Niv Braun

Niv Braun is co-founder and CEO of Noma Security, a Tel Aviv, Israel, company that finds and blocks security risks in AI applications and agents. He met his co-founder, chief technology officer Alon Tron, in Unit 8200, the Israeli military’s signals intelligence unit, and the two started Noma in 2023.

A blind spot in data science work

Braun’s founding argument is that data engineering and machine learning teams work apart from software developers, so the application security tools a company already owns never see their notebooks, data pipelines, or downloaded open-source models. In a Help Net Security interview he said application security teams “have no visibility into their work” even though they are expected to secure it. “The first step to implementing governance controls and securing the new AI attack surface is visibility,” he said.

From the AI lifecycle to agents

Noma came out of stealth in November 2024 and widened its focus from models and pipelines to AI agents in production. Braun has warned that confidential data used to train or fine-tune a model can be pulled back out through prompt injection or jailbreaks, and that runtime monitoring has to watch both prompts and responses.

In July 2025 the company announced a $100 million round led by Evolution Equity Partners, with plans to grow its research team in Tel Aviv. “AI agent adoption is exploding within our customer base,” Braun said at the time.
