Noma Security, a startup focused on keeping AI agents in check, just closed a $100 million Series B round, less than a year after emerging from stealth and raising its last round. Led by Evolution Equity Partners with continued backing from Ballistic Ventures and Glilot Capital, the investment reflects surging demand for AI agent security oversight.

Governance platform for autonomous tools sees investment support as AI agents take over

Noma’s platform helps enterprise security teams govern the increasingly autonomous tools now embedded in everything. Everything from marketing workflows to customer service and DevOps. As AI agents gain more autonomy to act, whether issuing refunds or executing production code, the associated risks also multiply.

“We are intimately familiar with the AI security category and chose to invest in Noma Security based on two main factors,” said Richard Seewald, founder and managing partner, Evolution Equity Partners. “First, the Noma Security founding team had the foresight to build a comprehensive AI security and governance platform to address all CISO challenges related to AI security. Second, as evidenced by rapid customer growth, Noma Security quickly found product-market fit within the enterprise CISO’s organization with a solution for agentic AI security and governance.”

Real-time visibility into agent behavior

While many companies are busy building AI agents, Noma’s focused on keeping them in line. Its platform helps enterprises spot risks, set up security and governance guardrails, and monitor AI agents across cloud environments, code repositories, and dev platforms—basically, wherever those agents live and work.

One of Noma’s customers processes hundreds of millions of AI prompts every month while scanning thousands of environments to keep tabs on everything the agents are doing.

“Traditional AI security risks are substantially magnified with the autonomy and capability of AI agents,” said Niv Braun, co-founder and CEO, Noma Security. “When an agent can release and run code in production, or give refunds to customers, cybersecurity teams must take caution.”

Growth, traction, and what’s next

Since emerging from stealth in November 2024, Noma has seen rapid traction, citing a 1,300% increase in annual recurring revenue and adoption across various industries, including financial services, life sciences, retail, and big tech.

“AI agent adoption is exploding within our customer base, and CISOs understand that AI innovation must be thoughtfully deployed with full guardrails,” said Braun. “Noma Security is the only cybersecurity vendor to offer an end-to-end platform purpose-built to identify and mitigate the uniquely advanced risks of agentic AI.”

Richard Seewald of Evolution Equity Partners added, “The timing, team and technology are all aligned.”

With this new round, Noma plans to expand its go-to-market efforts in North America and EMEA, as well as grow its R&D and engineering teams in Tel Aviv. The company is positioning itself to meet a growing market of enterprise CISOs looking to operationalize AI securely, before the agents they deploy start making decisions that humans can’t trace back.
