Armis Centrix™ Network Segmentation vs Sphyrna Security NGXS Passive Data Diode: 2026 Comparison

Armis Centrix™ Network Segmentation

Healthcare and medical device-heavy enterprises need Armis Centrix™ Network Segmentation because it discovers and maps IoMT communication paths that generic segmentation tools miss, then enforces policy without requiring manual device reconfiguration. The platform covers NIST asset management and continuous monitoring across its core workflow, and automated quarantine of compromised devices actually closes the gap between detection and containment that most segmentation solutions leave open. Skip this if your environment is mostly standard IT infrastructure with few connected medical devices; the value proposition narrows significantly outside healthcare and life sciences.

Sphyrna Security NGXS Passive Data Diode

Enterprise and mid-market OT teams managing critical infrastructure with zero-trust segmentation requirements should pick the NGXS Passive Data Diode for its truly unidirectional optical isolation, which eliminates backhaul attack paths that active devices leave open. The 10Gbps throughput over passive fiber optic transmission means you're not introducing a networked chokepoint that needs patching, and that aligns directly with NIST PR.IR resilience architecture by removing a potential single point of failure. This isn't for buyers seeking software-defined segmentation or cloud-native OT connectivity; you're committing to hardware-based, physics-enforced isolation in fixed network topologies.
