What Obsidium is
Obsidium protects 32-bit and 64-bit Windows applications and games against reverse engineering, unauthorized changes, and redistribution, with licensing tools for software publishers. It supports native EXE, DLL, and SCR files as well as .NET Framework 4.x executables, and works with Windows XP through Windows 11. Developers can virtualize selected native code into bytecode for a virtual CPU, while licensing options include expiration dates, hardware locking, and code encryption tied to a license. Other protections include integrity checks, encrypted data files, anti-disassembly and anti-debugging measures, and license-key blacklisting. The included SDK has examples for C/C++, Delphi, Rust, C#, Visual Basic, PureBasic, and other languages. A key-generation library is supplied as a Windows DLL and Linux CGI, and Network Licensing can distribute floating-license pools through a local service. The product is paid, has no free plan, and offers a trial; evaluation versions disable several functions, including virtualization and project-file saving. License types include 12 months of updates and technical support.

Who it suits
Obsidium is aimed primarily at software companies offering feature-limited or time-limited evaluations, as well as developers with custom licensing needs. It suits Windows publishers using supported native binary formats or .NET Framework 4.x executables.
Verdict
Obsidium combines binary protection with licensing, trial controls, and network license management for Windows software. Check the evaluation restrictions and Lite license limit against your needs before choosing a license.
