CST VerdictShort answer
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. Mid-market and enterprise security teams managing heterogeneous device environments will get the most from Genian NAC because its Layer 2 enforcement catches rogue devices and anomalies that IP-layer tools miss, enforcing access before devices ever reach your network. The built-in RADIUS and DHCP servers eliminate dependency on external infrastructure, and the platform delivers strong coverage across NIST ID.AM, PR.AA, and DE.CM functions simultaneously. Skip this if you need cloud-native segmentation or assume your IT team has bandwidth to manage on-premises appliances; Genian requires hands-on operational ownership and doesn't integrate deeply with modern cloud identity layers.
