PreEmptive Solutions' Dotfuscator 4.0 Achieves Immediate Acceptance

Includes first-ever obfuscation tamper notification service, support for Windows Vista and enhanced support for XML serialization and Microsoft .NET Framework 3.0

Cleveland, Ohio - March 8, 2007

PreEmptive Solutions, the leading obfuscation provider for both Microsoft .NET and Java, announced broad market acceptance of Dotfuscator 4.0 only four weeks after its release on Jan. 31, 2007. Dotfuscator 4.0 was released on the same day as Windows Vista, continuing its uninterrupted support for Microsoft infrastructure. "Dotfuscator 4.0 is much more than a compatibility release for Windows Vista," said Gabriel Torok, President of PreEmptive Solutions. "Dotfuscator 4.0 includes significant technology advances including deeper support for .NET Framework 3.0, XML serialization and the much anticipated debut of the Tamper Notification Service."

"We rely upon Dotfuscator to help protect our Intellectual Property and to make our applications more secure," said Tim Reynolds, Sr. Application Architect of the RTL Group. "The RTL Group is focused on consumer oriented banking front end solutions. PreEmptive Solutions' immediate support for Windows Vista combined with the ongoing quality of their software and support have proven to be invaluable as we pursue our own business objectives."

"Dotfuscator 4.0's immediate support for Windows Vista combined with its tight integration with Visual Studio offers one more example of why Visual Studio continues to offer a more secure and highly productive development environment today," said Joe Marini, Director of the VSIP program at Microsoft Corp. "The Tamper Notification Service introduces a powerful detective control helping to protect both .NET application developers and the communities they serve."

Dotfuscator 4.0 can automatically add logic to obfuscated applications to self-diagnose application tampering. For the first time, an obfuscated application that has either been modified or recompiled without authorization will emit secure signals that are assembled into tamper incident reports and distributed in near real-time. Recipients can include both application authors and the consumers' IT staff. The Tamper Notification Service is available immediately to all active Dotfuscator Professional users as part of their standard support agreement and at no additional cost.

"The upgrade to Dotfuscator 4.0 was seamless," said Ken Golding President of CRM Software. "As a company that is focused on office Management solutions for the financial services industry, we are also very interested in exploring the just introduced Tamper Notification Service."

"Acceptance of this latest version of Dotfuscator 4.0 as been remarkable," said Sebastian Holst, senior vice president at PreEmptive Solutions. "In four weeks, we have had over 300 corporations successfully upgrade their development teams and over 40 of those have taken the additional steps required to incorporate the Tamper Notification Service technology into their upcoming production releases."

"The move to Dotfuscator 4.0 was straightforward," said Josh Wagoner, Sr. VP of Engineering, IdentityMine, Inc. "As a company that is focused on creating designer and developer components and tools for Microsoft .NET Framework version 3.0 and Windows Vista Presentation Foundation, we are also very interested in exploring the Tamper Notification Service."

The Tamper Notification Service offers many compelling features including:

• Powerful new IT control: Obfuscated applications can detect and respond to unauthorized modifications by either direct tampering of the executable or the recompilation of modified source code after reverse engineering.

• High value: included in all existing Dotfuscator Professional license and support fees.

• • injection of tamper detection logic creates an agent-free monitoring solution

  • pruning after compilation minimizes, and in some cases eliminates, any change in footprint

• Secure and private: signals are sent via SSL with no personally identifiable information
• No programming required: use of custom attributes to eliminate the need for programming
• Trusted: integrated into and bundled with the most widely installed obfuscation solution today, Dotfuscator 4.0
• Minimal impact on the final application:
