Securing the world's code requires a collaborative effort among teams, companies, and individuals, leveraging community knowledge and partner technologies to enhance software security while enabling innovation. The widespread use of open-source software, which constitutes 99% of projects, brings inherited security risks, highlighted by a 71% increase in open-source-related breaches over five years. Organizations can enhance security by understanding their open-source inventory, automating fixes, and integrating security solutions into the developer workflow to reduce friction and improve productivity. By embedding security into the software development lifecycle and establishing organization-wide visibility and governance, businesses can manage application security without hindering operations. GitHub emphasizes that security is a shared responsibility and advocates for implementing solutions that secure the supply chain, custom code, and software lifecycle to foster a trustworthy digital future.
