Mozilla Foundation
The Secure Open Source (SOS) track of Mozilla Open Source Support paid for third-party security audits of widely used open-source software and the remedial work to fix problems found. Of the awards with a disclosed dollar amount, sizes ranged from $15,000 to $187,500; many entries in Mozilla's award directory do not disclose an amount. Mozilla selected candidates directly rather than running an open application process. The broader MOSS program is on indefinite hiatus and not accepting new applications following Mozilla's 2020 restructuring.
