Function
Open Defensive Tooling
This category covers maintainable defensive software: frameworks, simulations, automation, monitoring utilities, and coordination tooling. Projects here should be practical and broadly usable by defenders, even when not every component is fully open source. It differs from education by delivering operational systems rather than curriculum, and from response by building capability before incidents happen.
