What is Free Static Application Security Testing (SAST) Software?

Static Application Security Testing (SAST) software analyzes the source code, binaries, or bytecode of an application to identify vulnerabilities before the code is run in production. This type of software scans the application at rest to detect issues such as coding errors, security flaws, and weaknesses like SQL injection, cross-site scripting (XSS), and buffer overflows. SAST tools provide developers with early insights into potential security vulnerabilities, allowing them to fix issues before deployment. These tools are typically integrated into the software development lifecycle (SDLC), supporting secure coding practices and helping teams build more secure applications.
