Deviare is a professional hooking engine for instrumenting arbitrary Win32 functions, COM objects, and functions which symbols are located in program databases (PDBs). It can intercept unmanaged code in 32-bit and 64-bit applications. It is implemented as a COM component, so it can be integrated with all the programming languages which support COM, such as C/C++, VB, C#, Delphi, and Python.

Several Fortune 500 companies are using Deviare technology for application virtualization, packaging, and troubleshooting, and for computer security. Computer science researchers are also using Deviare to conduct malware and reverse engineering studies. Our blog articles contain a vast quantity of code samples to get you started easily.

Deviare offers a unique programmer friendly API which resolves the complexities associated with binary instrumentation so that even software engineers without expertise in the field can use it. Deviare takes care of code injection, parameter marshalling, and inter-process communication. We created Deviare API in 2007 and continually improve it. Intercepting applications is a complex task. We test multiple application environments to ensure that the end user has a trouble-free experience. Deviare also has a focus on performance handling thousands of hooks with little footprint.

Code instrumentation is used in several other areas like: tracing and debugging, sandboxing and browser security, malware analysis, video conference recording, and gaming.

Deviare runtime runs on any computer with Microsoft Windows XP or later OS installed.

To compile Deviare and/or build samples you need:

• Visual Studio 2012 with Update 4 or later.
• .NET Framework 4.
• Windows SDK 8 with all .NET Framework components installed.

NOTE: Some of the files you'll find in the BIN folder are NOT generated during compilation, such as the database (.db) files. Deviare needs these files to work. It you create new databases, don't forget to move them to the BIN folder.
