Cotool provides an AI-powered security operations platform that automates detection engineering, threat hunting, and incident investigation workflows. The platform uses customizable AI agents that can author and tune detection logic automatically, reducing the manual effort required for rule writing and improving security coverage across SecOps tools. The platform offers three core capabilities: detection building and tuning, investigation automation, and threat hunting. For detection, the system converts detection rules into autonomous agents that refine themselves and identify gaps in baseline security coverage. The investigation automation feature allows security teams to build and deploy agents that monitor, triage, investigate, and tune detection as code, transforming manual workflows into automated processes. These agents can be combined with co-pilot functionality to assemble context across multiple tools and accelerate investigation timelines. For threat hunting, Cotool agents continuously monitor threat intelligence and system activity, automatically initiating hunts based on new threats, anomalies, or custom triggers. The platform enriches indicators across multiple sources to surface exposure and enables seamless pivoting into detection authoring. The system is designed to help security teams reduce mean time to response (MTTR) and manual alert handling through fully customizable response workflows, while building a library of agents tailored to specific team needs and runbooks.
