Aviz Networks and Nozomi Networks detail OT traffic observability pipeline

Aviz Networks and Nozomi Networks describe a joint approach to Operational technology (OT) and Internet of Things (IoT) security that emphasizes traffic quality by routing enriched, filtered network telemetry into Nozomi sensors. For enterprise IT and OT leaders, the update focuses on reducing noise and improving asset and threat visibility in complex industrial networks.

Research Overview

The blog frames industrial and critical infrastructure security as a challenge that grows as IT, OT, and IoT systems connect across distributed environments. It also argues that OT security platforms depend on the quality and completeness of the network traffic they analyze.

It presents Deep Network Observability (DNO) from Aviz Networks as a foundation for improving the usefulness of telemetry delivered to OT threat analytics.

Key Findings

The authors state that industrial networks are highly distributed and latency-sensitive, requiring precise, real-time visibility without disrupting operations. They cite problems including fragmented traffic across on-premises (on-prem) and cloud-connected segments, monitoring overload from excessive or redundant traffic, and blind spots in East–West and process-level communications.

The blog adds that organizations face limited real-time visibility into industrial assets, along with increased operational risk from undetected anomalies.

Technical Breakdown

The joint solution is described as a deep network observability layer between traffic sources and Nozomi sensors. Aviz DNO is positioned as a traffic intelligence layer that delivers scalable visibility and optimized traffic for improved detection accuracy, including real-time asset discovery and monitoring.

The traffic pipeline is outlined as traffic acquisition from TAPs and SPANs, aggregation and filtering via the Aviz Packet Broker with deduplication and load balancing, enrichment via the Aviz Service Node with application and protocol context, and optimized delivery of clean, high-fidelity traffic to Nozomi sensors for analysis.

Operational Impact

The blog says combining Aviz traffic intelligence with Nozomi OT security analytics provides a more accurate view of industrial environments. It lists benefits tied to improved OT and IoT asset visibility, higher detection accuracy with reduced noise, and faster identification of cyber threats and anomalies.

Additional outcomes cited include enhanced operational resilience and uptime and lower infrastructure and monitoring costs.

Overall, the blog centers on the premise that industrial security outcomes depend on enriched and noise-reduced telemetry delivered to OT analytics. Blog Signals brief is a fact-based summary of the vendor blog.
