Key features

Key features

SLSA-2 compliant builds

Packages are built with Cloud Build, including evidence of verifiable SLSA-compliance. We provide three levels of package assurance: level 1, built and signed by Google, level 2, securely built from vetted sources, and attested to all transitive dependencies, and level 3, including transitive closure of all dependencies and continuously scanned and fuzzed.

Enriched metadata in standard formats

SBOMs for each package come with enriched metadata including Cloud BuildArtifact Analysis, package health, and vulnerability impact data, provided in SPDX and VEX formats.

Fuzzing and vulnerability testing

Packages include OSV data and are regularly scanned, analyzed, and fuzz-tested for vulnerabilities.

Verifiable integrity and provenance plus secured distribution

Packages and metadata include end-to-end provenance of how the packages were built and tested.

Signed versions of the packages and their metadata are distributed from a Google-managed, secured, and protected Artifact Registry.

Ongoing portfolio expansion

New packages are added on an ongoing basis based on the open source projects that impact our customers.

Citi has been an advocate and active leader in the industry's efforts to secure enterprise software supply chains. Both Citi and Google see untrusted and unverified open source dependencies as a key risk vector. This is why we’ve been excited to be an early adopter of Google Cloud's new Assured OSS product. It can help reduce risk and protect OSS components commonly used by enterprises like us.
