Armis Centrix™ IT/OT Security is a commercial operational technology network segmentation tool by Armis. Sphyrna NGXS UGW-200 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 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.
