This case study details the collaboration between Fortinet and NTT DATA in building a secure IT and OT infrastructure for a new 2.5 million square foot battery cell manufacturing facility. The project faced challenges such as construction delays and the need to avoid vendor lock-in while ensuring robust cybersecurity measures. Fortinet and NTT DATA provided a comprehensive solution that included the Fortinet Security Fabric platform, which integrates various security and networking products to facilitate quick deployment and interoperability. Key components of the solution included FortiGate Next-Generation Firewalls, FortiEDR for endpoint protection, and FortiNAC for endpoint visibility. The deployment also emphasized network segmentation and persistent threat monitoring to mitigate cyberattack risks. NTT DATA's global security operations center offered 24/7 monitoring, reducing the need for client-side security personnel. The case study highlights the successful integration of advanced technology and expertise to support the client's operational needs while ensuring security and flexibility as the facility ramps up production.
