About JSDefender

Cutting-edge JavaScript obfuscation techniques with control-flow flattening, tamper detection and other in-app protection transforms. We would not send our own unprotected code to a remote service controlled by third parties and we would not expect you to either. JSDefender supports major JavaScript frameworks, runtimes, and bundlers including Angular, Node, React, React Native, Webpack and others. Unlike languages like .NET and Java that are compiled to intermediate, stack-based assembly instructions before being distributed in binary form, JavaScript apps are typically distributed in source form. This means that your code is directly visible to anyone with access to the execution environment (like a browser). So, potential attackers can very easily step through the running code using a debugger built into their browser, or use other tools to statically analyze the code for vulnerabilities.

BlueClosure

BlueClosure can analyse any codebase written with JavaScript frameworks like Angular.js, jQuery, Meteor.js, React.js and many more. Realtime Dynamic Data Tainting. BlueClosure Detect uses an advanced Javascript Instrumentation engine to understand the code. By leveraging our proprietary technology the BC engine can inspect any code, no matter how obfuscated it is. Scanning Automation. BlueClosure technology can automatically scan an entire website. This is the fastest way to scan and analyse BIG enterprise portals with rich Javascript content as a tester would with his browser. Near-Zero False Positives. Data Validation and Context Awareness makes the use of a dynamic runtime tainting model on strings even more powerful, as it understands if a client side vulnerability is actually exploitable.

Dotfuscator

Application development teams face an ever-growing set of security threats as apps become more central to business and attackers grow in sophistication. These days, intellectual property theft is just the beginning – apps are also gateways to trade secret theft, customer/user data theft, and to identifying further attack vectors. Breaches in any of these areas can cause serious revenue, reputation, and brand damage. Sophisticated app dev organizations know that investing in app protection is good risk management. Basic renaming obfuscation isn’t enough. PreEmptive Protection Dotfuscator for .NET provides many layers of protection: multiple forms of obfuscation (renaming, string encryption, control flow, and more) plus active runtime checks (tamper, debug, root, and more). But it’s not just about protection – we design and test all these layers to be sure that they won’t break your app as the runtime platform evolves.

JavaScript Obfuscator Pro

JavaScript Obfuscator Pro is an advanced code protection platform designed to secure JavaScript against reverse engineering and intellectual property theft. Its flagship VM obfuscation feature transforms readable JavaScript into custom bytecode executed by a proprietary virtual machine. This approach removes standard JavaScript structures entirely, making static analysis and decompilation extremely difficult. Each obfuscation run generates unique bytecode and a custom VM, ensuring no reusable deobfuscation patterns exist. JavaScript Obfuscator Pro supports layered security by combining VM obfuscation with additional protection techniques. The platform works through a simple web interface or API, allowing developers to protect code in just a few steps. JavaScript Obfuscator Pro is built for scenarios where maximum code secrecy is required.
