ILVeil layers managed VM protection, generated native runtime variants, IL obfuscation, runtime guards and release verification into one desktop workflow. Application Guard can bind licensed features to derived values, execution checkpoints and encrypted resources for software that needs more than a single feature flag.
Unmodified assembly, or a freshly published project.
Symbols renamed, strings encrypted, control flow reshaped.
Selected methods become custom bytecode behind protected dispatch.
Anti-debug and integrity checks watch startup and chosen paths.
Post-protection checks confirm the build still runs.
Use the layers that match your application. Unsupported methods fall back safely instead of being transformed blindly.
Selected methods become custom bytecode behind protected dispatch. High-value static methods can also use a generated native runtime variant with deployment-bound key material.
String encryption, symbol renaming, control-flow transforms and integer masking work as coordinated layers, not one trick.
Anti-debug and integrity checks can guard startup and selected execution paths, each with an explicit response policy.
Checks, application records and logs confirm the release still runs — not just that it was transformed.
Guard does not scan or understand your business logic automatically. You choose what values, checkpoints and resources a signed capability can unlock. Starter SDK and License Issuer are bundled — see what's included.
No client-side protector makes your code impossible to reverse. ILVeil is designed to multiply analysis cost, remove easy bypass points, and preserve application behavior across every layer.
ILVeil is intended for Windows .NET software vendors protecting licensing logic, proprietary algorithms, desktop applications, game clients and Native AOT releases. Requires the .NET 9 Desktop Runtime.
