Zast AI Content is a static application security testing tool that analyzes Java and JavaScript/TypeScript applications for security vulnerabilities. The platform accepts JAR or WAR files for Java projects with a file size limit of 500 MB. Users can upload their application archives through a drag-and-drop interface or file selection dialog. The tool performs automated security analysis on the uploaded code to identify potential security issues. The platform currently supports Java and JavaScript/TypeScript languages, with additional language support planned for future releases. The service includes a demo guide feature to help users understand the analysis workflow and capabilities. The tool operates as a cloud-based service where users upload their compiled application files for security scanning. Analysis results are provided after the scanning process completes, allowing developers to identify and address security vulnerabilities in their applications before deployment.
