HomeProtection

Layered protection for
compiled .NET assemblies.

DN Shield combines multiple protection techniques so they reinforce each other. Every capability below carries an honest build status — nothing here is presented as finished before it is.

In testingPrototypeIn developmentPlanned

Core obfuscation

The foundation: make decompiled output far harder to read and understand, without changing what the application does.

Identifier renaming

Renames supported classes, methods, fields and properties to less meaningful names, so decompilers reveal structure instead of intent.

In testing

Control-flow obfuscation

Restructures supported method control flow so decompiled output is harder to follow, while preserving the method’s exact behaviour.

In testing

String encryption

Protects selected string literals from straightforward static inspection, recovering them at runtime only when the application needs them.

In testing

Constant protection

Transforms selected numeric constants and supported literals so their direct interpretation is less obvious in decompiled code.

In testing

Code mutation

Applies carefully tested transformations to supported instructions and expressions while preserving the original results. Correctness comes first — nothing ships that is known to introduce errors.

In testing

Application integrity

Protect the shipped assembly itself — its metadata, resources and the integrity of the files you distribute.

Metadata protection

Configurable protection for supported assembly metadata, reducing the structural detail left behind in compiled output.

In testing

Resource protection

Configurable protection for supported embedded application resources.

In testing

Integrity & anti-tampering

Detects certain unauthorized modifications to protected components, making patching and tampering harder while staying compatible with legitimate distribution and updates.

In testing

Anti-debugging protections

Measures that make attaching a debugger to a protected application more difficult. Under active development and hardening.

In development

Advanced protectionEnterprise

Enterprise extends the foundation with DN Shield’s independently developed virtualization engine and a planned application packer — for the logic that matters most.

Custom code virtualization

Translates selected methods into a custom instruction set executed by DN Shield’s own runtime interpreter, rather than leaving them as ordinary CIL. A working prototype exists and is under active development.

Prototype

Attribute-based VM selection

Mark sensitive methods for virtualization with the standard .NET ObfuscationAttribute — no proprietary library reference required in your code.

Prototype

Advanced VM protections

Further hardening of the virtualization runtime and instruction representation. On the roadmap.

Planned

Custom application packer

An independently developed packer for bundling, compressing and protecting application components at distribution time. Planned, not yet built.

Planned

Developer experience

A commercial tool is only useful if it is dependable and clear about what it did. DN Shield is built around reproducible results and transparent reporting.

Windows desktop application

A dedicated Windows app with a straightforward assembly-protection workflow and configurable settings.

In development

Reusable protection profiles

Save and reuse protection configurations for repeatable, consistent builds across releases.

In testing

Detailed protection reports

Clear reporting on what was protected, what was skipped and why. DN Shield never claims a method was protected when it was skipped or failed.

In testing

Output validation & warnings

Reliable output validation plus helpful compatibility warnings and clear error reporting.

In testing

No single technique is a silver bullet. No commercial obfuscator can make software impossible to reverse engineer. DN Shield’s goal is to combine compatible protections so that analysing a protected application takes substantially more effort, expertise and time.
