About Corelight

Corelight sells the Open NDR Platform, which transforms network data into evidence. Corelight says that evidence powers AI-driven detection and expert-authored workflows.

Corelight sensors capture a copy of all traffic out-of-band. The sensor then deduplicates and cleans the data, discarding redundant multicast traffic. Powered by Zeek, the sensor performs deep protocol parsing across 70+ data types. The resulting evidence is routed to Corelight Investigator, a SIEM, or a data lake for long-term forensics.[9]

Investigator is Corelight's SaaS-based NDR platform. Corelight says it streamlines complex investigations by eliminating repetitive review steps and enables up to 10x faster triage. Agentic Triage uses transparent, expert-written playbooks to follow consistent triage logic for every investigation. SIEM Verdict Export sends every triage verdict, including the reasoning chain, evidence links and recommended next steps, directly into the customer's SIEM. Investigator also offers host isolation, IP blocking and identity actions through integrated EDR, firewall and identity provider workflows.[1][10]

Corelight fuses machine learning, behavioral analytics and curated signatures in its threat detection. AI/ML detection is a subscription-based module that can be purchased with Corelight Sensors, and AI/ML models are enabled, managed and tuned through Fleet Manager. Many of these detections run directly on-sensor, with no cloud dependency. Threat Intelligence is a licensed feature for Corelight Sensors and Investigator, and it is supported on all sensor options. Corelight Smart PCAP links Zeek logs, detections and extracted files to only the packets needed for investigations.[8][11][12][13]

For cloud environments, Corelight Cloud Sensors are available for AWS, GCP and Azure. Corelight supports AWS, Azure and GCP native packet mirroring, and third-party packet brokers. Performance and Asset Visibility is a Corelight Open NDR module that passively extracts asset classification and network performance telemetry from traffic the sensors are already collecting.[14][15]

Corelight also sells services. Corelight says it can provide a resident engineer to work alongside a customer's team, and services can be purchased standalone or bundled with the platform. Corelight describes integrations with Splunk Enterprise Security and Splunk SOAR, and with Microsoft Defender, Microsoft Sentinel and Microsoft Entra ID.[1][2][10][12][14][16]
