Addressing the Increasing Threat of Supply Chain Attacks
With more than 90% of modern applications relying on open source, the risk of supply chain attacks has grown significantly, surpassing the capabilities of traditional Software Composition Analysis (SCA) tools. Socket’s innovative platform takes a proactive approach by continuously monitoring open source packages for malicious behaviors such as backdoors, typo-squatting, and obfuscated code. This comprehensive strategy not only detects vulnerabilities but also blocks threats in real time, setting a new standard for software supply chain security.
Feross Aboukhadijeh, Founder and CEO of Socket, highlighted the platform’s rapid progress over the past year: “Our technology has enabled leading AI, B2B, and finance companies to move away from legacy SCA tools like Snyk. We are not just identifying vulnerabilities; we are actively detecting and preventing malicious threats.”
Advancing Software Security with Next-Generation Features
Socket’s platform now supports six programming languages, including Java and Ruby, making it a versatile alternative to outdated SCA tools. The platform also addresses key use cases such as license compliance and reachability analysis, providing a more comprehensive approach to application security.
Jason Clinton, CISO at Anthropic, praised Socket’s capabilities: “Attackers are evolving their supply chain tactics, and traditional tools are struggling to keep up. Socket’s real-time threat detection significantly strengthens our defense against zero-day supply chain attacks.”
Amjad Masad, Founder and CEO of Replit, added, “As generative AI accelerates software development, the risk of malicious or vulnerable packages slipping through increases. Socket’s preventative security measures catch threats before they compromise our systems, allowing developers to innovate without compromising on security.”
Accelerating Growth Through Innovation
Over the past year, Socket has introduced groundbreaking features, including AI-powered threat detection across six programming language ecosystems, allowing the platform to detect and block over 100 supply chain attacks weekly. This rapid pace of innovation has fueled Socket’s growth, with the platform now protecting more than 7,500 organizations and 300,000 GitHub repositories.
“Socket is revolutionizing software security,” said Ramtin Naimi, Founder and Managing Partner at Abstract Ventures. “Its proactive approach to preventing software supply chain threats is precisely what the industry needs. Socket’s ability to replace legacy SCA tools has already made it the go-to solution for companies seeking to enhance their application security.”
Building a World-Class Team to Tackle Urgent Security Challenges
With the new funding, Socket plans to scale its product development and expand its team, actively hiring for roles in engineering, product, and sales. The company aims to tackle one of the most urgent challenges in software security: preventing supply chain attacks before they infiltrate an organization.
Elad Gil, investor and co-founder at Color Health, commented on Socket’s impact: “It’s rare to see a team deliver such meaningful results at this pace. Socket is addressing one of the hardest problems in security, in an industry segment that has seen little innovation.”
As the frequency and complexity of supply chain attacks continue to grow, organizations must move beyond reactive security measures. Socket’s proactive approach to stopping threats at the source is paving the way for a safer open source ecosystem, giving developers and security teams the confidence to focus on building great products.
