What is NDR?

Network detection and response (NDR) is a cybersecurity technology that continuously monitors network traffic from physical and cloud-based environments. NDR solutions include extended visibility, enriched network data, detection, threat hunting, forensics and response capabilities. These solutions are often delivered as a combination of physical, virtual, software, and cloud appliances. It enables security teams to more quickly detect adversary activity and respond to security incidents.

What is evidence-based security?

It is an approach that relies on a comprehensive and context-rich network data, serving as the single source of truth for all security operations. This high-fidelity evidence, built on the open-source Zeek standard, provides unparalleled breadth by capturing every connection (including from blind spots like East-West and encrypted traffic). Evidence helps accelerate SOC workflows and serves as an immutable historical record for threat hunting and compliance, while reducing false positives.

What is Corelight’s AI-powered security platform?

An AI-powered SOC leverages artificial intelligence and machine learning to enhance threat detection, streamline security operations, and create a more robust security ecosystem. This advanced approach moves beyond traditional, human-centric models to address the increasing volume and sophistication of cyber threats.

How can I reduce false positives?

Combating false positives requires a proactive approach to detection. Here's a practical checklist to help your team reduce noise and increase confidence in your security tools.
Implement a multi-layered detection strategy: Avoid over-reliance on a single type of detection. By combining different methodologies—like signature-based rules, behavioral analysis, and threat intelligence—you can create a more comprehensive security posture. This approach allows each detection method to compensate for the inherent gaps of another, increasing the overall confidence in an alert. When an alert is triggered by more than one independent detection method, its legitimacy is significantly higher.
Prioritize high-fidelity data: Move beyond low-fidelity sources like NetFlow and firewall logs. Invest in tools that provide rich, contextual network evidence like Zeek® logs.
Tune your rules regularly: Continuously review and refine your detection rules and signatures. Regularly audit your most common alerts and suppress or adjust the rules that lead to false positives.
Use behavioral analysis: Supplement signature-based detections with machine learning and behavioral analysis. These methods can help identify anomalous activity that traditional rules might miss.
Establish a feedback loop: Create a streamlined process where analysts can easily provide feedback on false positives. This feedback is critical for informing detection engineering and rule tuning. To make this process more effective, ensure your team understands the value of red and purple team exercises for testing and validating your detection rules against real-world attack simulations.
Focus on detection engineering: Dedicate time and resources to creating custom detections tailored to your specific environment. This allows you to hunt for specific threats and reduce generic alerts.
Leverage contextual enrichment: Ensure your security tools are integrating with other sources (like threat intelligence, asset management, and user data) to provide a complete picture for every alert and correlation for higher confidence in alerts.

Why Corelight

[H1] Threat detection
Illuminate and disrupt evasive attacks now reimagined with Agentic Triage. Detect advanced threats and automatically transform alerts into evidence-backed investigations with Open NDR built on forensic-grade network telemetry and explainable Agentic Triage.

[H2] Multi-layered detections
Corelight delivers a comprehensive suite of network security analytics that helps organizations identify more than 100 adversarial TTPs across the MITRE ATT&CK® spectrum. Corelight collects and analyzes contextual data and applies a multi-layered detection strategy that combines AI and machine learning, behavioral analytics, curated signatures, along with threat intelligence to deliver prioritized aggregated alerts based on risk.
Only Corelight provides explainability for machine learning detections and leverages the power of the global open-source community to deliver curated Zeek-based behavioral detections while providing detailed logs for hunting an attacker's trail with precision.

[H2] AI for Threat Detection — and AI for Investigation
Corelight’s AI/ML-powered detection engine uses supervised and unsupervised models to uncover advanced, evasive, and novel threats. Our models are customizable and never trained on customer data.
Beyond scoring alerts, Agentic Triage executes expert-authored investigative playbooks to validate detections with contextual network evidence.

Corelight’s AI powered SOC

[H2] Move from alert to decision—faster

[H3] EDR evasion and encrypted traffic coverage
Detect post-exploitation behavior and threats that evade endpoint controls—such as credential access, DNS tunneling, or anomalous SMB usage. See and detect across east-west traffic, unmanaged devices, and encrypted sessions, where EDR often has blind spots.

[H3] High-fidelity, low noise alerts
Targeted detections for high-value threat behaviors like lateral movement, C2 communication, encrypted traffic misuse, and exfiltration that are precise and context-aware - dramatically reducing false positives.

[H3] Automated triage with agentic AI
Agentic Triage consolidates related alerts into entity-centric investigations, automatically assembling evidence and producing defensible verdicts with visible reasoning.

[H2] Faster triage, quicker response with explainable AI
Corelight enriches detections with structured, AI-driven investigative workflows. Instead of manually correlating alerts, analysts receive:
Pre-investigated entity cases
Behavioral timelines
Evidence-backed summaries
Clear next-step guidance
Transparent reasoning behind every conclusion
See the “why” behind every threat—so you can validate, contain, and respond with confidence.
