Detection built for the mission network.
Commercial XDR was built for enterprise IT and the vendor’s cloud. NetDefense was built for the agencies and armed forces who can’t send their telemetry off-network. Here is how they compare.
The commercial cloud isn’t an option for everyone.
The leading XDR platforms are excellent at what they were built for: protecting commercial enterprises from a shared, vendor-operated cloud. For a defense force or an intelligence agency, that architecture is often a non-starter — the telemetry can’t leave the network, and the mission can’t depend on a multi-tenant SaaS.
NetDefense brings signals-intelligence-grade detection to networks that must stay sovereign — deployable air-gapped, with your data on your infrastructure, and network visibility built in rather than bolted on.
NetDefense vs. commercial XDR & legacy SIEM
| NetDefense (S32) | Commercial XDR / legacy SIEM | |
|---|---|---|
| Detection basis | SIGINT-powered — signals-intelligence tradecraft applied to network defense. | Signature, log-correlation, and commercial-telemetry models. |
| Deployment | Sovereign — managed, on-premise, or fully air-gapped for classified networks. | Vendor-cloud first; on-premise often limited or deprecated. |
| Data residency | Your data stays on infrastructure you control. | Telemetry flows to the vendor’s multi-tenant cloud. |
| Visibility | Network-wide, built to see what endpoint-centric tooling misses. | Often endpoint-centric, with network context bolted on. |
| Built for | Agencies and armed forces — mission networks, not commercial IT. | Commercial enterprise IT first; government as a vertical. |
| Lock-in | Open deployment, your data, your infrastructure. | Dependency on the vendor’s cloud, agents, and licensing. |
Comparisons reflect the commercial-cloud XDR and legacy SIEM models and product positioning as of 2026. S32 does not restate any competitor’s own performance claims.
Why defenders choose NetDefense
Signals-intelligence lineage
NetDefense applies SIGINT tradecraft to defense — the same discipline used to find adversaries on the wire, turned inward to protect the networks that can’t go down.
Sovereign, including air-gapped
Run it where the mission lives: managed, on-premise, or sealed for disconnected and classified environments. No telemetry leaving for a vendor cloud.
One engine, total visibility
S32 NetSentinel, NetPatriot, and NetGuardian give network-wide detection — including space-based collection — under one detection engine and one audit trail.
Total visibility, on your terms.
See how NetDefense detects what endpoint-centric, cloud-bound tooling misses — and how it fits the network you defend today.
