CST Verdict

Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:

DigiCert Software Trust Manager

Enterprise and mid-market teams managing complex software release pipelines need DigiCert Software Trust Manager for its hardware-backed key storage and multi-signer capability, which eliminates the operational bottleneck of single-person signing approval gates at scale. The platform's FIPS 140-2 and Common Criteria compliance, combined with NIST PQC algorithm support, satisfies both current regulatory requirements and forward-looking crypto agility in ways most competitors treat as roadmap items. Skip this if your organization lacks CI/CD maturity or views code signing as a compliance checkbox rather than a supply chain control point; the policy engine assumes teams actually want to enforce what gets signed.

Grafeas

DevSecOps teams managing complex supply chains across multiple build systems and registries should adopt Grafeas for its metadata standardization layer; it forces consistency where point tools create fragmentation, and the free, open-source model means no vendor lock-in on your attestation data. The API spec has 1,564 GitHub stars and backing from Google and IBM, indicating real production use rather than theoretical architecture. Skip this if you need out-of-the-box scanning or policy enforcement; Grafeas is a metadata foundation that requires you to wire it into your existing pipeline, not a replacement for SCA or SBOM tools.
