What does deployment look like?
Corelight's Open NDR Platform is designed to deploy flexibly across Security Operations Center (SOC) environments without disrupting existing infrastructure. Sensors can be deployed as physical appliances, virtual machines, software, or cloud-native instances, ingesting traffic from TAPs, SPAN ports, firewalls, and cloud packet mirroring. This approach provides consistent network visibility across on-prem, hybrid, cloud, and air-gapped environments, while integrating cleanly with existing SOC tools and workflows.
What is Network Detection and Response (NDR)?
Network Detection and Response (NDR) is a cybersecurity solution that continuously monitors network traffic across physical and cloud environments, giving security teams the visibility and insights needed to quickly detect and respond to threats. As attackers adopt AI-powered and more sophisticated techniques, organizations are increasingly deploying NDR to help identify novel attacks and sophisticated threats that traditional tools often miss. NDR platforms deliver detections, network telemetry, packet capture, and other valuable data all from a unified view.
How do I evaluate NDR vendors?
When evaluating an NDR solution, focus on a few core factors that determine real-world effectiveness.
Transparency
Look for clear visibility into data sources and detections so teams can tailor investigations to their environment.
Seamless integration
NDR platforms that integrate smoothly and enhance your existing SOC tools can strengthen workflows without disruption.
Data quality and breadth
High-fidelity, comprehensive network data enables confident detection and investigation, and can enhance the performance and accuracy of other AI-powered cybersecurity tools.
Expert support
Responsive human expertise helps teams get the most value from their NDR investment.
Prioritizing transparency, integration, data quality, and support ensures an NDR solution that strengthens your
security posture.

WHY DOES NETWORK VISIBILITY MATTER MORE NOW?
As attackers increasingly evade perimeter defenses and endpoint detection, the network has become the most reliable source of truth. NDR shows what actually happened—across users, devices, applications, and cloud workloads — even when threats blend in or leverage legitimate tools.
High-fidelity network evidence gives security teams the context needed to investigate incidents faster, validate alerts,
and respond confidently in complex hybrid environments.

WHAT ROLE DOES NETWORK VISIBILITY PLAY IN SOC WORKFLOWS?
Corelight integrates seamlessly with the tools SOC teams already rely on, including SIEM, EDR, SOAR, and threat intelligence platforms. By supplying high-fidelity, network-native evidence, Corelight enriches alerts, improves correlation, and adds critical context across the security workflow. This allows teams to get more value from their existing tools while working from a shared, trusted source of truth.
