About
Socket is a developer-first software supply chain security platform that proactively detects and blocks malicious open source packages in real time. Unlike reactive security tools, Socket analyzes the behavior of npm, PyPI, and other package dependencies to identify zero-day attacks, typosquatting, and supply chain compromises before they reach production. Trusted by enterprises across technology, healthcare, finance, and media, Socket detects over 100 zero-day attacks every week and integrates directly with GitHub workflows.
