Our Take

Socket is solving supply chain security the smart way — instead of playing catch-up with CVE databases like everyone else, they're watching what code actually does at runtime: network calls, shell spawning, hidden scripts, env var reads. That's the move. If you're shipping npm packages without knowing what they're really doing to your infra, this is the reality check you need.

Socket is a developer-first security platform that proactively detects and blocks malicious packages in real time by analyzing the behavior of dependencies across all major registries (npm, pip, RubyGems, etc.), preventing zero-day supply chain attacks before they reach code.

Key Features

Socket for GitHub (PR review integration), Socket Firewall (CLI blocking at install), Socket CLI, Socket Certified Patches, Socket Web Extension, Socket Optimize, Socket Dependency Search, Socket Reachability, Real-time threat detection, Package Alerts

Problem It Solves

Software supply chain attacks from malicious packages, typosquatting, dependency confusion, and other threats in open source ecosystems. Traditional security tools are reactive and disrupt developer workflows.

Target Customer

Engineering teams, security teams, developers building applications with open source dependencies

Use Cases

Blocking malicious packages at install time, Detecting risky dependency additions in PRs, Filtering vulnerability noise for reachable code, Scanning packages across registries, Securing AI-driven development
