Sphyrna NGXS UGW-100 is a commercial operational technology network segmentation tool by Sphyrna Security. Compare features, ratings, integrations, and community reviews side by side to find the best operational technology network segmentation fit for your security stack.
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 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.
Enterprise and mid-market security teams protecting sensitive OT networks from east-west lateral movement need the Sphyrna NGXS UGW-100 because hardware-enforced unidirectional gateways are the only architecture that actually stops data exfiltration at the physics level, not the policy level. EAL 4+ Common Criteria and TEMPEST Zone 1 certifications mean this box works in high-assurance environments where software-only controls fail compliance audits. Skip this if your priority is network visibility or threat hunting; the UGW-100 is a one-way valve, not a sensor, and it won't help you detect what's moving across the boundary.
