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
