Stellar Cyber

Stellar Cyber is a cybersecurity company that provides an open Extended detection and response (XDR) (Open XDR) platform for threat detection, investigation, and response across enterprise environments.

• Open XDR platform for centralized threat detection, investigation, and response across networks, endpoints, cloud, and users.
• Security data ingestion and normalization from multiple tools and data sources for unified Security Operations (SecOps).
• Behavioral analytics and Machine Learning (ML) for detecting threats, anomalies, and attack patterns (security analytics).
• SecOps center (SOC) enablement, including incident triage, correlation, and response workflows.
• Integration with third-party security tools and data sources through an open architecture.

More About Stellar Cyber

Stellar Cyber focuses on enterprise and service provider SecOps through an open XDR platform (Open XDR) that aggregates and analyzes data from multiple domains, including network traffic, endpoints, cloud workloads, identities, and existing security tools. The platform is positioned for use in SecOps centers (SOCs) that require centralized visibility across heterogeneous environments and tools.

The Open XDR platform (XDR / security analytics) ingests telemetry from sensors, logs, and integrations with technologies such as firewalls, Endpoint Detection And Response (EDR) tools, cloud platforms, and identity providers. It normalizes and correlates this data into a common schema to support cross-domain detection and investigation. This approach aligns with modern security reference architectures where XDR functions alongside Security Information and Event Management (SIEM), EDR, Network Detection and Response (NDR), and Security Orchestration Automation Response (SOAR) components, and in some deployments aims to consolidate or simplify these stacks.

Stellar Cyber applies ML, behavior analytics, and rule-based correlation (security analytics) to identify threats such as lateral movement, command and control, data exfiltration, and account compromise. The platform presents detections as correlated incidents rather than individual alerts, which is designed to reduce alert volume and support incident triage. Automated and guided response workflows integrate with existing security controls, enabling actions such as blocking, quarantining, or policy updates through connected tools.

The platform’s open architecture emphasizes integrations with a range of third-party security and IT products (integrations / security ecosystem). This includes support for ingesting logs and telemetry via standard protocols such as Syslog, APIs, and cloud-native data services. The Open XDR model is designed to avoid vendor lock-in by allowing organizations to retain existing controls while adding centralized analytics and response.

In enterprise and institutional environments, Stellar Cyber is used to support SOC teams, managed security service providers (MSSPs), and Managed Detection and Response (MDR) providers. It targets use cases such as threat hunting, compliance-aligned monitoring, and incident response across hybrid and multi-cloud infrastructures. Within a directory or marketplace taxonomy, Stellar Cyber is categorized under Open XDR platforms (XDR), security analytics and threat detection (security analytics), and SOC operations and orchestration (security operations).
