Network Sensor
Complete Internal Network Visibility, Threat Detection, and Automated Response
ThreatDefence's Network Detection and Response (NDR) module provides deep, continuous monitoring of all internal network traffic, delivering real-time threat detection and automated response capabilities. By analyzing east-west and north-south traffic patterns, our NDR identifies malicious activity that other security tools miss—from lateral movement and data exfiltration to zero-day attacks and compromised devices—giving you complete visibility into what's happening inside your network.
How It Works: Continuous Network Protection
Passive Traffic Analysis: Our sensors passively monitor all network traffic through SPAN ports or network taps, providing full visibility without impacting network performance or requiring agent installation.
Behavioral Analytics: Advanced machine learning establishes normal behavior baselines for every device and user on your network, immediately flagging anomalies and suspicious patterns that indicate potential threats.
Protocol Analysis: Deep packet inspection decodes and analyzes dozens of common protocols (HTTP, DNS, SSL/TLS, RDP, SMB) to identify malicious activity hidden within legitimate traffic.
Automated Response: Integrated SOAR playbooks enable immediate containment actions—such as blocking malicious IPs, isolating compromised devices, or disabling suspicious user accounts—directly from alerts.
Key Benefits
✅ Agentless Deployment Gain immediate visibility without installing software on endpoints. Our sensors connect seamlessly to existing network infrastructure.
✅ Complete Internal Visibility Monitor all network traffic, including unmanaged IoT devices, operational technology, and shadow IT that other security tools can't see.
✅ Advanced Threat Detection Identify sophisticated attacks that bypass traditional security tools, including insider threats, lateral movement, and data exfiltration.
✅ Encrypted Traffic Analysis Gain insights into encrypted communications without decryption, identifying malicious patterns in SSL/TLS traffic through certificate and behavioral analysis.
What It Detects
Lateral movement and unauthorized access attempts between internal systems
Data exfiltration and unusual data transfers to external destinations
Command and control (C2) communications and beaconing activity
Ransomware and malware propagation across the network
Suspicious protocol usage and policy violations
Compromised devices and insider threat activity
Use Cases
Ransomware Containment: Detect and automatically contain ransomware spread by isolating infected endpoints before encryption begins.
Insider Threat Detection: Identify unauthorized data access and exfiltration attempts by malicious insiders or compromised accounts.
Incident Investigation: Conduct comprehensive forensic analysis using full packet capture and flow data to understand attack scope and impact.
IoT and OT Security: Monitor and secure unmanaged devices, industrial control systems, and operational technology that can't run traditional security agents.
Compliance Auditing: Generate detailed network activity reports for regulatory requirements like PCI DSS, HIPAA, and NIST frameworks.
Why It Matters
Traditional security tools focus on perimeter defense and known threats, leaving your internal network vulnerable to sophisticated attacks that have bypassed initial defenses. ThreatDefence NDR provides the critical internal visibility needed to detect, investigate, and respond to threats operating inside your environment. By combining behavioral analytics, automated response, and comprehensive network monitoring, we ensure you can identify and stop attacks that would otherwise remain undetected for months.
See everything happening inside your network—and stop threats before they cause damage.
