Noma Security
Definition
Noma Security is an Israeli company founded in 2023 that secures the supply chain of AI systems themselves: models, training data and development pipelines.
The new attack surface: not the network, but the AI itself
Traditional cybersecurity tools were built to protect networks, servers and applications. But AI systems open up an entirely different kind of risk: models that can be poisoned (data poisoning), AI agents that can be exploited through prompt injection, and a whole supply chain of libraries and ready-made models whose origin is not always certain. Noma Security, founded in 2023, came out of stealth in October 2024, with $32 million in funding. It built a platform for fully mapping and monitoring all the AI components running in an organization, including tools that popped up without official IT approval (shadow AI).
The company focuses on the gap between how fast organizations adopt AI tools and how slowly existing security tools adapt to these new threats.
Four layers of protection, end to end
The platform is made up of AI-SPM, which maps all the AI components in the organization and their risks; Agent Access Control, which determines which agents are allowed to act and which data they may access; AI-DR, which monitors injection attempts and data leaks in real time; and AI Red Teaming, which continuously tests the systems' resilience against simulated attacks. Noma Security also joined the Open Secure AI Alliance, an Nvidia initiative, and holds HIPAA, SOC 2 and ISO 27001 certifications.
According to the company's announcement, a single one of its customers processes hundreds of millions of AI requests every month, while scanning thousands of models and AI environments, including cloud, code repositories and agent development platforms.
Fast growth and a $100 million round
According to an official Noma Security announcement from July 2025, the company raised $100 million in a Series B led by Evolution Equity Partners, with continued participation from Ballistic Ventures and Glilot Capital, after the $32 million it had raised in seed and Series A rounds, announced on 31 October 2024. According to the company, its ARR grew by more than 1,300% in the year before the round, which, it claims, made it the fastest-growing company in the AI security category.
"AI agent adoption is exploding within our customer base and CISOs understand that AI innovation must be thoughtfully deployed with full guardrails," said Niv Braun, CEO and co-founder of Noma Security, in the funding announcement.
