Detect what static rules can’t
Purpose-built to detect threats your SIEM is missing. Cotool detects threats using natural language intent, and automatically suggests new detections to cover gaps.

Detect threats that can't be written as rules
Detection agents enable intent-driven coverage. Describe your threat model in natural language and Cotool agents constantly scour your environment – even tools you don’t have central log visibility into. Capture multi-step attacks, statistical signals, and unstructured data sources that can’t be expressed within a static rule.
“Detection used to mean manually stitching data across a dozen tools. Now Cotool continuously strengthens our coverage on its own.”
Extend existing coverage
No need to throw out your existing SIEM rules. Create new rules in an AI-assisted detection authoring experience where agents pull context from any tool and iterate until the rule is production-ready. Apply the same agents to your existing ruleset to tune automatically. All compatible with your existing detection-as-code infrastructure.
Visualize your coverage gaps and fix them automatically
Map your entire detection suite across sources onto the MITRE ATT&CK framework to monitor coverage and surface gaps. Create new contextualized detections for any tactic and technique with one click.

Agent observability built-in
Every Detection Agent run is logged and searchable. Re-enter any execution to view all tool inputs and outputs and ask follow up questions.
Suggested detections out of the box
Review a library of Detection Agents and rules tailored to your environment. Agents continuously perform threat hunts to produce relevant detection suggestions around the clock.
Environment Understanding
Cotool proactively maps the data in your environment upon connection to build a context layer shared by every agent.
Evaluation & Monitoring is First Class
Cotool’s evaluation harness automatically measures every agent run so you can track agent performance over time. Agent version control keeps the lineage clear.
Enterprise ready
SOC2 Type 2 Certified, with Audit logging, RBAC, and SSO support out of the box.
“It's enabled us to comfortably onboard new log sources and write rules around them without worrying that we're going to cause alert fatigue for the human detection engineers and analysts on the team.”
