Noma Security Raises $100M to Tackle the Next Frontier of AI Risk: Agent Security

In a funding milestone that signals a seismic shift in enterprise AI defense, Noma Security has raised a jaw-dropping $100 million Series B—less than a year after its last round—cementing its status as the fastest-growing contender in the AI security space. The round was led by Evolution Equity Partners, with continued backing from Ballistic Ventures and Glilot Capital, as the industry’s appetite for securing agentic AI hits a boiling point.

Coming out of stealth just nine months ago, Noma has catapulted from early adopter curiosity to essential enterprise infrastructure. Annual recurring revenue exploded by over 1,300%, fueled by traction across financial giants, biotech powerhouses, and cloud-native titans. The startup’s meteoric rise reflects a larger reality: AI agents aren’t coming—they’re already here.

And with them, a new class of risk.

From Black Box to Black Ops

Noma isn’t just another AI security player patching holes in large language models. The company is laser-focused on the uniquely thorny risks of agentic AI—intelligent systems that can reason, make decisions, and autonomously act across digital environments. Think of them less like chatbots and more like interns on digital steroids. With autonomy, however, comes unpredictability—and exposure.

“AI agent adoption is exploding within our customer base,” said Niv Braun, CEO and co-founder of Noma Security. “CISOs understand that AI innovation must be thoughtfully deployed with full guardrails.”

That demand for “guardrails” isn’t theoretical. One of Noma’s customers reportedly handles hundreds of millions of AI prompts monthly, scanning everything from model artifacts to code repositories and dev platforms. The attack surface isn’t just growing—it’s metastasizing.

Security at Agent Speed

Unlike traditional AI security vendors that bolt tools onto existing workflows, Noma built its architecture from the ground up to manage the full lifecycle of AI agents. That includes real-time visibility into decision-making processes, contextual anomaly detection, and policy enforcement that spans cloud to code. It’s governance and compliance on agent speed—and scale.

“We chose to invest in Noma based on two main factors,” said Richard Seewald, founder and managing partner at Evolution Equity Partners. “First, the founding team had the foresight to build a comprehensive AI security and governance platform to address all CISO challenges related to AI. Second, Noma quickly found product-market fit within the enterprise CISO's organization.”

Betting Big on Governance-First AI

While most of the AI gold rush is focused on boosting productivity or slashing costs, Noma is doubling down on the infrastructure that keeps that promise from becoming a liability. UBS Research recently found that over half of organizations plan to adopt agentic AI by 2026—and 83% by 2028. That gives security leaders precious little time to build frameworks that can detect when AI agents deviate, misfire, or get manipulated.

Noma’s answer is a unified platform that doesn’t just secure models but governs behavior—offering CISOs a rare mix of visibility, control, and adaptability.

Now, with $100 million in fresh capital, Noma plans to scale across North America and EMEA, while beefing up its product and research footprint in Tel Aviv, already one of the world’s hottest cybersecurity R&D hubs.

“In partnership with our customers and investors, we’ve built the most comprehensive security and governance solution for both AI and agents,” Braun said. “We’re thrilled to continue leading the enterprise AI security category and help our customers deliver AI innovation with confidence.”

As enterprises inch closer to AI autonomy, it’s clear that security can’t lag behind. Noma’s next-gen platform might just be the firewall between safe automation—and an AI-fueled catastrophe.
