PMG launches as an open‑source firewall for software packages

PMG is introduced as an open‑source firewall for software package management. It intercepts package downloads and inspects them for known threats. The tool aims to prevent supply‑chain attacks on developers. PMG integrates with popular package managers to enforce security policies. The project is hosted on GitHub and invites community contributions. Early benchmarks show it can block malicious packages with minimal performance impact. Users can configure rules to allow or deny specific sources. The developers plan to expand support to additional ecosystems.
