COcyber Hackathon — civil-defence cyber challenges

An online pan-European hackathon bringing civilian and defence cybersecurity communities together around shared challenges, with winning teams pitched at the COcyber final conference.

Hackathons are usually civilian or defence, rarely both. Running them in the same room — virtually — produced two outcomes that mattered: it surfaced real, operational problems where the two sides clearly benefit from talking, and it gave young teams a way into the dual-use space that does not require an existing security clearance or industry contract. The event itself is one-off; the team list, the challenges and the open-source artefacts are the lasting outputs.
