Strengthening OT Security for Global Manufacturing

A globally recognized manufacturer operating over 30 industrial plants across 12 countries approached NXFORT to enhance its Operational Technology (OT) security posture. Their rapid digitalization and legacy infrastructure exposed critical production assets to evolving cyber risks.

Before the engagement, the manufacturer faced inconsistent network segmentation, outdated industrial control systems (ICS), and poor visibility into OT-layer threats. These vulnerabilities not only posed serious operational risks but also made compliance with standards like IEC 62443 difficult.

NXFORT executed a multi-phased industrial cybersecurity transformation that:

• • Performed a comprehensive asset discovery and vulnerability assessment across all ICS/SCADA systems
• • Segmented OT networks and implemented secure zones with firewall micro-segmentation policies
• • Integrated passive network traffic monitoring for real-time anomaly detection and alerting
• • Provided staff training on OT incident response aligned with industry frameworks like NIST CSF

As a result, the client achieved a 60% reduction in security gaps, increased threat visibility across critical plant environments, and maintained continuous compliance with regional manufacturing security regulations. Most importantly, downtime risk was significantly minimized across all industrial sites.
