Big‑Dollar Security Startup Protects Open‑Source Code

Socket, a young cybersecurity firm, has just secured a new funding round that puts its worth at one billion dollars. The latest investment of sixty million dollars was led by Thrive Capital, with Andreessen Horowitz and Abstract Ventures staying on board, while Capital One Ventures joined as a fresh investor. The company was founded in 2020 and has grown fast because of the boom in artificial‑intelligence tools that help programmers write code. Companies such as Anthropic, OpenAI and Cursor use large models trained on public code repositories to speed up software development. This makes any weakness in that open‑source material a serious risk, and Socket’s solutions help guard against those threats.Anthropic and Cursor already use Socket’s technology, showing that the firm’s products are trusted by leaders in the AI coding space. By offering protection for code that is freely available online, Socket addresses a growing concern: nation‑state hackers targeting vulnerabilities in open‑source libraries. With the new capital, Socket plans to expand its services and reach more customers who rely on open‑source code. The valuation signals that investors see a strong future for companies that secure the foundations of modern software development.
