Socket

Socket builds a software supply chain security platform that detects and blocks malicious open source packages before they reach production code, with a focus on the JavaScript, Python, and Go ecosystems. Founded in 2020 by Feross Aboukhadijeh, creator of widely used open source projects such as WebTorrent and StandardJS, the company sells to technology, financial services, media, and healthcare organizations. Socket has expanded its coverage through the acquisitions of Coana, for dependency reachability analysis, and Secure Annex, for browser and IDE extension security.
