A lightweight agent that wraps package manager commands (npm, pip, cargo, etc.) and performs pre-install verification: manifest diffing against known-good baselines, sandboxed install-time network behavior analysis, and streaming comparison against a continuously updated threat intelligence feed. Suspicious packages are blocked before postinstall scripts fire, with instant Slack/PagerDuty alerts and an audit trail per install event. A SaaS^? backend aggregates threat signals across all customers to detect zero-day compromised packages faster than any single team could.

The March–April 2026 wave of attacks (axios, litellm, Trivy, Chalk/Debug, GlueStack) hit packages with 50M–300M weekly downloads and compromised North Korean APT-linked infrastructure, pushing supply chain security from niche concern to board-level risk. Developer awareness is at an all-time high, creating immediate demand for turnkey protective tooling rather than manual remediation guides.
