Cotool

Cotool is an AI agent platform for security operations teams, built to handle detection, response, and threat hunting across a security stack. It addresses problems such as stale detection rules, accumulating alerts, brittle automations, and the added pressure of AI-enabled attackers, aiming to automate routine work so teams can focus on higher-priority threats.

The platform centers on three modules: Detect, which lets users describe a threat model in natural language and continuously hunts across the environment, including tools without centralized log visibility; Respond, which automates response from any alert source, supports natural-language agent creation, includes human-in-the-loop controls, and tunes detections to reduce false positives; and Hunt, which monitors threat intelligence from configured sources and the public web, filters for relevance, checks exposure, and proposes new detections. Additional capabilities include an AI chat for investigations that can be converted into always-on agents, an evaluation harness with agent version control, and agent memory that improves over runs with suggestions for low-performing agents.

Cotool is aimed at security operations and detection engineering teams. Access is arranged through a demo booking process; the pages do not specify plan tiers, trials, or pricing models.
