Trellix NDR Strengthens OT-IT Security Convergence

Why It Matters

By consolidating OT and IT security, organizations can stop lateral attacks earlier, protecting critical infrastructure and meeting tightening regulatory demands. Faster, automated response translates into lower breach costs and improved operational resilience.

Key Takeaways

• Unified OT‑IT visibility via Nozomi integration
• AI-driven detections across MITRE ATT&CK stages
• Hyperautomation shortens detection‑to‑response cycle
• 82% CISOs warn of OT‑IT security gaps
• Automated triage cuts analyst workload significantly

Pulse Analysis

The convergence of operational technology (OT) and information technology (IT) has become a focal point for cyber‑risk managers as attackers exploit the blind spots at the network boundary. Traditional security tools often lack the telemetry needed to monitor industrial control systems, leaving a gap that threat actors can leverage for lateral movement. Industry surveys reveal that more than four‑fifths of CISOs consider this divide a top‑priority risk, prompting vendors to develop solutions that provide end‑to‑end visibility across both domains.

Trellix NDR addresses this challenge with a multi‑layered approach. Its certified integration with Nozomi Networks pulls AI‑generated alerts and asset data directly into the NDR console, eliminating the need for agents in sensitive OT environments. The platform’s behavioral analytics map East‑West and North‑South traffic against the MITRE ATT&CK framework, delivering high‑fidelity alerts that prioritize real threats. Meanwhile, the Hyperautomation engine offers a drag‑and‑drop workflow builder, enabling security teams to orchestrate containment actions—such as isolating compromised segments or throttling anomalous DNS queries—without writing code, thereby compressing the detection‑to‑response timeline.

For enterprises, the practical benefits extend beyond threat mitigation. Unified OT‑IT monitoring simplifies compliance reporting for standards like IEC 62443 and NERC CIP, while automated triage reduces analyst fatigue and operational costs. As more critical infrastructure providers adopt zero‑trust architectures, solutions that seamlessly fuse OT and IT data will likely become a market differentiator. Trellix’s latest NDR enhancements position it to capture a growing slice of the cybersecurity spend aimed at protecting the industrial backbone of the global economy.
