GUAC vs Wisec

GUAC ingests software metadata, including software bills of materials, and connects it into a queryable view of supply-chain relationships. That portfolio-level view lets developers, operations and security practitioners, and Open Source Program Offices examine dependencies across software rather than one SBOM at a time. Teams can look for vulnerable, deprecated, unsupported, or duplicated dependencies and identify risky upstreams using OpenSSF Scorecard. APIs and a visualization tool support queries and exploration. GUAC documents SPDX and CycloneDX SBOM formats, with graph enrichment from OSV for vulnerability data, ClearlyDefined for license information, and Deps.dev for dependency information. Its GraphQL server can use in-memory storage or PostgreSQL for persistence. Collectors can read or watch files, storage buckets, and Git repositories; the filesystem collector is stable, while other collectors are experimental. Setup uses Docker Compose and requires Docker, Docker Compose, and jq. The project is an OpenSSF Incubating Project. GUAC is free and open source: its code is under the MIT license, and documentation content is under CC BY 4.0.

Wisec collects, signs, and preserves software build evidence for teams preparing for Cyber Resilience Act readiness. It links builds in a signed chain using Ed25519, SLSA provenance, and public Sigstore/Rekor timestamping. It generates signed CycloneDX SBOMs and VEX documents describing the exploitability status of detected CVEs. Eleven anomaly rules run on each build, covering project history and known-bad patterns. Teams can set CI gate policies to block or warn on secrets, vulnerable dependencies, unapproved contributors, risk thresholds, and CVE severity. Wisec supports GitLab CI, GitHub Actions, Jenkins, and Azure DevOps, and imports SARIF v2.1.0 findings from tools such as CodeQL, Semgrep, Snyk, and Trivy. It maps evidence to NIS2, SOC2, ISO 27001, and CRA and exports PDF reports; CRA and ISO 27001 mapping is not a conformity claim. The maker says data is encrypted in transit and at rest, hosted in France, and kept within the EU. Plans include Free at free, Business at €990 a year, and Pro at €2,990 a year.
