The Secure Programming Group at the University of Virginia's Department of Computer Science is responsible for the development and ongoing maintenance of Splint. David Evans leads the project and serves as its main developer. Memory bounds checking was created by David Larochelle. Significant contributions to Splint's development were also made by University of Virginia students, including Chris Barker, David Friedman, Mike Lanouette, and Hien Phan. Splint serves as the evolution of LCLint, a tool that originated from a collaborative research effort between the Massachusetts Institute of Technology and Digital Equipment Corporation's System Research Center. David Evans was also the chief designer and developer of LCLint. The initial concept for a static checking tool aimed at identifying discrepancies between LCL specifications and their C implementations came from John Guttag and Jim Horning. Their insights into the design and functionality proved invaluable, playing a crucial role in shaping both LCLint and its successor, Splint. Together, the team has fostered a robust environment for developing tools that enhance software reliability and security.

True Code empowers development teams to efficiently produce secure code by automating the detection of vulnerabilities throughout the Software Development Life Cycle (SDLC) and the DevSecOps framework. By fostering seamless collaboration between security assessors and developers, True Code facilitates the early discovery of vulnerabilities, enabling quicker resolutions and promoting a proactive approach to security, often referred to as shifting left. Drawing on extensive experience in securing connected devices across various sectors, True Code aims to avert hacks that could undermine customer trust, lead to revenue declines, and result in expensive remedial actions post-launch. Historically, software evaluation has been a labor-intensive and costly endeavor, often plagued by lengthy timelines. Additionally, it is not unusual for assessments to occur at the tail end of the development process, leading to increased costs for fixing issues that could have been addressed during the earlier stages of development. Consequently, this approach not only elevates the overall efficiency of the development process but also significantly enhances product integrity and customer satisfaction.

CodeSonar uses a unified dataflow with symbolic execution analysis to examine the entire application's computations. CodeSonar's static analyze engine is extremely deep and does not rely on pattern matching or similar approximations. It finds 3-5 times more defects than other static analysis tools. SAST tools are able to be easily integrated into any team's software development process, unlike many other tools such as testing tools and compilers. SAST technologies such as CodeSonar attach to existing build environments to add analysis information. CodeSonar works in the same way as a compiler. However, CodeSonar creates an abstraction model of your entire program, instead of creating object codes. CodeSonar's symbolic execution engine analyzes the derived model and makes connections between them.
