Socket undergoes annual SOC2 Type II audits. Socket customers can request a copy of the full SOC2 Type II report.

Work with a dedicated Customer Success Manager to help you get the most out of Socket.

Restrict logins to the organization to SSO, preventing other login methods (e.g. GitHub or email)

Have members who are not admins in the organization. Restrict access with Role-based Access Control (RBAC).

Integrates with top AI coding assistants — including Claude Code, Claude Desktop, Gemini Code, and other MCP-compatible agents — to provide real-time dependency insights, vulnerability context, and security scoring directly inside your AI-powered coding environment.

Get a clear view of your current supply chain health. Track active alerts, dependency risk, and security trends across your org—all in one place on the Socket Dashboard and via API.

Allows organization owners and admins to access detailed records of actions taken by members of their organization, complete with timestamps.

Automatically generate fixes for vulnerable dependencies with safe, tested upgrades.

Prevent compromised packages from infiltrating your supply chain by monitoring for changes in real-time. Block 70+ types of open source threats, including malware, typo-squatting, and backdoors.

Shift left by catching risky or low-quality dependencies before they're merged. Use CI gating, PR comments, and visual warnings to guide developers early and enforce security guardrails.

Removes known vulnerabilities instantly without upgrading dependencies. Delivers safe, human-reviewed, AI-validated patches that live in your repo, eliminate risky updates, and keep builds stable while reducing supply chain exposure.

Socket opens pull requests for each patch so developers can review and merge fixes with no extra work.

Receive updated patches as new CVEs and package releases appear, with no extra work.

Patches for the most severe CVEs are free on every plan, and the Socket CLI applies them with no account or signup required. Try the patch quality on the riskiest issues first; if it's good enough for active threats, it's good enough for the rest.

When a dependency has multiple CVEs, Socket diff-merges every applicable patch into a single combined fix. Free users apply patches one CVE at a time; paid plans collapse them into one dependency change, so you remediate the whole package in a single step.

Patches for medium- and lower-severity CVEs, beyond the critical-tier coverage included with every plan. Covers the long tail of vulnerabilities other scanners flag but never actually fix.

Apply any certified patch to your repo with a single click from the Socket dashboard or CLI. No version bumps, no manual diffs, no upgrade roulette.

Focus on vulnerabilities your code can actually hit, then fix them instantly with patches.

Use patches vetted by experienced maintainers so you can remediate confidently. Patches ship with automated behavioral tests to ensure nothing breaks.
