Dotfuscator vs. JSDefender vs. ProGuard vs. Python Comparison Chart

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.

ProGuard: Open Source Optimizer for Java and Kotlin. ProGuard is the most popular optimizer for Java bytecode. ProGuard also provides minimal protection against reverse engineering by obfuscating the names of classes, fields and methods. ProGuard reduces the download and startup time of Android applications and improves their performance on mobile devices. ProGuard obfuscates Java applications and pre-verifies the processed code for Java Micro Edition and for Java 6 and higher. ProGuard optimizes and obfuscates Java applications for cell phones, Blu-ray players, set-top boxes and other constrained devices. ProGuard fully supports Java and Kotlin applications, enabling developers to take full advantage of these languages’ features without sacrificing performance or security. ProGuard is a command-line tool with an optional graphical user interface. ProGuard is fast: It processes small Android applications and entire runtime libraries in seconds.
