Their own description (from YC)

Cotool builds AI agents and the infrastructure around them to help security teams detect threats, investigate alerts, hunt for attacks, and respond.

Our agents work across a team's security tools and data. They investigate alerts, write and tune Python detections, and turn threat intelligence into hunts and new coverage. Teams can customize agents around their workflows, inspect the evidence, edit detection logic, and bring humans in when judgment or approval matters.

Underneath the agents, Cotool provides log storage and search built for their workloads, with access to data where it already lives. The goal is to give security teams more capacity to defend their companies as their environments and workloads grow.

Teams at Ramp, EliseAI, ClickHouse, Legora, and many more use Cotool.
