Common Good Cyber is trying to create options for non-profit cybersecurity organizations, helping connect funding sources with matching organizations. Quad9 is in process with them to try to work on making connections, and I was pleased to do this interview. Finding funds for long-duration service-based organizations is a real challenge. Doing good by protecting people online is inexpensive, but isn't free. I'm interested in hearing your ideas of how to bridge the gap as we grow.

Congratulations to our friends at i3D.net !

Quad9's participation in Nonprofit Cyber is a natural match for our cybersecurity mission.
