Protect and Secure your .NET Code
Dotfuscator is a .NET Obfuscator & much more. It provides enterprise-grade app protection, greatly reducing the risk of piracy, intellectual property theft and tampering. Our layered obfuscation, encryption, watermarking, auto-expiry, anti-debug, anti-tampering and alerting and defense technology provides protection for hundreds of thousands of applications around the world.
How easy is it to Decompile .NET apps?
All .NET applications and libraries are compiled to Microsoft Intermediate Language (MSIL). MSIL maintains high-level information about your code including its structure and class, field, method, property and parameter names. With a free decompiler, it is very easy to recreate the source code. Obfuscation and related techniques can make it much more difficult for a hacker or competitor to reverse-engineer your application.
Why use a .NET Obfuscator?
By making a .NET application much more difficult to reverse-engineer, you can help protect against intellectual property (trade secret) theft, bypassing licensing or other access checks, and searching for vulnerabilities.
How does Obfuscation and Code Protection Work?
Various different techniques that complement each other are used to create a layered defense to make reverse engineering, tampering, debugging much more difficult.
Some examples include:
- Rename Obfuscation
- String Encryption
- Control Flow Obfuscation
- Unused Code and Metadata Removal
- Binary Linking/Merging
- Dummy Code Insertion
- Instruction Pattern Transformation
- Opaque Predicate Insertion
- Anti-Tamper Wrapping
- Anti-Debug Wrapping
- Security Alerts
- Custom Response to Tamper or Debugging

Why should you protect your .NET code against debugging?
Whether a hacker is trying to steal your data, pirate your app, or modify the behavior of a critical piece of software as part of a larger crime – a production debugger is the hacker’s weapon of choice. You should not make it easy for them.
