Intel to detection weight 20%
Nebulock is stronger
Artemis Security 3 / 5Nebulock 5 / 5
Artemis Security: Hunts draw on 100+ intelligence feeds and detections are written automatically; the route from a new report to a tested rule is not described.
Nebulock: The vendor states its Vespyr agent turns a threat intel report into a deployable detection in minutes, with intel from CrowdStrike, Mandiant, MISP and community feeds.
Continuous hunting weight 20%
Nebulock is stronger
Artemis Security 4 / 5Nebulock 5 / 5
Artemis Security: Runs continuous hunts daily against a growing library, plus ad hoc hunts described in natural language.
Nebulock: Built to hunt continuously; hunts run without a directive and follow the published four-stage LOCK framework.
ATT&CK coverage weight 8%
Level
Artemis Security 3 / 5Nebulock 3 / 5
Artemis Security: Claims comprehensive MITRE coverage from day one; we found no public coverage view.
Nebulock: Hypotheses map to ATT&CK and the docs reference a MITRE Coverage feature; public pages do not show how coverage is measured.
Rule lifecycle weight 7%
Nebulock is stronger
Artemis Security 2 / 5Nebulock 5 / 5
Artemis Security: Detections are written and tuned automatically; no testing, versioning or review workflow is described.
Nebulock: Every rule must pass a retrohunt before deployment, with immutable version history, compare and revert, and GitHub export.
Data reach weight 25%
Nebulock is stronger
Artemis Security 3 / 5Nebulock 4 / 5
Artemis Security: 225+ connectors, but detection-critical hot-path data is ingested; only high-volume data is queried where it lives.
Nebulock: Federated search fetches data just in time; docs name EDR, identity and cloud sources plus Microsoft Sentinel, with fewer data lakes named than Mars Security or Anvilogic.
Transparency weight 5%
Level
Artemis Security 3 / 5Nebulock 3 / 5
Artemis Security: No public price; the full connector list and a stated timeline (connectors live in under an hour, real cases inside 48 hours) are published.
Nebulock: No public price, but a public documentation site and MIT-licensed frameworks on GitHub.
Time to first value weight 15%
Level
Artemis Security 4 / 5Nebulock 4 / 5
Artemis Security: States connectors go live in under an hour and real cases arrive inside 48 hours; ingests hot-path data.
Nebulock: SaaS with documented integrations; no published time-to-value figure.
Editorial assessment, 1 to 5 per criterion, from public vendor material. It measures fit for turning threat intelligence into hunts and detections on data a team already has. It is not a measure of overall product quality.
