OSR Open Systems Resources

OSR Open Systems Resources develops Windows system software and tools.

At OSR, we take pride in knowing our business and knowing it well. We know Windows systems internals better than anyone, and we're happy to tell you that. We don't know MFC, COM, SOAP, Ruby on Rails or almost any of that other programming that happens up in user-mode. And we're happy to tell you that, too. So whatever you receive from OSR - whether it be a product, toolkit, seminar or project deliverable - you'll know that it was developed by an engineering team that is tops in its field. At our core, OSR's engineering team is comprised of very senior developers who live and breathe to find new and interesting ways to exploit Windows. Many of our engineers have over 15 years of experience developing systems software. Some have more than 20. Almost all have been working on kernel mode software for Windows since the first Windows NT Beta releases (1993). We love to delve into complex driver and file system projects. Developing new tools that expand on Windows functionality is fun, too, and we offer these to other system software developers as a way to spread our knowledge and help with their projects. Engaging OSR consulting services is a great way to take advantage of our knowledge. And don't forget our world-class training organization. The same engineers who develop and consult also teach - ensuring that our seminar students receive the REAL story about writing kernel-mode software.
