Historical record. This platform is discontinued and should not be treated as an active option.

FOSSA, the Free and Open Source Software Audit project, was created by the European Union to improve the security of widely used open source infrastructure through audits, hackathons, and bug-bounty programmes. The programme has ended, but it remains an important historical example of government-backed grant and bounty funding for open source security.
