Pathways to Enable Secure Open-Source Ecosystems (PESOSE)

The Pathways to Enable Secure Open-Source Ecosystems (PESOSE) program supports the translation of open-source science and engineering-focused research products into safe and sustainable ecosystems that address national and societal challenges. The program seeks to create managing organizations for these ecosystems, ensuring strong governance, distributed development, and broad user communities across academia, industry, and government. The program also supports enhancements to the safety, security, and privacy of Open-Source Ecosystems (OSE) by addressing significant vulnerabilities, both technical and socio-technical. Key aspects of this opportunity include: • The program supports three types of proposals: scoping and planning the establishment of an OSE, establishing and expanding a sustainable OSE, and improving the safety, security, and privacy of an existing OSE. • Eligible proposers include U.S.-based commercial organizations, non-profit organizations, institutions of higher education, and other federal agencies and federally funded research and development centers. • Proposals must be submitted by the deadline of September 1, 2026. • The program expects to make approximately 60 awards, with a total estimated funding of $40,000,000.
