Cervello Platform vs Nozomi Networks Nozomi Guardian: Side-by-Side Comparison (2026)

Cervello Platform

Mid-market and enterprise rail operators need asset visibility without disrupting critical signaling and rolling stock systems, and Cervello Platform delivers that through purely passive network monitoring across OT/ICS environments. It maps your entire rail topology and detects threats without requiring agents or service interruption, which matters when you're running 24/7 operations where downtime costs millions. The platform prioritizes detection and asset intelligence over incident response playbooks; if your team needs deep forensic capabilities or automated remediation workflows, you'll be patching those gaps with a SIEM integration rather than getting them native.

Nozomi Networks Nozomi Guardian

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.
