Israeli cybersecurity firm Noma Security has secured $100 million in Series B funding to accelerate the growth of its AI and AI agent security platform. The round was led by Evolution Equity Partners, with participation from Ballistic Ventures and Glilot Capital.

Founded in 2023 and emerging from stealth in 2024 with $32 million in Series A backing, Noma has quickly positioned itself as a key player in securing enterprise AI adoption. The company’s platform offers a comprehensive suite of capabilities, including AI security posture management, application protection, governance, compliance, and specialized defenses for AI agents.

The platform continuously maps all AI assets—spanning data platforms, cloud infrastructure, and AI agents—while actively monitoring for misconfigurations, supply chain vulnerabilities, model-level risks, and regulatory gaps. Its runtime protection layer enforces guardrails on AI models and agents, blocking threats such as malicious prompts, rogue outputs, and unauthorized activity.

CEO and co-founder Niv Braun highlighted the rapid growth of AI agent adoption across enterprise environments. “CISOs understand that AI innovation must be secured from the ground up. Noma is the only cybersecurity provider delivering an end-to-end platform tailored to the unique risks of agentic AI,” Braun said.

With this latest funding, Noma plans to expand its product capabilities, grow its customer base, and reinforce its mission to provide proactive, scalable security for organizations embracing AI at scale.

As AI becomes deeply embedded in enterprise infrastructure, Noma’s platform aims to ensure that innovation proceeds with robust protection—making it a timely solution for businesses navigating the complex landscape of AI risk.
