Opportunity: GitHub Secure Open Source Fund
Published on August 13, 2025 by Grace

We’re excited to share that GitHub’s Secure Open Source (SOS) Fund is accepting applications for its next cohort starting in September. The fund supports critical open source projects with resources for security audits, testing, tooling, and other improvements. 

The goal of the SOS Fund is to help improve security across widely-used open source projects by funding security audits, testing, tooling, and other improvements. GitHub is looking to support projects that are:
  • Actively maintained and widely used
  • Critical to the broader software supply chain
  • In a position to meaningfully improve their security posture with funding and support

In the last Secure Open Source  Fund round, several of our hosted projects took part. Mautic was one such project and they shared their experience, which you can read about here: https://mautic.org/blog/mautic-graduates-from-the-github-secure-open-source-program/

As a fiscal host, Open Source Collective has the opportunity to refer hosted projects for participation in the next cohort of their program which starts in September. If you’re interested in being considered for a referral nomination, please reach out to us at [email protected] asap.  If selected, GitHub will reach out to you directly to explore next steps.
