Dotfuscator Professional 4.1 Extends Tamper Defense and Improves Source Code Protection

Dotfuscator 4.1 sets new standard for enterprise obfuscation with real time tamper response, incremental obfuscation and enhanced obfuscation transformations

Cleveland, Ohio - May 14, 2007

PreEmptive Solutions, the leading obfuscation provider for both .NET and Java, announced the immediate availability of Dotfuscator 4.1. Specific features new in Dotfuscator 4.1 include:

• Real time tamper response: Dotfuscator can inject a developer's own code to execute as a real-time tamper defense rendering tampered applications useless and harmless. Combined with the existing tamper notification service, Dotfuscator effectively eliminates every incentive to tamper with an obfuscated application. This is an enhanced detective IT control.

• Smart incremental obfuscation: Dotfuscator has long been able to generate patches for obfuscated applications and support distributed development groups. Now, Dotfuscator can selectively obfuscate only those components that have been altered within an application while preserving existing dependencies to satellite components. Large applications can be obfuscated in small parts and in parallel and patches can be generated far more efficiently. This is a material improvement to the development process.

• Enhanced obfuscation: Dotfuscator 4.1 includes additional control flow transformations as part of PreEmptive Solutions' continuous security improvements. This is obfuscation technology innovation.

"Enterprise obfuscation is measured in three distinct ways; as a technology to protect against reverse engineering, a development process component to ensure consistent deployment and as an IT control to manage risk," said Bill Leach, CTO of PreEmptive Solutions. "This release demonstrates significant innovation in each of these three areas." 

"Protecting application value and enhancing security is important to many application developers," said Thom Robbins, Director .NET Platform Product Management. "Dotfuscator 4.1 reduces risk associated with reverse engineering and improves efficiency for both developers and their users through their integration with the .NET Framework application development lifecycle."
