Armis Centrix™ Network Segmentation is a commercial operational technology network segmentation tool by Armis. Nexor Data Diode is a commercial operational technology network segmentation tool by nexor. 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:
Healthcare and medical device-heavy enterprises need Armis Centrix™ Network Segmentation because it discovers and maps IoMT communication paths that generic segmentation tools miss, then enforces policy without requiring manual device reconfiguration. The platform covers NIST asset management and continuous monitoring across its core workflow, and automated quarantine of compromised devices actually closes the gap between detection and containment that most segmentation solutions leave open. Skip this if your environment is mostly standard IT infrastructure with few connected medical devices; the value proposition narrows significantly outside healthcare and life sciences.
Enterprise and mid-market operations teams protecting critical infrastructure will want Nexor Data Diode when network segmentation must survive determined adversaries; this is one of the few tools that enforces unidirectionality at the hardware level, eliminating the compromise vectors that plague IP-routed air gaps. Common Criteria EAL7+ certification and alignment with NCSC and NATO standards mean you're getting physical enforcement, not just firewall rules. Skip this if you need bidirectional communication or expect frequent configuration changes; the sealed, maintenance-free design is a strength for static security boundaries but a liability for dynamic environments.
