Cyber Insurance for Manufacturing

Manufacturing's Unique Cyber Risk Profile

Manufacturing businesses in New Zealand face a cyber risk profile that is distinct from other sectors: the convergence of IT (information technology) and OT (operational technology) systems has created attack vectors that can cause physical production shutdowns and equipment damage, not just data theft. As factory floors become increasingly connected — with sensors, SCADA systems, PLCs and networked industrial equipment — the boundary between cyber risk and operational risk has effectively disappeared.

OT and SCADA System Vulnerabilities

Operational technology systems — including SCADA (Supervisory Control and Data Acquisition) systems, Programmable Logic Controllers (PLCs) and industrial control systems — were historically isolated from internet-connected networks. The push for operational efficiency and real-time monitoring has changed this: most modern manufacturing facilities now have some level of IT/OT integration that, if poorly secured, can allow ransomware to spread from business IT systems onto the factory floor.

Many NZ manufacturers also continue to operate legacy OT systems running outdated operating systems that no longer receive security updates — creating persistent vulnerabilities that cannot be easily patched without disrupting production.

Production Shutdown: The Dominant Risk

For manufacturers, business interruption is the primary cyber risk — exceeding data breach concerns in most cases. A ransomware attack that halts a production line does not just prevent goods from being produced: it triggers contractual penalties for delayed deliveries, damages customer relationships, and creates workforce cost inefficiencies as staff cannot work productively during the shutdown. At $50,000–$200,000 per day, even a 48-hour production halt can represent a significant financial hit that most businesses would struggle to absorb uninsured.

Supply Chain Compromise

Manufacturing supply chains create multiple third-party cyber risk vectors. Attackers who cannot penetrate a manufacturer's well-secured systems may instead target smaller, less secure suppliers, using compromised supplier access credentials or systems as a route into the manufacturer's network. This supply chain attack pattern is increasingly common globally and has affected NZ manufacturers connected to international supply chains.

Proprietary IP and Design Data

Manufacturing intellectual property — product designs, formulations, production processes and quality control documentation — represents significant competitive advantage that can be worth millions in R&D investment. State-sponsored actors, particularly targeting food technology, materials science and advanced manufacturing, are an increasing concern for NZ manufacturers operating in globally competitive sectors.

Cyber Insurance for Manufacturing

A specialist manufacturing cyber policy must specifically address production interruption loss (including OT/SCADA system downtime), not merely IT system business interruption. Confirm that your policy covers: OT system ransomware and restoration, production downtime business interruption, supply chain breach response, IP data breach, invoice fraud and BEC on supplier payments, and third-party product liability arising from a cyber-induced production error. OT coverage is a specialist area — not all general cyber policies include it adequately.
