IBM QRadar Network Insights 1920 16×2.5″ – Deep Network Visibility and Packet Inspection

The IBM QRadar Network Insights 1920 16×2.5″ appliance is purpose-built to give security operations teams full visibility into network traffic through deep packet inspection and real-time flow analysis. This powerful solution plays a critical role in uncovering hidden threats, identifying anomalous activity, and enhancing the fidelity of threat detection within the broader IBM QRadar Security Intelligence Platform.

Engineered for speed, reliability, and precision, the 1920 model is built on the Lenovo System SR650 M6 server platform. It brings enterprise-grade performance and flexibility to network security environments that demand accurate, high-speed packet capture and processing.

Key Features of IBM QRadar Network Insights 1920 16×2.5″

1. Powerful Dual-Processor Performance

The appliance is powered by two Intel Xeon Gold 6240 processors, each delivering 18 physical cores (36 total). This CPU configuration provides the computational horsepower necessary to handle complex data sets and high-volume traffic analysis, enabling deep and real-time packet inspection without performance degradation.

Whether analyzing malware communications, insider threats, or lateral movement, the IBM QRadar Network Insights 1920 16×2.5″ performs with exceptional speed and efficiency.

2. High-Speed Network Traffic Processing

The appliance is designed to handle up to 10 Gbps of sustained network throughput. This capability ensures your SOC can capture and analyze mirrored traffic in real time, detecting threats that traditional log-based monitoring may miss. The 10 GbE SFP+ ports support both data ingestion and management traffic separation, ensuring network efficiency and security.

3. Advanced Packet Capture with Napatech Technology

Central to the power of the IBM QRadar Network Insights 1920 16×2.5″ are its two Napatech capture cards, each featuring 4 capture ports. These specialized network cards are optimized for zero-packet-loss performance and are capable of capturing raw mirrored network traffic with ultra-low latency.

This packet-level visibility allows your team to:

• Detect command-and-control (C2) activity

• Reconstruct network sessions

• Analyze full payloads for malware or exploit signatures

The system is ideal for forensic investigations, threat hunting, and advanced persistent threat (APT) detection.

4. Flexible and Comprehensive Network Connectivity

The appliance includes a full range of I/O ports for flexible deployment:

• 2 x 10 GbE SFP+ ports for management

• 4 x SFP/SFP+ capture ports (via Napatech cards)

• 4 x 1 GbE Ethernet ports

• 1 x IMM (Integrated Management Module) port for remote hardware management

These options ensure seamless integration into your existing infrastructure, whether you’re using fiber or copper, and allow for robust remote system control.

5. Reliable Enterprise-Grade Storage

The IBM QRadar Network Insights 1920 16×2.5″ comes with 2 x 480 GB Enterprise SATA SSDs configured in RAID 1. This setup provides high-speed read/write performance with built-in redundancy, minimizing data loss risk during hardware failure and ensuring consistent performance for packet indexing and temporary storage.

6. Massive Memory for Data Processing Efficiency

With 256 GB of DDR4 RAM (8 x 32 GB DIMMs), this appliance can store and process vast amounts of packet metadata and session data in memory. This improves analysis speed and responsiveness, especially when handling simultaneous data streams across multiple capture ports.

The high memory capacity also ensures scalability and performance during peak traffic periods or when dealing with large-scale breach investigations.

Deployment Scenarios and Use Cases

The IBM QRadar Network Insights 1920 16×2.5″ is ideal for organizations that require advanced threat visibility at the network level. Common use cases include:

• Full packet capture for forensic analysis

• Lateral movement detection in east-west traffic

• Encrypted traffic inspection with session metadata extraction

• Detection of DNS tunneling, beaconing, and command-and-control traffic

• Enhancing detection confidence in IBM QRadar SIEM by correlating flow and packet data

By adding QRadar Network Insights to your deployment, you enhance threat detection with contextual network intelligence, not just log-based indicators.
