Why can't I just use standard IT security tools for my OT network?

IT tools are often too disruptive (like agents) and lack deep understanding of industrial protocols and environments, leading to false positives or missed threats.

How does Nozomi Networks monitor OT networks without disrupting operations?

It primarily uses passive network monitoring via a dedicated sensor (Guardian) that mirrors traffic via a SPAN port or network tap, analyzing data without sending packets onto the OT network.

What is the difference between threat detection and anomaly detection?

Threat detection uses signatures to find known attacks, while anomaly detection uses AI/ML to baseline normal behavior and flag deviations, which is crucial for finding zero-days or insider threats in OT.

How does the platform handle IT/OT convergence?

It provides unified visibility across both IT and OT networks, helping identify risky connections and enforce security policies where these converged environments meet.

Building Cyber Resilient OT Systems — IEC 62443 in Practice

As cyber threats to operational technology rise, organisations across the Asia-Pacific are under growing pressure to strengthen OT security. IEC 62443 — the internationally recognised standard for securing industrial automation and control systems (IACS) — has become the global benchmark for managing industrial cybersecurity risk. Regulators across the region, including Australia’s critical infrastructure legislation, are increasingly adopting or aligning with IEC 62443. For OT security teams, applying these standards is now essential for both compliance and resilience. In this webinar, experts from Nozomi Networks and ABB will share practical guidance on IEC 62443 and how to overcome the challenges of implementation. Watch now to: - Gain a practical understanding of IEC 62443 and why it matters. - Learn how to operationalise IEC 62443 in your region. - Hear real-world success stories: how enterprises are applying segmentation, defense-in-depth, and secure lifecycle strategies.
