Armis Centrix™ vs Nozomi Networks Nozomi Guardian: Side-by-Side Comparison (2026)

Short answer

Mid-market and enterprise security teams managing sprawling IoT, OT, and medical device environments will get the most from Armis Centrix™ because its agentless discovery actually works across protocols most tools ignore. The platform covers all four NIST Identify and Detect functions, with particular strength in continuous asset monitoring and vulnerability prioritization that cuts through noise in environments with thousands of unmanaged devices. Not the pick if you need deep forensic analysis or incident response automation; Centrix prioritizes visibility and risk ranking over post-breach investigation. Mid-market and enterprise OT teams that lack visibility into their operational networks will benefit most from Nozomi Guardian's passive monitoring approach, which discovers and inventories assets without disrupting production systems. The platform covers all four NIST ID and DE functions, but prioritizes asset discovery and continuous anomaly detection over incident response capabilities; if your team needs playbook-guided remediation built into the tool itself rather than handed off to ticketing systems, you'll do more manual work than vendors suggest. Skip this if you're running primarily IT infrastructure without significant OT/IoT footprint, or if your brownfield OT environment has devices that don't speak standard protocols Nozomi supports.
