Socket
Blocks malicious open source packages in real time and adds reachability-based CVE triage.
Socket Overview
What it does
Socket is a Software Supply Chain Security (SSCS) platform that proactively detects and blocks malicious open source packages before they reach a codebase, targeting the install-time and dependency-update attacks that conventional Software Composition Analysis (SCA) tools miss. Instead of matching packages against a database of known CVEs, Socket analyzes the actual behavior of each dependency, including install scripts, obfuscated code, network access, and use of privileged APIs, to catch zero-day supply chain attacks across the npm, PyPI, and Go ecosystems.
How it works
The platform embeds at several points in the development lifecycle: a GitHub app that flags risky dependency changes inside pull requests, a command-line Firewall that blocks malicious packages at install time, and a web dashboard with dependency search across millions of open source packages. Reachability analysis, added through the acquisition of Coana, narrows CVE noise to vulnerabilities that are actually reachable in the code, cutting a large share of false positives. Integrations with GitLab, Bitbucket, Azure DevOps, and Jenkins extend gating into CI/CD pipelines. Named customers include Anthropic, Vercel, Replit, and Figma.
Credentials and traction
Socket is SOC 2 Type II compliant. The platform protects more than 27,000 organizations and 1.5 million code repositories, with adoption concentrated among AI model developers and developer-tooling companies. It is built by the team behind widely used open source projects including WebTorrent and StandardJS, and serves technology, financial services, media, and healthcare organizations evaluating open source dependency risk at scale.
Key Capabilities
mapped to solution categoriesDeep analysis of binaries and packages to detect tampering, malware, and hidden threats beyond manifest-based scanning.
Risk context for open-source dependencies including reachability, exploitability, and upgrade impact.
Governs third-party software consumption to apply consistent software supply chain security policy.
Live visibility into code, components, pipelines, and developer activity across the software development lifecycle.
Compiles vendor, third-party and open-source maintainer reputation to flag risk from unmaintained, deprecated or abandoned software.
On-demand generation of software, firmware, and hardware bills of materials (SBOM, FBOM, HBOM) for endpoints, servers, and network devices, extending component inventory below the application layer.
Assessment and policy enforcement of CI/CD pipeline configuration, access, and integrity.
Identifies packages with known-malicious behavior (typosquatting, dependency confusion, backdoored releases), distinct from packages with CVEs in legitimate code.
Determines whether a vulnerable function is actually reachable and called in the codebase: not merely present in the dependency tree. Reduces actionable CVEs to those with real exploit paths; requires static code analysis on top of dependency scanning.
Traverses the full dependency graph to surface CVEs in indirect dependencies, packages required by your direct dependencies. Direct-only scanning misses the majority of vulnerable code paths in modern polyglot projects.
Scores open source dependency health using release cadence, maintainer count, contributor reputation, and popularity, flagging abandoned packages beyond known CVEs.
Blocks or flags PRs in CI/CD pipelines based on policy-defined thresholds, configurable by severity, CVSS score, exploitability, fix availability, or CVE age. Prevents vulnerable code from merging without requiring zero-tolerance policies.
Defines open source policies (banned licenses, blocked packages, version floors, severity gates) as version-controlled rules applied automatically at scan time across repositories.
Identifies OSS licenses in the dependency tree and flags conflicts with the project's target license or policy (GPL contamination, copyleft obligations, export-controlled components). Separate from vulnerability detection.
Exports the dependency inventory as a machine-readable Software Bill of Materials in SPDX or CycloneDX format, consumable by downstream vulnerability scanners, compliance tools, and procurement workflows.
