In one paragraph
Artemis Security and Nebulock both appear in this guide's vendor directory. On the autonomy ladder, Artemis Security's own material describes Level 4, Autonomous, human-approved actions and Nebulock's describes Level 3, Continuous hunting, human review. Both state 2 of the twelve capabilities in our matrix. Artemis Security states findings arrive with corroboration or shown working and response actions staged for human approval where Nebulock does not; Nebulock states queries data where it already lives, new rules tested on historical data before release, detection changes kept in version control, names its intelligence sources and publishes an open framework or specification where Artemis Security does not. This guide does not pick a winner; which differences matter depends on your must-haves.

Where do Artemis Security and Nebulock differ?
Artemis Security states, Nebulock does not publish
- Findings arrive with corroboration or shown working: Correlates identity, cloud, endpoint and SaaS signals during autonomous investigation.
- Response actions staged for human approval: Response actions are staged and require human confirmation.
Nebulock states, Artemis Security does not publish
- Queries data where it already lives: Helix federated search "to get data just-in-time, not just-in-case".
- New rules tested on historical data before release: "Every detection rule must pass a Retrohunt before deployment."
- Detection changes kept in version control: Rules exported to GitHub, with immutable version history, compare and revert.
- Names its intelligence sources: Intel from CrowdStrike, Mandiant, MISP and community feeds.
- Publishes an open framework or specification: Agentic Threat Hunting Framework and Agentic Detection Engineering Framework on GitHub, MIT license.
Both state
Hunts start without a per-hunt request, Maps hunts or detections to MITRE ATT&CK
Neither states
States MCP support, States a security attestation, Publishes a list price

Which should you look at first?
Look at Artemis Security first if your must-haves include findings arrive with corroboration or shown working or response actions staged for human approval.
Look at Nebulock first if your must-haves include queries data where it already lives or new rules tested on historical data before release.
Either way, put both through the same trial questions, and try the calculator with your own must-haves.
