Cotool is an AI agent platform designed for security operations teams to automate detection engineering, investigations, and threat hunting workflows. The platform enables teams to build and deploy customizable AI agents that operate autonomously across SecOps tools. The detection capabilities allow agents to author and tune detection logic automatically, converting detection rules into autonomous agents that refine themselves and identify coverage gaps. This reduces manual rule writing and improves detection coverage across security stacks. For investigations, the platform provides agents that monitor, triage, investigate, and tune detection as code. Teams can build a library of agents tailored to their specific runbooks and workflows. The system combines agents with co-pilot functionality to assemble context across tools and accelerate investigation processes, reducing mean time to respond and manual alert handling. The threat hunting functionality enables continuous monitoring of threat intelligence and system activity. Agents automatically initiate hunts based on new threats, anomalies, or custom triggers. The platform enriches indicators across multiple sources to surface exposure and allows teams to pivot into detection authoring. The platform is built around the concept of detection as code, with fully customizable response workflows that can be adapted to specific team requirements and operational procedures.
