The 2024 Tidelift Maintainer Impact Report is a comprehensive document that discusses the critical role of open source software in modern applications, which often comprises a significant portion of the codebase. It outlines the increasing risks associated with open source usage, particularly in light of high-profile security vulnerabilities that have raised concerns at the board level. The report emphasizes the importance of maintaining secure open source code, especially as new regulations like the Cyber Resilience Act and Product Liability Directive impose responsibilities on organizations. It highlights the misconception that maintainers alone are responsible for the security of open source software, noting that many maintainers are unpaid volunteers. The report also presents a case study demonstrating the benefits of investing in open source maintainers, showing how one organization improved application security and saved substantial costs by ensuring their software supply chain was secure and well-maintained. This document serves as a guide for organizations looking to mitigate risks while leveraging open source resources effectively.
