Socket — Technical Overview
Socket is a freemium, open-source software supply chain security platform founded in 2022 (HQ: United States) that provides real-time detection and blocking of malicious open source packages across 10+ languages and major registries.
Core Capabilities
- Zero-day supply chain attack blocking — proactive threat detection without relying solely on CVE databases
- Real-time malicious package detection across major registries, catching typosquatting, protestware, and dependency confusion attacks
- Reachability analysis that eliminates 90%+ of CVE noise by determining whether vulnerable code paths are actually reachable in your codebase
- Socket Firewall — blocks malicious packages at install time before they can execute
- GitHub PR integration — flags risky dependency changes inline during code review, before merge
Architecture & Integration
Socket exposes an API and supports self-hosting. It integrates natively with:
GitHub · GitLab · Bitbucket · Azure DevOps · Slack · Vanta · SIEM · MCP server · IDE plugins
