The most valuable is the developer experience and the extensibility of the overall ecosystem.
GitHub Advanced Security ensures that user passwords or sensitive information remain protected in code, using AI-powered CodeQL for trusted results. With valuable features like security scans and dependency management, it offers initial setup simplicity. However, it needs a centralized dashboard for project reports, expansion in language support, and a refined deployment process. Improvements in vulnerability updates and customized scan rules would enhance its developer-centric experience and ecosystem extensibility.
