In one paragraph
Cotool and Mars Security both appear in this guide's vendor directory. Both vendors' own material describes Level 3, Continuous hunting, human review. Both state 3 of the twelve capabilities in our matrix. Cotool states detection changes kept in version control and states MCP support where Mars Security does not; Mars Security states queries data where it already lives, new rules tested on historical data before release, findings arrive with corroboration or shown working and states a security attestation where Cotool does not. This guide does not pick a winner; which differences matter depends on your must-haves.

Where do Cotool and Mars Security differ?
Cotool states, Mars Security does not publish
- Detection changes kept in version control: Compatible with existing detection-as-code infrastructure; agent version control.
- States MCP support: Custom MCP listed among integrations.
Mars Security states, Cotool does not publish
- Queries data where it already lives: "Hunt across every log source, cloud, and endpoint without moving a byte."
- New rules tested on historical data before release: Each rule is backtested against 30 days of the customer's own data before it goes live.
- Findings arrive with corroboration or shown working: Hands analysts "a corroborated shortlist rather than a scored queue".
- States a security attestation: SOC 2, per its September 2026 announcement.
Both state
Hunts start without a per-hunt request, Maps hunts or detections to MITRE ATT&CK, Names its intelligence sources
Neither states
Response actions staged for human approval, Publishes an open framework or specification, Publishes a list price
