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.
