Enhancing OT Security with Deep Network Observability Aviz and Nozomi Networks
March 31, 2026
Deep Network Observability
Industrial and critical infrastructure environments are undergoing rapid digital transformation. As IT, OT, and IoT systems become increasingly interconnected, organizations gain efficiency and visibility but also introduce new cybersecurity risks.
Platforms like Nozomi Networks provide advanced OT visibility, threat detection, and operational insight. However, their effectiveness depends heavily on one critical factor: the quality and completeness of the network traffic they analyze.
This is where Aviz Networks Deep Network Observability (DNO) plays a foundational role.
The Challenge: OT Security Requires More Than Just Visibility
Unlike traditional IT environments, industrial networks are highly distributed, latency-sensitive, and operationally critical. Ensuring security without disrupting operations requires precise, real-time visibility.
Organizations commonly face challenges such as:
- Fragmented traffic across plants, substations, and cloud-connected environments
- Excessive and redundant traffic is overwhelming monitoring tools
- Blind spots in East–West and process-level communications
- Limited real-time visibility into industrial assets
- Increased operational risk due to undetected anomalies
Without an intelligent way to capture, filter, and optimize traffic, even the most advanced OT security platforms struggle to deliver accurate insights.
The Solution: Deep Observability for OT and IoT Security
The joint solution from Aviz Networks and Nozomi Networks introduces a deep network observability layer that ensures only relevant, high-quality, and enriched traffic reaches Nozomi analytics.
At the core, Aviz DNO acts as a traffic intelligence layer, sitting between network traffic sources and Nozomi sensors.
This architecture enables:
- Scalable visibility across IT, OT, and IoT environments
- Optimized traffic delivery for improved detection accuracy
- Real-time asset discovery and monitoring
- Faster detection of threats and operational anomalies
How It Works
The solution follows a streamlined traffic intelligence pipeline:
Traffic Acquisition
Network traffic is collected from TAPs and SPANs across industrial and enterprise environments.
Traffic Aggregation and Filtering (Aviz Packet Broker)
Traffic is aggregated, filtered, and load-balanced to eliminate noise and improve efficiency.
Traffic Optimization and Enrichment (Aviz Service Node)
Packets are deduplicated and enriched with application and protocol context.
Optimized Delivery to Nozomi Networks
Clean, high-fidelity traffic is delivered to Nozomi sensors for analysis.
Threat Detection and Operational Insight
Nozomi analyzes traffic to detect threats, monitor assets, and provide real-time visibility.
Why This Matters
By combining Aviz traffic intelligence with Nozomi OT security analytics, organizations gain a more accurate and actionable view of their industrial environments.
Key benefits include:
- Improved OT and IoT asset visibility
- Higher detection accuracy with reduced noise
- Faster identification of cyber threats and anomalies
- Enhanced operational resilience and uptime
- Lower infrastructure and monitoring costs
Conclusion
As industrial environments continue to evolve, visibility alone is not enough. Organizations need intelligent, optimized, and context-rich network telemetry to drive accurate security and operational outcomes.
The joint solution from Aviz Networks and Nozomi Networks delivers exactly that combining deep network observability with advanced OT threat detection to help organizations reduce risk, improve visibility, and strengthen operational resilience.

1. Why is OT and critical infrastructure security becoming more complex?
Industrial environments are rapidly digitizing, with IT, OT, and IoT systems becoming interconnected. While this improves efficiency and visibility, it also expands the attack surface and introduces new cybersecurity risks.
2. Why is network traffic quality critical for OT security platforms?
OT security platforms rely on network traffic to identify assets, detect threats, and monitor operations. If the traffic is incomplete, noisy, or fragmented, detection accuracy and visibility are significantly reduced.
3. How does Nozomi Networks provide OT visibility and threat detection?
Nozomi Networks analyzes network traffic to deliver deep OT and IoT asset visibility, threat detection, anomaly identification, and operational insights without disrupting industrial operations.
4. What are the main challenges in securing industrial networks?
Industrial networks face fragmented traffic across plants and substations, excessive redundant data, blind spots in East–West communications, limited real-time visibility, and high operational risk if anomalies go undetected.
5. Why is traditional network monitoring insufficient for OT environments?
OT environments are latency-sensitive and operationally critical. Traditional monitoring tools often overwhelm security platforms with noise and lack the intelligence needed to safely analyze industrial traffic in real time.
6. What role does Aviz Networks play in OT security?
Aviz Networks provides Deep Network Observability (DNO), acting as an intelligent traffic layer that captures, filters, optimizes, and enriches network traffic before analysis.
7. How does Deep Network Observability improve detection accuracy?
By removing redundant traffic, eliminating duplicates, and enriching packets with protocol and application context, DNO ensures that OT security tools receive clean, high-fidelity traffic for more accurate analysis.
8. How does the Aviz and Nozomi joint solution work?
Aviz collects and optimizes traffic from TAPs and SPANs, enriches it with context, and delivers only relevant data to Nozomi sensors, enabling faster threat detection and real-time asset monitoring.
9. What benefits do industrial organizations gain from the Aviz–Nozomi joint solution?
Organizations gain improved OT and IoT asset visibility, higher detection accuracy, faster threat identification, improved operational resilience, reduced downtime, and lower monitoring and infrastructure costs.
10. What is the key takeaway for industrial and critical infrastructure security?
Effective OT security requires more than visibility. Intelligent, optimized, and context-rich network telemetry is essential to reduce risk, improve detection, and maintain operational continuity in modern industrial environments.
