## About

Based in Delaware, US, and founded in 2021 by its CEO Feross Aboukhadijeh, Socket, Inc. operates as a cybersecurity platform that protects companies from software supply chain attacks by leveraging applications from malware and security threats from open-source code. In May 2026, Socket, Inc. raised USD 60 million in series C funding led by Thrive Capital, with participation from Capital One Ventures, Andreessen Horowitz, and Abstract Ventures. The series C funding values Socket, Inc. at USD 1 billion post-money.

Socket, Inc. detects and blocks supply chain attacks before they strike by using static analysis to characterize the behavior of a package and determine what capabilities it uses. Socket also uses static analysis to detect usage of privileged APIs such as shell, filesystem, eval, and environment variables. The company alerts developers when packages change in security-relevant ways, highlighting events such as the introduction of install scripts, obfuscated code, or usage of privileged APIs such as shell, network, filesystem, and environment variables.

The company plans to utilize the May 2026 funding to expand the use of its open-source code security technology and integrated it into code-generation applications through partnerships.
