Corelight Open Network Detection and Response

Corelight Open Network Detection and Response provides scalable, open network traffic analysis and threat defense designed to protect complex hybrid enterprises against modern cyberattacks, ransomware outbreaks, and sophisticated network intrusions. Built upon open standards Zeek and Suricata, Corelight provides comprehensive network evidence without proprietary vendor lock-in.

The platform deploys across physical network tap aggregators, hypervisors, and cloud VPC traffic mirroring points, capturing traffic up to 100 Gbps per appliance. Core technical capabilities encompass deep protocol dissection for DNS, HTTP, SSL/TLS, SSH, SMB, and Kerberos, automated signature-based threat detection, machine-learning-based encrypted traffic profiling, automated file extraction for sandbox analysis, and high-speed streaming into modern data architectures via Kafka, Syslog, or S3. Because data is structured and normalized, it dramatically reduces SIEM ingestion volumes and storage costs.

Critical infrastructure operators, financial institutions, and global technology organizations implement Corelight Open Network Detection and Response to modernize their security monitoring capabilities. It integrates seamlessly with Splunk, Microsoft Sentinel, Amazon OpenSearch, and SOAR automation engines. Typical operational use cases include detecting insider data exfiltration across corporate network boundaries, tracking adversary lateral movement across Active Directory environments, providing comprehensive network forensic audit trails, and verifying the reach of active security incidents during breach containment.
