Securing the Apps Everyone Is Building with Roi Nisimi and Yonatan Levi

What happens when your marketing team, your sales team, and the person down the hall can all ship a full app from a single prompt? And what is that app quietly connected to? In this episode, Ron sits down with Roi Nisimi, Principal Security Researcher, and Yonatan Levi, AI Security Researcher, of Orca Security. They built apps on the most popular AppGen platforms and then tried to break into them.

Ron, Roi, and Yonatan get into what's really running behind a prompt-built app, and what Orca's team found when they went looking for trouble. In one case, a single misconfigured app gave them a way into every integration connected to the workspace. They also explain why Supabase has become a favorite of builders and attackers alike, and share the security questions they ask before sending a prompt.

The bigger tension is speed. With no code review between the prompt and production, Roi argues that velocity has broken the threat models that security relied on for years. And when the agent makes every decision, nobody fully understands what was built, not even the security researchers.
