The YAG Suite is a French-made innovative tool that takes SAST to the next level. YAGAAN is a combination of static analysis and machine-learning. It offers customers more than a sourcecode scanner. It also offers a smart suite to support application security audits and security and privacy through DevSecOps design processes. The YAG-Suite supports developers in understanding the vulnerability causes and consequences. It goes beyond traditional vulnerability detection. Its contextual remediation helps them to quickly fix the problem and improve their secure coding skills. YAG-Suite's unique 'code mining' allows for security investigations of unknown applications. It maps all relevant security mechanisms and provides querying capabilities to search out 0-days and other non-automatically detectable risks. PHP, Java and Python are currently supported. Next languages in roadmap are JS, C and C++.

Modern software development must be as fast as the business. The modern AppSec toolbox lacks integration, which creates complexity that slows down software development life cycles. Contrast reduces the complexity that hinders today's development teams. Legacy AppSec uses a single-size-fits all approach to vulnerability detection and remediation that is inefficient, costly, and expensive. Contrast automatically applies the most efficient analysis and remediation technique, greatly improving efficiency and effectiveness. Separate AppSec tools can create silos that hinder the collection of actionable intelligence across an application attack surface. Contrast provides centralized observability, which is crucial for managing risks and capitalizing upon operational efficiencies. This is both for security and development teams. Contrast Scan is a pipeline native product that delivers the speed, accuracy and integration required for modern software development.

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.
