CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Teams managing open-source dependencies at scale need sdc-check because it catches the supply-chain risks that traditional SCA tools skip: obfuscated payloads, malicious install scripts, and unsafe lock file mutations that signal post-fetch tampering. The 142 GitHub stars and zero-friction free model mean you can test it in your CI/CD pipeline today without procurement friction. Skip this if your org needs SBOM generation or license compliance scanning; sdc-check is narrowly focused on detecting active threats in dependency chains, not inventory management.
