About a year ago, Google announced its Assured Open Source Software (Assured OSS) service, a service that helps developers defend against supply chain security attacks by regularly scanning and analyzing some of the world’s most popular software libraries for vulnerabilities. Today, Google is launching Assured OSS into general availability with support for well over a thousand Java and Python packages — and while Google didn’t initially disclose pricing when it first announced the service, the company has now revealed that it will be available for free.
