https://cochran-vind-3.federatedjournals.com/why-qwiet-ais-prezero-surpasses-snyk-in-2025-1741820127 Static Application Security Testing (SAST) has become a crucial component in the DevSecOps approach, allowing companies to discover and eliminate security vulnerabilities early in the software development lifecycle. SAST can be integrated into continuous integration/continuous deployment (CI/CD) that allows developers to ensure that security is a key element of the development process. This article explores the importance of SAST to ensure the security of applications. It also examines its impact on the workflow of developers and how it can contribute to the success of DevSecOps. The Evolving Landscape of Application Security Security of applications is a significant issue in the digital age that is changing rapidly. This applies to organizations that are of any size and sectors. Due to the ever-growing complexity of software systems as well as the growing technological sophistication of cyber attacks traditional security methods are no longer sufficient. The need for a proactive, continuous and integrated approach to security of applications has given rise to the DevSecOps movement. DevSecOps is a paradigm shift in software development, in which security is seamlessly integrated into every phase of the development lifecycle. Through breaking down the barriers between security, development, and the operations team, DevSecOps enables organizations to create secure, high-quality software at a faster pace. Static Application Security Testing is at the heart of this new approach. Understanding Static Application Security Testing SAST is a white-box testing technique that analyses the source software of an application, but not running it. It scans the codebase to find security flaws that could be vulnerable like SQL injection and cross-site scripting (XSS) buffer overflows, and more. SAST tools use a variety of methods to spot security weaknesses in the early phases of de
