A drop-in wrapper agent (pmg-style) that sits in front of npm, pip, and apt install commands, performing real-time behavioral and reputation analysis on each package before execution — checking version pinning, postinstall script contents, publish timestamp anomalies, and known malicious signatures. It integrates into CI/CD pipelines as a sidecar or pre-install hook, blocking or quarantining suspicious packages and alerting teams with a forensic report before any code runs.

March 2026 saw a cascade of high-profile supply chain compromises — axios, litellm, Trivy — that collectively exposed CI/CD secrets across thousands of organizations in a single month. Developer awareness is at a peak and security teams are actively budgeting for preventive tooling rather than post-incident remediation.
