Stacklok is a cybersecurity platform offering complete end-to-end visibility into an organization’s software supply chain, including open-source ecosystems. The company’s platform provides an organization’s developers with tools that surface provence data to enable transparency within a software supply chain ledger for both non-repudiation and cryptographic signatures.
