Corelight AI

Overview

Corelight AI is a network detection and response (NDR) platform that leverages artificial intelligence and machine learning to analyze network traffic at scale. Designed for security operations centers (SOCs) and threat hunting teams, Corelight AI ingests raw network data, identifies suspicious behavior, and surfaces evidence-backed alerts to help organizations detect and respond to cyber threats faster. The platform is built on the open-source Zeek (formerly Bro) network analysis framework, which ensures deep, protocol-aware visibility into all network communications.

Key Features

• Evidence-Based Detection: Every alert is linked to the raw network evidence that triggered it, enabling analysts to quickly validate and investigate threats without chasing false positives.

• AI-Powered Analytics: Machine learning models analyze network behavior to identify anomalies, lateral movement, and command-and-control communications that traditional signature-based tools may miss.

• Zeek Integration: Native support for Zeek logs provides comprehensive network metadata, including HTTP, DNS, TLS, and file extraction events, giving analysts a complete picture of network activity.

• Threat Intelligence Feeds: Corelight AI ingests threat intelligence from multiple sources, correlating internal network data with known indicators of compromise (IOCs) for real-time threat detection.

• Automated Investigation Workflows: The platform automates common investigation steps, such as threat enrichment and pivoting, to reduce mean time to respond (MTTR).

• Scalable Architecture: Corelight AI can handle high-throughput network environments, processing millions of events per second without dropping packets.

• Custom Detection Rules: Users can write their own detection logic using Zeek scripts or custom signatures to tailor the platform to their specific environment.

• Visualization Dashboards: The platform includes customizable dashboards that provide at-a-glance visibility into network health, top threats, and investigation status.

Use Cases

Threat Hunting

Security analysts use Corelight AI to proactively search for hidden threats within network traffic. By querying historical Zeek logs and applying behavioral analytics, hunters can identify stealthy attackers that evade automated detection.

Incident Response

During an active breach, incident responders rely on Corelight AI to reconstruct the full timeline of network activity. The platform's evidence-based alerts allow responders to quickly pinpoint the scope of compromise and take containment actions.

Network Forensics

After a security incident, Corelight AI supports forensic investigations by providing detailed metadata about every connection, file transfer, and DNS query that occurred on the network. This data can be exported to external analysis tools for deeper inspection.

Compliance Monitoring

Organizations subject to regulations such as PCI DSS, HIPAA, or SOC 2 use Corelight AI to monitor network access and detect policy violations. The platform's comprehensive logs serve as audit-ready evidence for compliance reporting.

Pricing & Plans

Corelight offers a freemium model with a free tier that provides limited network visibility and basic detection capabilities. Paid plans unlock advanced analytics, higher throughput, priority support, and integration with third-party SIEM and SOAR platforms. Specific pricing for enterprise plans is not publicly disclosed and requires contacting the sales team for a custom quote.

Integrations & Compatibility

Corelight AI integrates with major SIEM platforms (e.g., Splunk, Elastic, QRadar), SOAR tools, and threat intelligence platforms. It supports standard log formats (JSON, CSV) and provides REST APIs for custom integrations. The platform is deployed as a SaaS solution or as an on-premises appliance for air-gapped environments.

Who Is It For?

Corelight AI is designed for cybersecurity professionals, including SOC analysts, threat hunters, incident responders, and network security engineers. It is most suitable for mid-to-large enterprises and MSSPs that require deep network visibility and advanced threat detection capabilities.

Limitations

• Corelight AI requires a baseline understanding of network protocols and Zeek to fully leverage its customization features.
• The free tier offers limited throughput and may not be sufficient for high-bandwidth environments without upgrading to a paid plan.
• As a network-based solution, it cannot monitor encrypted traffic unless decryption is configured at the network level.
• The platform's effectiveness depends on the quality of the ingested network data; poor data sources can lead to incomplete visibility.

Final Verdict

Corelight AI is a powerful NDR platform that combines the depth of Zeek-based network visibility with AI-driven analytics to help security teams detect and respond to threats. Its evidence-based approach reduces alert fatigue and accelerates investigations. While it requires some technical expertise and often a paid subscription for full capabilities, it is a strong choice for organizations committed to building a robust network defense capability.
