FAQ
How does the Open NDR Platform integrate with other cybersecurity tools?
Corelight's Open NDR (network detection and response) Platform integrates with your security ecosystem by providing native, out-of-the-box connectors for all leading SIEM, XDR, SOAR, and cloud platforms. For custom pipelines, the platform features high-performance data exporters that stream AI-ready evidence to multiple destinations. Finally, the Logs API and MCP server enable programmatic access for custom orchestration and management, ensuring network evidence can be leveraged by any tool in your SOC stack.
SIEM Verdict Export integration pushes complete Agentic Triage verdicts, including reasoning chains and evidence, directly into your SIEM. This streamlines the path between AI-powered investigation and your existing analyst workflows. The Corelight Agent Builder Library also extends integration by giving teams exportable, expert-authored investigation knowledge they can ingest into their own AI agents, SOAR workflows, or private LLM environments.
What are the key criteria for evaluating modern NDR platforms?
A modern NDR platform must be evaluated on five key criteria: Data Quality (AI-ready forensic evidence, not shallow metadata); Unified Visibility (hybrid and "east-west" traffic); Explainable Detections (no black box engine); Accelerated Response (AI-assisted workflows that link alerts to evidence and lower MTTR); and SOC Modernization & ROI (tool consolidation, open integration with SIEM/XDR, and 24/7 expert support)
What tools does Open NDR help consolidate?
Corelight's Open NDR Platform is engineered for 4:1 tool consolidation, streamlining operations by eliminating the need for separate, siloed tools. Open NDR combines the functionality of four critical tools into a single, unified platform: Network Security Monitoring (NSM) for rich metadata (powered by Zeek), an Intrusion Detection System (IDS) for alerts (powered by Suricata), Static File Analysis for malware (powered by YARA), and intelligent Packet Capture (Smart PCAP) for deep forensic evidence.
Who can use Open NDR?
Open NDR provides AI-powered summaries and workflows that simplify Tier 1 triage, enabling junior analysts to operate with confidence. For threat hunters, it delivers rich, interconnected raw data and advanced querying capabilities. Open NDR's unified context accelerates incident response by up to 95%, giving security teams of all sizes (from Fortune 500 companies to growing operations) the flexible and scalable deployment options needed to disrupt advanced attacks.
