Description
The Pathways to Enable Secure Open-Source Ecosystems (PESOSE) program funds projects that aim to translate open-source science and engineering research products—such as software, hardware, machine learning models, languages, and data platforms—into robust, safe, and sustainable ecosystems. The program addresses national and societal challenges by supporting the creation and governance of open-source ecosystems (OSEs), enhancing their safety, security, and privacy, and ensuring their long-term sustainability and broad adoption. Projects can focus on scoping and planning new OSEs, establishing and expanding existing ones to meet emerging needs, or improving the security and privacy of critical open-source products.
