Socket.dev

Supply chain security for npm and Python packages

Socket.dev detects and prevents supply chain attacks in open-source dependencies before they compromise your applications. Unlike traditional SCA tools that match known CVEs, Socket analyzes package behavior — detecting install scripts, network access, filesystem operations, and obfuscated code that indicate malicious intent. Monitors npm, Python (PyPI), and Go packages in real-time. Provides GitHub PR comments with risk assessments for new dependencies added to your projects.

About Socket.dev

Socket.dev takes a behavior-analysis approach to supply chain security rather than just matching known CVEs. It detects malicious packages by analyzing what code actually does — install scripts, network calls, filesystem access, obfuscated code.

Monitors npm, PyPI, and Go package ecosystems in real-time for newly published malicious packages, typosquatting attempts, and compromised maintainer accounts.

GitHub PR integration automatically comments on pull requests when new dependencies are added, showing risk scores, behavior analysis, and potential concerns. Teams can set policies to block risky packages.

Complements traditional SCA tools (Snyk, Semgrep) by catching zero-day supply chain attacks that have no CVE yet. Free for open-source projects.
