Stellar Cyber develops an Open XDR (Extended Detection and Response) platform that consolidates security data from multiple sources to provide comprehensive threat detection and response capabilities. The platform ingests data from network security tools, endpoint security solutions, firewalls, identity tools, cloud security products, and other security infrastructure to create unified visibility across an organization's entire attack surface.

The platform emphasizes data normalization and correlation across disparate security tools, using machine learning to baseline normal behavior and identify anomalies. Rather than relying solely on rule-based detection, the system applies artificial intelligence to reduce alert volumes from potentially millions of events down to actionable incidents. For example, the platform can analyze IDS alerts and use behavioral analytics to filter out false positives based on factors like normal login times, locations, and session durations.

Stellar Cyber's architecture is API-driven and designed to integrate with existing security investments, avoiding vendor lock-in. The platform includes capabilities for threat hunting, network detection and response (NDR), and next-generation SIEM functionality. It serves both enterprise customers and managed security service providers (MSSPs), enabling security operations centers to correlate complex, multi-dimensional attacks across network traffic, endpoints, applications, and cloud environments. The system aims to help SOC teams scale their operations by automating pattern recognition and allowing analysts to focus on strategic security work.
