Socket, a US-based provider of cybersecurity services, has secured $40m in a Series B funding round to address the emerging threats to software supply chain security.

Abstract Ventures spearheaded the investment round, which saw contributions from various investors and industry experts.

Elad Gil, Andreessen Horowitz (a16z), and angel investors including Bret Taylor (OpenAI), Phil Venables (Google), Scott Johnston (Docker) as well as Christina Cacioppo (Vanta), Ann Mather (Pixar, Alphabet, Netflix, Airbnb), and Tobias Lütke (Shopify) also participated in the funding round.

The recent funding increases Socket’s total capital to $65m.

The company focuses on modernising security for open source software. Its approach involves proactive monitoring of open source packages to identify and thwart malicious activities such as backdoors, typo-squatting, and obfuscated code.

The latest capital injection will be used by Socket to expedite its product development and expand its workforce.
