Socket
Supply chain security that detects malicious packages before they compromise your app.
Security
Free tier
Overview
Socket proactively detects supply chain attacks by analyzing what open source packages actually do. Instead of checking for known CVEs, it looks for suspicious behavior: install scripts, network access, filesystem writes, and obfuscated code.
Strengths
- Detects supply chain attacks, not just known CVEs
- Behavioral analysis of package behavior
- GitHub integration with PR comments
- Supports npm, PyPI, and Go modules
Weaknesses
- Focused only on supply chain — not a full security suite
- Can flag legitimate packages with unusual behavior
- Newer product with evolving detection capabilities
- Language support still expanding
