Key Points Nearly one in three manufacturers experienced a cyber incident in the past 12 months, either directly or through their supply chain, according to new Make UK research. The most common consequences were production downtime and increased operational costs, not data breaches. Among firms hit by supplier cyber attacks, 31% reported delays to customer deliveries and 31% reported reduced production capacity. Cyber resilience is an operational risk category now, sitting alongside quality, productivity, and health and safety. Defense and aerospace suppliers carry additional exposure because cyber incidents can cascade into missed deliveries on programs where schedule slippage has real consequences. The Production Floor Is the New Threat Surface Most discussions about manufacturing cyber risk stay at the IT layer: compromised credentials, phishing campaigns, ransomware payments. New research from Make UK moves the conversation where it actually belongs: the production line, the supply chain, and the delivery schedule.
