Owl OPDS-100 vs Sphyrna Security NGXS Passive Data Diode: Side-by-Side Comparison (2026)

Owl OPDS-100

Enterprise and mid-market security teams protecting critical infrastructure from lateral movement will find the Owl OPDS-100's hardware-enforced one-way data transfer uniquely valuable when network segmentation must survive active compromise. The 1U form factor and physical data diode design deliver the PR.IR control maturity that pure software segmentation cannot guarantee, especially in OT environments where the cost of failure justifies appliance-class hardware. Pass if your throughput demands exceed low-to-moderate rates or if you need east-west microsegmentation across hundreds of internal pathways; this tool is built for perimeter hardening and critical asset protection, not general-purpose network slicing.

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.
