In one paragraph
Nebulock and Vega both appear in this guide's vendor directory. On the autonomy ladder, Nebulock's own material describes Level 3, Continuous hunting, human review and Vega's describes Level 2, Directed autonomous hunts. Both state 4 of the twelve capabilities in our matrix. Nebulock states hunts start without a per-hunt request, new rules tested on historical data before release and names its intelligence sources where Vega does not; Vega states findings arrive with corroboration or shown working and states MCP support where Nebulock does not. This guide does not pick a winner; which differences matter depends on your must-haves.

Where do Nebulock and Vega differ?
Nebulock states, Vega does not publish
- Hunts start without a per-hunt request: "Vespyr hunts without a directive."
- New rules tested on historical data before release: "Every detection rule must pass a Retrohunt before deployment."
- Names its intelligence sources: Intel from CrowdStrike, Mandiant, MISP and community feeds.
Vega states, Nebulock does not publish
- Findings arrive with corroboration or shown working: "Every step of the hunt shows its work."
- States MCP support: MCP support.
Both state
Queries data where it already lives, Detection changes kept in version control, Maps hunts or detections to MITRE ATT&CK, Publishes an open framework or specification
Neither states
Response actions staged for human approval, States a security attestation, Publishes a list price

Where does each run, and what controls does it describe?
Nebulock
- SaaS. Helix federated search "to get data just-in-time, not just-in-case".
- Integrations: Okta, Microsoft Entra, Duo, CrowdStrike, Microsoft Defender, SentinelOne, AWS CloudTrail, Microsoft Event Hub, Microsoft Sentinel, vulnerability tools (beta), Jamf, Slack, Microsoft Teams, Tines, Jira, GitHub.
- Intel from CrowdStrike, Mandiant, MISP and community feeds.
- "Every detection rule must pass a Retrohunt before deployment."
- Rules edited via chat or direct SQL, exported to GitHub, with immutable version history, compare and revert.
Vega
- Federated analytics that queries every source in place: "No migration, ingestion, or egress."
- MCP support. The connectors page does not name individual connectors. A sandbox is offered at sandbox.vega.io.
- "Every step of the hunt shows its work."
- "Detections live in source control, reviewed like any other code change"; "Every change has a diff, an author, and an approver."
Which should you look at first?
Look at Nebulock first if your must-haves include hunts start without a per-hunt request or new rules tested on historical data before release.
Look at Vega first if your must-haves include findings arrive with corroboration or shown working or states MCP support.
Either way, put both through the same trial questions, and try the calculator with your own must-haves.
