Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Enterprise and mid-market teams protecting classified or highly sensitive data across air-gapped networks will find Sphyrna Security NGXS valuable for its hardware-enforced unidirectional transfer, which operates independently of operating system vulnerabilities. Common Criteria EAL 4+ certification and ITSG-33 compliance give you the compliance posture required in government and defense environments without relying on software-layer security. Skip this if your priority is cross-domain data sharing with minimal operational friction; the filtering diode and policy enforcement model demand careful network architecture planning and aren't designed for high-frequency, low-friction data movement between connected systems.
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.
