Socket, a company protecting software from supply chain attacks, announced a $40 million funding round. The company monitors open-source packages for malicious behaviors like backdoors, typo-squatting, and obfuscated code.
The Socket Series B $40 million funding round was led by Abstract Ventures, with participation from Elad Gil, Andreessen Horowitz (a16z), and a stellar group of angel investors, including Bret Taylor (OpenAI), Phil Venables (Google), Scott Johnston (Docker), Christina Cacioppo (Vanta), Ann Mather (Pixar, Alphabet, Netflix, Airbnb), and Tobias Lütke (Shopify), among others. This latest round brings Socket’s total funding to $65M, fueling its mission to modernize security for open-source software and build out its team across engineering, product, and design.
With 90% of modern applications built on open source, security has become more critical than ever. And Traditional Software Composition Analysis (SCA) tools have struggled to keep up with the rising tide of supply chain attacks.
Socket’s platform now supports six programming languages, including newly added Java and Ruby, and handles critical use cases like license enforcement and reachability analysis, making it a comprehensive replacement for legacy tools.
Over the past year, Socket has shipped groundbreaking features, including AI-powered threat detection for software dependencies in six programming language ecosystems, which has enabled it to detect and block over 100 software supply chain attacks every week. This pace of innovation has been key to Socket’s rapid growth, with the company now protecting over 7,500 organizations and 300,000 GitHub repositories.
Socket plans to accelerate product development and expand its team. The company is actively hiring for roles in engineering, product, and sales as it scales to meet the growing demand for its next-gen application security platform.
KEY QUOTES:
“We’ve seen incredible momentum over the past year. Our technology has made it possible for leading AI, B2B, and finance companies to switch from legacy SCA solutions like Snyk to Socket. We’re not just catching vulnerabilities — we’re detecting and blocking malicious threats in real-time.”
