Armis Centrix™ IT/OT Security vs Sphyrna HFD Data Diode: 2026 Comparison

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.

Sphyrna HFD Data Diode

Enterprise and mid-market OT security teams protecting critical infrastructure from east-west lateral movement will get the most from Sphyrna HFD Data Diode because it enforces unidirectional data flow at wire speed with hardware-level assurance that no firmware or software compromise can bypass. The FPGA architecture with separate ingress and egress quads plus encrypted, signed rulesets mean you can filter at layers 2-4 and decrypt traffic for inspection without creating a single point of trust failure on the network path itself. Skip this if your environment is predominantly IT-focused or you need bidirectional segmentation; data diodes are inherently one-way tools and there's no workaround for that constraint.
