A “Factory Cyber Security Programme” launched by Unilever in 2019 encompasses a comprehensive approach to cyber securing operational technology (OT) assets. After engaging factory teams to carefully identify and catalogue all connected OT systems and associated high-level cyber issues, robust network segmentation was implemented, leveraging next generation firewalls, to isolate OT assets from corporate IT infrastructure, ensuring a heightened security posture.

To enhance threat detection and response capabilities, endpoint detection and response (EDR) solutions were deployed across all factory environments. This allows for rapid identification and mitigation of potential cyberthreats, bolstering overall resilience. Concurrently, a proactive programme of patching and upgrading OT technology was instituted to eliminate exploitable vulnerabilities, further fortifying defences.

To provide ongoing visibility and oversight, each factory now benefits from a dedicated dashboard displaying vulnerability scores and performance metrics. This holistic approach not only ensures the integrity and security of OT assets but also underscores the company’s commitment to proactive cyber defence within its manufacturing ecosystem.
