Developer-focused platform securing software supply chains
Overview
Socket provides a developer-first security platform that protects software supply chains by securing open-source dependencies. It proactively detects and blocks malware and vulnerable packages in real time, integrating with developer workflows like GitHub so issues are surfaced as developers work. The product supports languages such as JavaScript, Python, and Go and offers a CLI and a browser extension to embed protection into existing toolchains. Unlike some security tools that scan after code is written or after deployment, Socket aims to stop threats before they are added to a codebase by embedding checks directly into developers’ workflows. The company's goal is to help organizations safely use open-source software by reducing the risk from compromised or outdated dependencies across the software development lifecycle.

↑ 2%Socket has announced support for the PHP ecosystem, integrating Composer and Packagist into its software supply chain security platform. PHP developers can now search packages, generate Software Bills of Materials from Composer projects, and detect supply chain risks across dependencies. PHP powers roughly 75% of websites with a known server-side language. Packagist hosts over 440,000 packages with more than 169 billion installations since 2012, and Composer downloads exceed 2 billion packages monthly. Socket's AI-powered platform detects zero-day threats, typosquatting, backdoors and obfuscated code beyond traditional vulnerability scanning. Package search and browsing are available immediately, whilst SBOM generation and security scanning are in experimental release. Socket protects 14,000 organisations and 1.2 million repositories, securing over 2 million commits monthly and identifying 1,000 supply chain attacks weekly.
