Owl OPDS-100 vs Sphyrna Security NGXS: 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

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.
