We're seeing increased use of Binary attestation for securing the software supply chain, particularly within regulated industries. The currently favored approaches seem to involve either building a custom system for implementing the binary verification or relying on a cloud vendor's service. We're encouraged to see the open-source in-toto enter this space. in-toto is a framework for cryptographically verifying every component and step along the path to production for a software artifact. The project includes a number of integrations into many widely used build, container auditing and deployment tools. A software supply chain tool can be a critical piece of an organization's security apparatus, so we like that as an open-source project, in-toto's behavior is transparent, and its own integrity and supply chain can be verified by the community. We'll have to wait and see if it'll gain a critical mass of users and contributors to compete in this space.
