protection_layers
Six layers. Stacked where they matter.
Instead of relying on a single tactic, DN Shield combines practical protection layers that work together. Apply selectively per assembly, per module, or per method.
01
anti_debug--runtime
Detect debugger attachment and frustrate runtime inspection. Reduces easy step-through analysis of sensitive code paths in production builds.
02
control_flow--mutate
Restructure execution paths with opaque predicates and misleading branches. Recovered code reads as fragmented logic instead of clean intent.
03
string_encryption--all
Encrypt URLs, configuration values, license keys, and internal messages. Plaintext literals are no longer exposed in straightforward decompiles.
04
renaming--aggressive
Rename types, methods, properties, parameters, events, and fields. Strips meaningful naming that lets reverse engineers move quickly through your assembly.
05
code_mutation--pattern
Transform sensitive logic into more complex equivalent patterns. Resists predictable signatures and routine pattern-matching recovery.
06
virtualization--vm + anti-vm
Custom virtualized execution for higher-value routines, plus detection of sandbox and VM environments commonly used for analysis.
use_cases
Made for the .NET apps teams actually ship.
A practical fit for commercial desktop apps, internal line-of-business tools, public-facing .NET utilities, and anything carrying licensing logic or IP you don't want exposed.
partner_builds.cs
Harden partner deployments
Ship builds to customer or contractor environments with stronger resistance to casual analysis and tampering.
analysis_cost.cs
Raise the analysis cost
Make inspection noisier, slower, and less useful when someone starts pulling apart your assemblies.
supported_targets
Built for shipped .NET applications.
Compatible with the runtime stacks .NET developers actually ship — from internal WinForms tools to public-facing ASP.NET services.
- WinForms — line-of-business apps and desktop utilities
- WPF — modern desktop UIs and customer-facing products
- ASP.NET — web apps, APIs, and internal services
- Services — background workers and dependency-heavy builds
deployment_flow
Direct path from trial to shipped build.
Evaluation, purchase, customer delivery, and renewal all sit beside each other. No extra systems to wire up just to let buyers try, pay, and pull their builds.
- HWID-locked 7-day trial for evaluation
- Single license at $300 — direct purchase, no enterprise overhead
- Customer download flow via UID + registered email
- License extensions for ongoing updates and priority support
install --trial
Start with the trial. Ship a protected build today.
The 7-day trial is HWID-locked and intended for evaluation. Move to a paid license when you're ready to ship protected releases to customers.
