Compliance with government cybersecurity requirements

The best way for organizations selling software to the U.S. government to comply with mandatory secure software development requirements, by providing the data they need to attest to the secure development practices of the open source components used in their applications.


The only source for human-validated data on secure software development practices for open source

Tidelift pays open source maintainers to ensure their projects follow industry-standard secure software development practices (like those found in the NIST Secure Software Development Framework and the OpenSSF Scorecards). We work together with our maintainer partners to provide this unique and valuable data, so you know if, when, and how your open source will be secured and maintained.
