Checkmarx One Malicious Package Protection vs Ossprey: Side-by-Side Comparison (2026)

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.

Ossprey

Startup security teams building fast without governance infrastructure should start with Ossprey, since its free tier removes cost friction and GitHub Actions integration means zero friction deployment. The tool maps dependencies and generates SBOMs on day one, covering the GV.SC and ID.AM functions that early-stage companies skip entirely. Ossprey's real strength is catching malicious packages before they land in your build; its weakness is in post-incident response and remediation workflows, so you'll still need a separate process for handling findings at scale.
