Posted by Laurent Simon and Azeem Shaikh, Google Open Source Security Team (GOSST) Since our July announcement of Scorecards V2, the Scorecards project—an automated security tool to flag risky supply chain practices in open source projects—has grown steadily to over 40 unique contributors and 18 implemented security checks. Today we are proud to announce the V4 release of Scorecards, with larger scaling, a new security check, and a new Scorecards GitHub Action for easier security automation.

The Scorecards Action is released in partnership with GitHub and is available from GitHub's Marketplace. The Action makes using Scorecards easier than ever: it runs automatically on repository changes to alert developers about risky supply-chain practices. Maintainers can view the alerts on GitHub's code scanning dashboard, which is available for free to public repositories on GitHub.com and via GitHub Advanced Security for private repositories.

Additionally, we have scaled our weekly Scorecards scans to over one million GitHub repositories, and have partnered with the Open Source Insights website for easy user access to the data.
