A drop-in npm proxy and package manager wrapper that intercepts every install, validates packages in real time against a threat intelligence feed, and sandboxes install scripts before execution. It combines manifest diffing, behavioral analysis (network calls, file access patterns), and cryptographic provenance checks against known-good release pipelines — blocking or alerting before any malicious payload executes. A lightweight CI/CD integration adds the same protection to GitHub Actions, GitLab CI, and other runners with a single line of config.

March 2026 alone saw major compromises across axios, Bitwarden CLI, litellm, and Trivy, affecting hundreds of millions of weekly downloads and reaching critical infrastructure at companies like OpenAI. The frequency and sophistication of npm supply chain attacks has sharply accelerated, creating urgent demand for tooling that goes beyond advisory notifications and actually stops attacks at install time.
