Nebulock raises $25M to expand hunt-first security platform
Threat hunting startup Nebulock Inc. revealed today that it has raised $25 million in new funding to push its autonomous hunting platform into broader “hunt-first” security analytics.
Founded in 2023, Nebulock offers autonomous, vendor-agnostic threat hunts driven by artificial intelligence. Those hunts span endpoint, identity, cloud, network and software-as-a-service telemetry. Its argument is simple: Most security tooling judges events one at a time, so it misses threats that only surface once activity is read as a sequence over time.
The company calls the resulting risks “green flags,” its term for malicious activity that looks routine on the surface. An attacker logging in with valid stolen credentials, or a sanctioned AI agent doing something nobody authorized, trips no rule and raises no obvious anomaly. Nebulock turns an organization’s own telemetry into what it describes as a behavioral system of record, letting analysts reason across systems rather than chase individual alerts.
Nebulock said the platform has run more than 300 million agentic investigations and produced more than 4,000 high-confidence findings since its public launch less than a year ago. Customers include Cribl Inc., HealthEdge Software Inc. and Bain Capital LP, alongside Fortune 500 enterprises in financial services, healthcare and technology.
