Stellar Cyber: Advancing Network Detection and Response Through AI-Driven Security Operations

The Network Detection and Response (NDR) market is becoming increasingly important as organizations increasingly important as organizations manage distributed IT, cloud, and operational technology environments that generate large volumes of network telemetry. NDR solutions provide visibility into network behavior and help security teams identify suspicious activity, lateral movement, command-and-control communication, and other indicators that may not be visible through endpoint or log-based security tools alone.

Within this environment, Stellar Cyber provides NDR as part of its broader security operations platform. Its NDR capability combines deep packet inspection, network telemetry collection, AI-powered detection and correlation, threat intelligence enrichment, and automated response. Stellar Cyber also positions its NDR across IT and OT environments, allowing organizations to monitor network activity across data centers, cloud workloads, and industrial environments.

360Quadrants, powered by MarketsandMarkets^TM, evaluated key players in their ‘Network Detection and Response (NDR) Key Companies Assessment Report, 2025’. The evaluation covered over 100 companies, with the top 25 categorized and recognized as quadrant leaders. Factors such as revenue, geographic presence, growth strategies, investments, demand channels, and sales strategies were analyzed to determine each company’s position in the quadrant.

The main criteria for assessing product footprint included Offering (Solutions, Services), Network Environment (Enterprise IT Networks, Cloud Networks, Industrial/OT Networks), Organization Size (Large Enterprises, SMES), Vertical (BFSI, Government, Healthcare & Life Sciences, Aerospace & Defense, Manufacturing, IT & ITeS, Retail & E-commerce, Energy & Utilities, Telecommunications, Transportation & Logistics, Media & Entertainment, and  Other Verticals).

As organizations operate across distributed networks, cloud environments, and operational technology infrastructure, security teams face increasing complexity in identifying threats across network traffic and connected systems. Traditional security approaches can leave gaps in visibility, particularly for lateral movement, east-west traffic, and activity involving assets without endpoint agents. This is driving adoption of NDR solutions that provide deep network visibility, analyze network behavior, correlate security signals, and support faster threat investigation and response.

That's where Stellar Cyber comes in. As a Progressive Company in the NDR market, Stellar Cyber enables organizations to gain deep network visibility through Deep Packet Inspection and Interflow™, while using AI-powered detection and correlation to identify threats across IT and OT environments. Its platform combines network telemetry with threat intelligence and other security data to support lateral movement detection, automated threat hunting, contextual investigation, and automated or analyst-guided response.

Stellar Cyber's strategic approach can be inferred from the following fundamental pillars:

• AI-Powered Network Detection and Response

Stellar Cyber combines AI-powered detections and correlations with NDR capabilities to identify threats across network environments. Its NDR sensors incorporate Machine Learning Intrusion Detection System (ML-IDS) capabilities, while the platform applies AI to accelerate detection and analysis.

• Deep Network Telemetry and Interflow™

Stellar Cyber uses Deep Packet Inspection (DPI) to extract Layer 2–7 metadata and files from network packets. Interflow™ then normalizes and enriches this telemetry, creating an actionable data model that supports analysis and cross-source correlation.

• IT, OT, and Cloud Network Visibility

Stellar Cyber provides network visibility across physical, virtual, cloud, and industrial environments. Its NDR architecture uses distributed sensors to collect packet and flow telemetry across network segments, supporting visibility into IT and OT environments.

• Automated Threat Hunting

Stellar Cyber provides automated threat hunting through pre-built and user-defined playbooks that search for specific behaviors across security data. These hunts can generate alerts and map findings to the XDR Kill Chain and MITRE ATT&CK techniques.

• Cross-Source Correlation and Contextual Investigation

Stellar Cyber correlates network events with activity from endpoints, servers, and users to establish the broader scope of a threat. Interflow™ further enriches telemetry with information such as threat intelligence, geolocation, host, and user context to support investigation.

• Automated Network-Level Response

Stellar Cyber connects NDR detections with automated and analyst-guided response capabilities. Its platform can block traffic, contain hosts, disable users, and trigger customized response actions through integrations with technologies such as firewalls, EDR, NAC, and SOAR.

Final Thoughts

Stellar Cyber has established a differentiated position in the NDR market through its combination of deep network telemetry, AI-powered detection, threat correlation, and automated response. Its positioning as a Progressive Company in the 360Quadrants assessment reflects its product footprint and market position within the evaluated NDR landscape. Stellar Cyber's NDR provides visibility across IT, OT, cloud, and remote environments, while its sensors combine Deep Packet Inspection, ML-IDS, and malware sandboxing to identify network-based threats and suspicious activity.

Stellar Cyber's approach also incorporates Interflow™, automated correlation, threat intelligence, and automated threat hunting to turn network telemetry into contextualized security information. Interflow normalizes and enriches network data, while the platform correlates network events with endpoint, server, user, and other security signals to identify the broader scope of threats. These capabilities complement Stellar Cyber's NDR offering by supporting lateral-movement detection, investigation, threat hunting, and automated or analyst-guided response across IT and OT environments.
