Dependency Firewall: Block risky packages before the build

Attackers disguise malicious packages as ones you trust. In June 2026, GitLab researchers found five malicious PyPI packages , four of them typosquats of Flask, Requests, and NumPy, that run at install time and steal CI/CD credentials. Additionally, AI coding agents now add open source dependencies on their own, often unreviewed, so developers don’t have oversight into what packages may contaminate your build.
