Socket detects supply chain attacks in open-source dependencies by analyzing package behavior, not known CVEs.
Socket takes a different approach to software supply chain security: instead of waiting for CVEs, it watches what packages actually do. Its analysis flags install scripts, network access, shell commands, and other risky behaviors that signal malicious or compromised packages, catching zero-day supply chain attacks as they ship. It integrates with GitHub, VS Code, and npm workflows, blocking bad dependencies before they reach production.
Socket’s GitHub integration makes risk visible where dependency decisions happen: pull requests that add packages come with behavior reports, so reviewers see install scripts and network calls before merging. This shift-left approach catches typosquats and malicious updates in hours, not months.
The detection model watches for behavior signals — network calls during install, obfuscated scripts, unusual permissions — which is how zero-day supply chain attacks betray themselves. Security teams value that the tool acts at the moment dependency decisions are made.
Socket offers a free tier for open-source and small teams. Paid plans add private repo coverage, policy enforcement, and enterprise support.
Engineering teams that consume open-source packages and want protection from malicious or compromised dependencies.
Yes, free coverage exists for public projects and small teams; larger orgs need paid plans.
Yes, Socket provides APIs and CI integrations for automating dependency risk decisions.
Snyk and Dependabot track known vulnerabilities; Socket catches malicious behavior before a CVE exists.
npm and PyPI are core, with coverage of other open-source registries expanding.
Yes, policy controls can prevent flagged packages from entering your dependency tree.
Checks are designed to be lightweight and non-blocking to development velocity.
Yes, free coverage for public projects helps maintainers protect their ecosystems.
Yes, enterprise plans add policy enforcement and private repository coverage.
npm and PyPI lead, with additional open-source registries supported.
Malicious packages betray themselves through risky behavior long before any vulnerability database entry exists.
