Zscaler IoT and OT Security vs Armis Centrix™ IT/OT Security: 2026 Comparison

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.

Armis Centrix™ IT/OT Security

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.
