Company Overview

Dune Security’s User Adaptive Risk Management solution proactively prevents insider threats and social engineering by simulating multi-channel attacks, scoring user risk, and adapting training and controls in real time. Powered by AI, we quantify employee risk with comprehensive data and automatically deliver user‑adaptive training and intervention. For higher‑risk users, our platform integrates seamlessly with the broader security stack to dynamically implement controls.

Backed by Craft Ventures, Toba Capital, Alumni Ventures, Fire streak Ventures, and Antler, we empower CISOs to proactively manage human risk—the leading cause of cybersecurity breaches—and build safer, more resilient organizations.
