At NetBird, our mission has always been to make secure private networking and remote access ridiculously simple for everyone — from home users to global enterprises. As an open source zero-trust network security platform powered by WireGuard®, we believe transparency and security must go hand in hand.

Earlier this year, we participated in GitHub’s Secure Open Source Fund (SOSS) , taking meaningful steps to strengthen not only our own platform, but also the broader open source ecosystem.

Raising the Bar for Open Source Security

The SOSS Fund supports impactful open source projects in identifying, addressing, and preventing vulnerabilities before they can affect millions of downstream users.

During the program, we accelerated improvements in areas that directly impact our users’ safety, including:

• Threat modeling to anticipate and neutralize potential attack vectors.
• Strengthening our supply chain security to ensure dependencies remain trustworthy.
• Automated vulnerability detection to catch issues earlier in the development process.
• Clearer security guidelines for contributors, making it easier for new participants to build securely.

Why This Matters for Networking

In today’s connected world, private networking software like NetBird forms part of the backbone of remote work, distributed infrastructure, and secure access for teams everywhere. A single vulnerability in such a project can ripple out through countless companies, devices, and services.

By applying the practices and knowledge gained through the SOSS Fund program, we have further hardened NetBird against potential threats — helping ensure that secure networking can be trusted by design, not just by implementation.

A Broader Effect

Security in open source is never isolated. Improvements to one project strengthen the entire dependency graph and protect countless other systems that rely on it.

Through enhanced build processes, stronger testing pipelines, and refined code review standards, the benefits of our SOSS Fund participation extend beyond NetBird’s direct users to any project that integrates or builds upon our work.

GitHub’s Secure Open Source Fund didn’t just help us ship code — it helped us ship trust. And that’s something our entire community can build on.
