Mark and Julien recently represented Bootstrap in the second round of the GitHub Secure Open Source Fund this past June. The program is designed to programmatically and financially improve the security and sustainability of open source projects, and we were honored to be a part of it.
GitHub brought together open source maintainers, security experts, and ecosystem partners for an intensive, hands-on learning experience. Throughout three weeks, we had a few days of mixed expert-led presentations, collaborative workshops, and dedicated office hours with security specialists. Between sessions, we had homework: concrete, project-specific actions to immediately strengthen our codebase, workflows, and processes.

Bootstrap is a popular frontend framework for building responsive and mobile-first web applications, offering a  set of CSS and JavaScript components. Developers can learn about responsive web design principles, frontend development best practices, and CSS frameworks to design and develop modern and responsive web interfaces that work seamlessly across different devices and screen sizes.

Bootstrap

Bootstrap maintainers participated in GitHub's Secure Open Source Fund program, a three-week intensive training focused on improving security and sustainability of open source projects. The program covered threat modeling, secure GitHub Actions, incident response planning, and vulnerability management through expert-led sessions and workshops. As a result, Bootstrap implemented immediate security improvements including SBOM analysis, private vulnerability reporting, and fuzzing experiments, while planning longer-term initiatives like incident response plans and threat modeling.
