Nebulock is the first agentic threat hunting platform; autonomously surfacing behaviors, not just IOCs, from your existing data.

Nebulock acts like a new teammate: a 24/7 AI threat hunter that investigates hypotheses, reasons through your telemetry, and learns from your environment. Whether you’re a two-person SOC or a global enterprise, we scale your threat hunting—and give your team superpowers.

Today, threat hunting is broken. Security teams spend weeks chasing alerts, writing detections by hand, and manually validating findings—often just to confirm what their existing tools already flagged. Meanwhile, attackers exploit credentials, move laterally, and operate in silence.

Nebulock flips the model.

We continuously and autonomously hunt across endpoint, identity, and cloud telemetry—identifying the subtle behavioral signals that point to credential misuse, lateral movement, insider threats, and post-access activity. Then we turn those hunts into hardened, behavior-based detections—automatically.
No new agents
No alert regurgitation
No workflow disruption

Just high-fidelity, explainable findings—delivered directly to your SIEM, API, or Slack.
