## Summary

Fastest-growing AI security company; raised $100M Series B (Jul 2025); $132M total in under 2 years; 1,300% ARR growth; secures AI agents, models, and data pipelines for enterprise use.

## Company Overview

Noma Security was founded to address the emerging and largely unaddressed security surface created by enterprise AI adoption. As organizations deploy AI systems, ML pipelines, and autonomous agents into production, they introduce new attack vectors — data poisoning, model theft, prompt injection, and unmonitored agent behavior — that conventional security tools are not designed to detect or prevent. Noma was built from the ground up to secure AI development pipelines and deployed AI agents in enterprise environments, with a platform that spans the full AI lifecycle from development through production.\n\nNoma's platform provides visibility and protection across AI supply chains, covering model provenance, training data integrity, API security, and real-time monitoring of AI agent behavior. It integrates with enterprise development environments and cloud platforms to surface risks that would otherwise go undetected by security operations teams unfamiliar with AI-specific threat models. Noma serves enterprises across regulated industries including financial services, healthcare, and technology, where the consequences of AI system compromise carry significant compliance and reputational risk.\n\nNoma raised a $100 million Series B in July 2025, bringing total funding to $132 million raised in under two years — an unusually fast fundraising trajectory that reflects both category urgency and strong early commercial traction. The company has grown ARR by 1,300% and is recognized as the fastest-growing company in the AI security category. As AI agents proliferate across enterprise environments, Noma's first-mover position in purpose-built AI security positions it to become essential infrastructure for any organization deploying AI at scale.

## Frequently Asked Questions

### What does Noma Security protect?
Noma secures enterprise AI deployments including LLMs, RAG systems, and AI agents with security posture management, application security, governance, and compliance capabilities.

### How fast is Noma growing?
Noma increased ARR over 1,300% in one year and raised $132M total ($32M Series A + $100M Series B) in less than two years since founding.

### Who founded Noma Security?
CEO Niv Braun and CTO Alon Tron founded Noma in 2023 after meeting in the IDF's 8200 intelligence unit. The company came out of stealth in November 2024.

### What specific threats does Noma Security address?
Noma Security addresses the security risks introduced by enterprise AI systems including: data poisoning attacks on training datasets, model file tampering and backdoor insertion, prompt injection in LLM-powered applications, sensitive data leakage through AI model outputs, shadow AI (unsanctioned AI tool adoption), and compliance violations from AI systems processing regulated data without appropriate controls.

### How does Noma's AI Security Posture Management work?
Noma continuously discovers all AI assets in an organization's environment — LLM deployments, ML models, AI APIs in use, training datasets, RAG pipelines, and AI agents. It assesses each asset's security configuration against best practices, generates risk prioritization, and provides remediation guidance. This AI asset visibility is foundational because most enterprises do not have a complete inventory of the AI systems operating in their environment.

### How does Noma Security handle AI agent security?
AI agents introduce unique security risks — they operate autonomously, make API calls, execute code, and access data without per-action human approval. Noma monitors AI agent behavior for anomalous patterns, enforces least-privilege permissions on agent identities, detects prompt injection attempts that could redirect agent actions, and provides audit trails of agent operations for incident investigation and compliance purposes.

### Who competes with Noma Security in the AI security market?
Noma competes with Protect AI, HiddenLayer, and Lakera AI in the AI/ML security space, plus traditional security vendors (Palo Alto, CrowdStrike) adding AI security modules. Noma differentiates on comprehensive coverage across the full AI lifecycle — from data ingestion through model deployment to inference monitoring — rather than focusing on a single layer such as model protection or LLM guardrails.

### How much has Noma Security raised and who are its investors?
Noma raised $132M total — a $32M Series A and a $100M Series B — in under two years since founding in 2023. Investors include Ballistic Ventures, Accel, and Cyber Club London. The 1,300%+ ARR growth in one year reflects rapid enterprise adoption as AI security moved from emerging concern to boardroom priority following high-profile AI system failures.
