About

Cotool

The AI Operating System for security teams

Cotool is redefining how Security Operations teams detect and respond to threats by removing the constraints of SIEM-bound, rule-based architectures. Founded in 2025, we’re on a mission to give organizations full detection and response capability across all their security data—wherever it lives and whatever form it takes—without the costs, blind spots, and maintenance burden that have defined the past two decades of SOC tooling. Cotool provides an AI-native detection and response fabric that works across SIEMs, data lakes, EDRs, identity providers, cloud platforms, and SaaS environments. No migrations. No rewrites. No brittle playbooks. Just complete behavioral coverage and automated, cross-platform response delivered through Detection and Response Agents that operate directly on your existing stack.
