Detect. Correlate. Defeat. Sophisticated threats demand deeper visibility. Stellar Cyber unifies advanced SIEM with OT-aware NDR and multi-layered AI to detect what others miss—across endpoints, networks, and agentless systems.

In complex enterprise or OT environments, this is rarely the case: ## No Logs from Critical Assets Many critical assets (OT, legacy, unmanaged) **don’t generate logs** or lack agents. ## SIEM Blind to Encrypted Traffic SIEMs struggle with **encrypted east-west traffic** or lateral movement that’s invisible to traditional log sources. ## High Log Costs Limit Visibility Excessive log ingestion can drive **unsustainable storage and licensing costs,**limiting visibility in practice. The result: **undetected threats operating inside the network,** often for weeks or months.

It focuses on endpoint telemetry, and: ### Deployment Limitations Can’t be deployed on**proprietary OT systems,** network devices, or unmanaged endpoints. ### Limited Insights Offers limited insight into **pre-attack reconnaissance,** privilege escalation, or lateral movement across VLANs. ### No Network Intrusion Visibility Detects post-compromise activity, **not initial network-based intrusions**or command-and-control (C2) behavior. #### In isolation, SIEM + EDR can’t reconstruct the full attack narrative—or stop threats before damage is done. ## Deep Network Visibility with OT-Aware NDR Stellar Cyber’s integrated **NDR**analyzes Layer 2–7 traffic across both **IT and OT domains**, providing **agentless, real-time visibility** into network behavior. With **deep packet inspection (DPI)**, protocol decoding, and Multi-Layer AI, our NDR detects: ## Lateral Movement via SMB & RDP **Lateral movement**using SMB, RDP, and custom protocols ## Command-and-Control Detection **Command-and-control communication**, even using encrypted or covert channels ## Data Exfiltration Detection **Exfiltration of sensitive data,** regardless of endpoint involvement ## ICS/SCADA Protocol Misuse **ICS/SCADA protocol misuse,** such as Modbus or DNP3 commands outside of baselines It’s also **OT-aware**, with built-in support for industrial protocols, asset profiling, and segmentation breach detection. ## Multi-Layered AI Powers Detection, Correlation & Triage #### Unlike traditional SIEMs or standalone NDR tools, Stellar Cyber’s platform embeds Multi-Layer AI at every level ### Detection AI ### Detection AI Machine learning models identify anomalies and behavior-based deviations, even in zero-day scenarios. ### Correlation AI ### Correlation AI Automatically links events across SIEM, NDR, EDR, and other data sources—creating **context-rich incident stories.** ### Response AI ### Response AI Prioritizes alerts, auto-triages low-confidence detections, and integrates with SOAR tools or native playbooks for fast action. #### This AI foundation means ### Quick Threat Detection ### Quick Threat Detection **Faster MTTD (Mean Time to Detect)** via real-time traffic inspection ### Less Alert Fatigue ### Less Alert Fatigue **Reduced analyst fatigue** from alert overload ### High-Fidelity Detections ### High-Fidelity Detections **Higher fidelity detections**without excessive tuning ## Unified Platform = Simpler, Smarter SecOps Stellar Cyber isn’t just integrating SIEM and NDR—we’ve unified them within a single Open XDR platform, streamlining deployment, licensing, and operations: **Single pane of glass**for detection, investigation, and response **Multi-tenant ready** for MSSPs and large-scale enterprise use **Data normalization and enrichment** at ingestion—no more stitching logs and flows manually **Built-in connectors** for firewalls, OT gateways, cloud logs, and threat intelligence feeds ## Stop Lateral Movement. Secure OT. Reduce Risk. #### In an age of ransomware, supply chain breaches, and nation-state threats, visibility must extend beyond logs and endpoints. Only **SIEM + OT-aware NDR,**unified with AI-driven correlation, delivers the depth and breadth needed to Stop stealthy attacks earlier in the kill chain Provide asset-agnostic detection across IT and OT Meet compliance and risk quantification demands ## Ready to go beyond SIEM + EDR?
