Checkmarx One Malicious Package Protection
Security teams managing open-source dependencies across development and production environments need Checkmarx One Malicious Package Protection because it catches poisoned packages before they execute, not after. The 410,000-package database with transitive dependency scanning and runtime detection covers both installation-time blocking and post-deployment correlation, addressing the full NIST GV.SC supply chain risk lifecycle. Skip this if your organization treats malicious packages as a low-priority threat or lacks the development toolchain integration bandwidth to enforce policies across multiple build systems.
Development teams with private npm or PyPI packages should use snync to block the one dependency confusion vector that most SCA tools ignore: unregistered private package names sitting unprotected on public registries. It's free and takes minutes to run against your package manifest, making it a no-friction addition to any CI/CD pipeline. Skip this if your organization doesn't publish internal packages or already enforces strict registry policies; the tool solves a specific attack surface, not general supply chain risk.
