The Chainguard team has developed SLSA – the most recognized framework for supply chain security and Sigstore – an open source project for signing software artifacts which ensures proper software provenance. Building on the open source momentum, the company is developing enterprise solutions to mitigate attacks along every stage of the software development cycle without sacrificing developer productivity.
