Corelight

Corelight is a network detection and response (NDR) company founded by the creators of the open-source Zeek (formerly Bro) network security monitor. Its Open NDR Platform transforms network traffic into high-fidelity security evidence — logs, alerts, and metadata — powering threat detection, hunting, investigation, and incident response across on-premises and cloud environments. Corelight Sensors expose a comprehensive RESTful API for remote configuration and control, driven by the open-source corelight-client command-line client, with a Fleet Manager for centralized fleet management. Backed by Accel and General Catalyst, Corelight is listed on the FedRAMP Marketplace (In Process, Moderate).

Corelight publishes 1 API on the APIs.io network. Tagged areas include Company, Cybersecurity, Network Detection and Response, NDR, and Network Security.

Corelight’s developer surface includes documentation, engineering blog, support, pricing, CLI, authentication, and 14 more developer resources.
