Armis Centrix™ IT/OT Security is a commercial operational technology network segmentation tool by Armis. 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 teams running converged IT/OT environments will get the most from Armis Centrix™ IT/OT Security because it actually maps segmentation policy to device reality instead of just visualizing the network topology. The platform covers all five NERC CIP compliance domains and generates ACLs directly from segmentation rules, which matters when you're auditing brownfield industrial sites where manual segmentation documentation is nonexistent. Skip this if your OT environment is air-gapped or if you need deep forensic visibility into lateral movement after breach; Centrix prioritizes prevention and continuous conformance monitoring over post-incident investigation.
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.
