will be possible to change the transformations’ behavior using code annotations (a.k.a. code comments), namely allowing to:

  • Enable/disable a transformation

  • Change transformation parameters

  • Change transformation order
