Fortune 500 CISOs vote Rein the best AI cybersecurity solution at ONUG 2026

Here's why >

THE PART WHERE WE TELL YOU OUR MISSION

Keeping Enterprise Agents Safe.

  • How it Started

    Our story starts with two friends with long cybersecurity careers asking one question: what massive problem is everyone ignoring?

  • What We Realized

    The industry was policing employees’ ChatGPT and devs’ coding assistants. But Enterprise Agents – the ones that actually run the business – moving money, touching crown jewels – had no real security at all.

  • The Big Discovery

    The missing piece wasn’t another gateway. It wasn’t another proxy. It was the one thing nobody else was building: security that lives inside the application, with full execution context, designed for the agents that actually run the business. So we built it. That’s when Rein was born.
