Sphyrna NGXS UGW-200 vs Owl DiOTa: 2026 Comparison

Enterprise and mid-market security teams protecting industrial control systems or classified networks from data exfiltration need the Sphyrna NGXS UGW-200 because its hardware-enforced unidirectional gateway eliminates the attack surface that traditional firewalls leave open. NSA approval plus Common Criteria EAL 4+ certification, paired with 20Gbps maximum throughput over 25Gbps interfaces, means you're getting speed without sacrificing the cryptographic assurance that regulators actually care about. Skip this if your threat model is application-layer attacks or you need bidirectional control; unidirectional gateways are a hard architectural choice that only works when one-way data flow matches your actual use case.
