Modern apps rely heavily on dependencies, with attacks often targeting open source packages
Open source packages make up the majority of modern application code.
Modern apps rely on thousands of open source packages, making dependencies a critical supply chain risk and a common hiding place for malicious code.
Developers review almost none of it before it ships.
Packages enter through managers, updates, AI code, and transitive installs, often reaching production before teams can review every change.
CVE databases don't flag malicious packages — only known vulnerabilities.
CVE databases track disclosed vulnerabilities, not malicious package behavior like secret theft, exfiltration, install scripts, or impersonation.
Vulnerability scanners were built for a different threat
They check packages against a list of known bad versions. Malicious packages don't appear on that list – they're new, they look legitimate, and they execute on install.
Socket’s AI scans major registries and blocks attacks within minutes
Socket analyzes package code and behavior, flagging network calls, file access, shell execution, and obfuscation.
GitHub App: PR-level alerts on new dependencies
This proactive approach helps you intercept package downloads and block known malware before it can infiltrate your environment.
CLI: protection from the terminal
Ensure your terminal is secure by clearly defining what actions are permitted, what triggers warnings, and what gets blocked, all in line with your organization's security and licensing guidelines.
Firewall: block malicious packages org-wide before they reach any developer
Implement a robust firewall that prevents harmful packages from infiltrating the organization, ensuring that no developer is exposed to potential threats.
Socket integrates where developers already work
Socket checks every pull request, flags risky dependencies before they merge, and gives developers the context to make a fast decision — without slowing down the team.
We're open source maintainers who saw the supply chain problem from the inside
Socket was created by people who were already deep in the open source ecosystem: maintaining packages, working with dependency chains, and seeing how quickly trust could be abused. Before supply chain attacks became front page news, the pattern was already visible to maintainers. The tools built for known vulnerabilities were not designed to catch malicious package behavior in real time. That perspective shaped Socket from the beginning: protect the ecosystem, help developers move quickly, and make security work with the way builders already build.
Socket is trusted and loved by the Security Community
Leaders at organizations across all industries trust Socket to safeguard their software supply chains, ensuring their products remain secure while driving business success.
