Trellix Network Security Appliance

Signatureless threat detection that blocks advanced, zero-day network attacks

Comprehensive network security protection

Stop the advanced threats traditional firewalls miss. Trellix Network Security Appliance (NX) isolates and detonates evasive, zero-day malware in a secure sandbox before it strikes. By converting complex network anomalies into real-time, actionable alerts, it prevents lateral movement, protects critical data, and strengthens your cyber resilience.

Why Trellix Network Security?

Signatureless Dynamic Sandboxing (The IVX Engine)

The IVX engine uses dynamic behavioral analysis instead of traditional signature matching.

Multi-Stage Kill Chain & Lateral Movement Detection

Advanced behavioral analytics map the kill chain, including internal "East-West" traffic.

Inline Encrypted Traffic Analysis (ETA)

Find malicious activity hiding in encrypted traffic while minimizing latency and privacy concerns.

High-Fidelity Alerting & Unified SOC Workflows

Filter out network "noise" to focus on real malicious behavior and reduce alert fatigue.

Intelligent Virtual Execution (IVX) Engine

Signature-less sandboxing intercepts suspicious files, web objects, URLs, and code directly from live network traffic and detonates them inside an isolated, multi-OS hypervisor virtual environment.

Multi-Stage Lateral Movement Detection

Many boundary appliances only watch data passing in and out of the building. Trellix NX uses advanced internal analytics rules to monitor "East-West" traffic and identify post-compromise activity.

Integrated Real-Time Inline Blocking

Trellix NX is designed to drop threats directly on the wire before they hit endpoints. When deployed inline, it uses active blocking alongside a conventional IPS (Intrusion Prevention System) engine.

MITRE ATT&CK Context Enrichment & Guided Workflows

To combat alert fatigue, Trellix NX automatically correlates detected malicious network events, prioritizes them by critical asset risk, and maps tactics directly to the MITRE ATT&CK framework.

Frequently asked questions

Trellix Network Security uses multiple advanced techniques, including the Intelligent Virtual Execution (IVX) engine, machine learning, and AI. The IVX engine performs signature-less, dynamic analysis of suspicious traffic in a safe virtual environment. Machine learning and AI engines use contextual rules to detect and block malicious activity retroactively and in real time. This multi-layered approach enables the detection of zero-day, multi-flow, and other evasive attacks that traditional defenses might miss.

Yes, Trellix Network Security includes an advanced correlation and analytics engine that detects suspicious lateral movements across your entire network. It uses over 180 rules for lateral movement detection, providing complete kill-chain visibility. Trellix Network Security also incorporates machine learning for data exfiltration detection, JA3 detection for encrypted communication, and web shell detection, mapping these to the MITRE ATT&CK framework.

Trellix Network Security integrates with several other security solutions to enhance overall protection and streamline workflows. It can be integrated with the Trellix Central Management System to correlate Network and Email Security alerts. It also works with Trellix Network Forensics for detailed packet captures and investigations. Additionally, it integrates with Trellix Endpoint Security to identify, validate, and contain compromises detected by Network Security, simplifying containment and remediation of affected endpoints.

Trellix Network Security addresses alert fatigue in several ways. It uses the IVX engine to validate alerts detected by conventional signature-matching methods, reducing false positives. The solution also employs riskware categorization to prioritize alerts by separating critical threats from less malicious activity like adware. Additionally, to improve overall efficiency, it provides concrete real-time evidence with each alert, allowing security teams to quickly assess and respond to genuine threats.
