Python and PyPI in Your Software Supply Chain

Python is everywhere — web, data science, automation, AI. PyPI is central to your dependencies, whether you use pip, twine, or hybrid stacks. But dependencies carry risks of outdated packages, license conflicts, and hidden vulnerabilities, including transitive ones. Sonatype acts as the enforcement and visibility layer, helping teams control what enters the build, monitor dependencies, and block malicious or noncompliant packages before production.

Supported Features

Proxying and Caching

Cache remote PyPI packages for faster, reliable access, reduce external dependencies.

Hosted Repositories

Host private/internal PyPI packages (e.g. internal libs, shared tools).

Repository Grouping

Expose unified views combining multiple PyPI repos (proxy + hosted).

Dependency Analysis

Parse requirements.txt, Pipfile.lock, pyproject.toml, identify full dependency graph.

Vulnerability Scanning

Detect known security vulnerabilities in direct and transitive PyPI packages.

License Governance

Enforce license policies (e.g. disallowed licenses, license conflicts) within your Python stack.

How Python Teams Derive Value

Modern Python development relies on many dependencies, often from uncontrolled sources. Adding visibility, governance, and automation to your PyPI workflows helps reduce risk without slowing innovation.

  • Proactive Supply Chain Security

    Find and fix vulnerabilities before production. Automated scans catch risks early, helping teams resolve issues quickly and with minimal disruption.

  • Reliable, Compliant Builds

    Ensure every build uses approved, verified packages. Caching and policy enforcement eliminate broken dependencies, block unauthorized code, and control licensing.

  • Complete Visibility Across Python Projects

    Get a clear view of Python dependencies across applications and teams. Reports and SBOM insights show where key packages are used, helping prioritize upgrades or maintenance.

Frequently Asked Questions

Can I use this with both public PyPI and private internal packages?

Yes. You can proxy remote PyPI, host internal packages, and group them into a unified repository view so that clients see it as a single source.

How do you detect vulnerabilities in Python dependencies?

We correlate package metadata, advisory databases (e.g. Python Packaging Advisory Database), and known CVEs. We scan both direct and transitive dependencies.

Does this require changes to developers’ tooling?

Minimal. Client tools such as pip or twine simply point to your managed PyPI endpoint. Developers continue to work with familiar workflows.
