Supply-chain Levels for Software Artifacts (SLSA) is a framework that strengthens software supply chain security by enforcing consistent builds, provenance tracking, and platform integrity. Scribe Security helps organizations achieve SLSA compliance by using its Valint tool to generate, sign, and verify provenance documents at each stage of the build process. With tailored support for SLSA Levels 1 through 3, Scribe enables secure, auditable, and trustworthy software builds through automated attestations, policy enforcement, and platform isolation practices.
