The Industry 4.0 vision propels the integration of advanced technologies into operational technology (OT) environments, creating sophisticated "smart factories." However, this convergence introduces complex cybersecurity challenges that demand advanced solutions. This presentation explores how Fortinet's OT security platform, leveraging AI and machine learning, addresses these evolving threats. By providing real-time visibility, anomaly detection, and automated response capabilities, Fortinet enables industries to proactively secure their critical infrastructure and maintain operational resilience in the face of increasingly intelligent cyberattacks.
