Semgrep has launched General Availability support for C and C++ languages, marking a significant advancement in static analysis tools by providing rapid, accurate scanning of these complex languages directly from the source code. Unlike traditional methods that require time-consuming compilations and are hindered by the complexities of preprocessor directives, Semgrep utilizes the tree-sitter parsing library to handle ambiguities and parse both C/C++ code and preprocessor directives efficiently without needing a build step. This approach significantly accelerates the scanning process and integrates seamlessly into developer workflows, allowing for quick identification and prioritization of vulnerabilities. By leveraging tree-sitter's error recovery capabilities and focusing on practical programming patterns, Semgrep offers comprehensive coverage that rivals traditional Static Application Security Testing (SAST) tools while maintaining superior speed and accuracy. The development team has overcome significant challenges to deliver a modern analysis tool that supports C/C++ projects, helping developers reduce their dependency on legacy systems and improve application security.

Scaling an effective application security (AppSec) program is challenging, requiring tools that integrate seamlessly into the developer workflow without adding friction. Customizability in Static Application Security Testing (SAST) tools, as highlighted by Semgrep, is crucial for gaining developer buy-in and enhancing security processes. Modern SAST tools often overwhelm developers with findings, including false positives, which erodes trust. Semgrep emphasizes the need for customizable policies and rules, allowing AppSec engineers to manage the visibility and behavior of findings according to their accuracy and relevance. This customization facilitates a more efficient workflow, enabling developers to focus on actionable issues and improving fix rates. By customizing rules to match specific project needs, organizations can reduce noise and improve the accuracy of their SAST tools. The approach fosters trust in security processes by ensuring developers understand findings and how to address them, ultimately supporting the shift-left movement in AppSec.
