Beyond SIEM + EDR
See More, Stop More with
OT-Aware NDR + AI-driven SIEM
Expose. 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.
Triage Demo
SIEM Alone Leaves You Blind in Critical Areas
A SIEM is designed to aggregate, normalize, and correlate logs from across your environment—but only when those logs are available, structured, and high fidelity. In complex enterprise or OT environments, this is rarely the case:
No Logs from Critical Assets
SIEM Blind to Encrypted Traffic
High Log Costs Limit Visibility
The result: undetected threats operating inside the network, often for weeks or months.
Why EDR Falls Short in Hybrid and OT Environments
EDR is essential—but not sufficient. 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
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
Multi-Layered AI Powers Detection, Correlation & Triage

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.
Stop stealthy attacks earlier in the kill chain
Provide asset-agnostic detection across IT and OT
Meet compliance and risk quantification demands
