NetDefense
Extended detection and response, powered by signals intelligence — for the agencies and armed forces who can’t afford to be caught off guard.
One detection engine. Total network visibility.
NetDefense is S32’s SIGINT-powered XDR platform for national-security network defense. At its core is the S32 NetSentinel detection engine — deep, real-time visibility across every packet, device, and flow — extended globally by NetPatriot and NetGuardian.
It composes into a single picture or deploys tier by tier, scaling from one network to globally distributed infrastructure without losing fidelity.
Inside NetDefense
S32 NetSentinel — the core detection engine
Real-time visibility & ML detection
The detection engine at the heart of NetDefense: real-time network visibility, deep packet inspection, and asset discovery, with machine-learning detection of malware, ransomware, insider threats, and zero-day exploits — plus continuous vulnerability management, automated patch and configuration analysis, compliance, and live threat-intelligence enrichment.
S32 NetPatriot
Intelligence-driven network defense
Extends the NetSentinel engine globally with enhanced interception and collection — deep visibility, control, and threat detection across your entire network infrastructure.
S32 NetGuardian
Space-based collection
Advanced interception and collection tailored for space-based operations and national-scale coverage.
From packet to response.
Collection & visibility
Deep packet inspection, asset discovery, and flow capture across on-premise, cloud, and space-based infrastructure.
NetSentinel engine
ML detection of malware, ransomware, insider threats, and zero-days — enriched with live threat intelligence.
One composed picture
NetPatriot and NetGuardian extend the engine globally, correlating every tier into a single operating picture.
SOC action
Prioritized detections, vulnerability posture, and compliance state — routed to your team to act before an intrusion spreads.
The NetDefense loop, from raw traffic to operator action — a single picture, or independent tiers deployed to the mission.

Frequently asked
What is NetSentinel’s role in NetDefense?
NetSentinel is the core detection engine inside NetDefense — real-time visibility, deep packet inspection, asset discovery, and ML detection — not a separate product. NetPatriot and NetGuardian extend it globally.
How is NetDefense deployed?
Across on-premise, cloud, and hybrid environments — from a single network up to globally distributed infrastructure, including space-based collection.
How quickly do teams see results?
Most clients report improved threat visibility within 60 days, with a measurable reduction in mean-time-to-detect.
