What Dotfuscator Does

Dotfuscator is a comprehensive .NET obfuscation and in-app protection solution that secures trade secrets, reduces piracy/counterfeiting, and defends against tampering and unauthorized debugging.

Supported platforms

  • .NET (all versions)
  • Xamarin
  • .NET Core
  • .NET 5+
  • ASP.NET
  • UWP

Key Features

Advanced Protection Technology: Patented obfuscation with method renaming, control flow transformations, string encryption, and metadata stripping provide industry-leading defense against reverse engineering.

Zero-Friction Integration: Integrates directly into your Visual Studio project file (.csproj) on Windows or Mac. One-time setup, automatic protection on every release build.

Detection & Response: Detect tampering, unauthorized debugging, and suspicious activity. Choose custom responses: terminate execution, modify behavior, or trigger alerts.

Smart Compaction & Linking: Reduce app size significantly while consolidating multiple assemblies into a single, easy-to-manage executable. Add watermarking for protecting copyright and other unique information.

Secure Software Development Lifecycle (SSDLC) Support: Supports the complete SSDLC - Agile integration, continuous deployment, debugging support, patch management, and distributed development workflows.

World-Class Support: Backed by PreEmptive's dedicated professional team and comprehensive documentation. 9 of the 10 largest technology suppliers rely on PreEmptive.

Why it matters

Security standards bodies, regulators, and courts recognize app protection as essential for data security. Failing to implement proper protection can lead to increased breach risk, liability, fines, and brand damage.

Microsoft's Choice: PreEmptive has been Microsoft's sole obfuscation provider since Visual Studio 2003 and remains a formal component of Microsoft's internal development process, subject to all of Microsoft's quality, regression, audit, and control gates.
