Armis Centrix™ Network Segmentation vs Zscaler IoT and OT Security: 2026 Comparison

Armis Centrix™ Network Segmentation

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.

Zscaler IoT and OT Security

Enterprise security teams managing sprawling IoT and OT networks will see immediate value in Zscaler IoT and OT Security's agentless device discovery and segmentation, which bypasses the usual firmware compatibility headaches that plague traditional firewall-based approaches. The platform's zero trust segmentation without agents covers both ID.AM asset management and PR.AA access control, two areas where most OT shops have critical blind spots. Skip this if your environment is heavily air-gapped or your vendors won't tolerate cloud-based visibility; the cloud deployment model is a feature for most, a non-starter for some.
