Noma Security is an enterprise platform that secures the full agentic AI lifecycle — covering the data and model supply chain, runtime LLM and agent activity, and AI governance. It is built to protect organizations against threats such as prompt injection, agent hijacking, sensitive data leakage, and model supply-chain risk as companies adopt AI agents in production.

The platform works across the AI development and runtime stack: it inspects data pipelines and model provenance, monitors live LLM and agent behavior for anomalous or malicious activity, and enforces governance policies so security and compliance teams retain visibility and control. This end-to-end coverage targets the gap between traditional application security tools and the new attack surface introduced by autonomous AI agents.

Noma Security was founded in 2023 by CEO Niv Braun and CTO Alon Tron, who met in the Israeli military's 8200 intelligence unit. The company is headquartered in Israel and emerged from stealth in November 2024 with customers already in production across financial services, life sciences, retail, and big tech.

Noma's growth has been steep, with the company reporting ARR growth of more than 1,300% in the year to mid-2025. In July 2025 it closed a $100 million Series B led by Evolution Equity Partners, with continued participation from Ballistic Ventures and Glilot Capital, bringing total funding to roughly $132 million. The capital is being used to roughly triple R&D and scale global sales and customer success.

Noma's differentiation is full-lifecycle coverage purpose-built for agentic AI rather than a single point control. As enterprises deploy autonomous agents with access to tools and data, Noma competes in the emerging AI security category by combining supply-chain integrity, runtime defense, and governance in one platform.
