Challenges and Best Practices for Securing Modern Operational Technology Networks


Operational technology (OT) is made of hardware and software that control and monitor physical processes in an enterprise. Traditionally, enterprises secured OT systems, such as industrial control systems, medical devices, and retail point of sales systems, via air gapping or by physically isolating them from IT networks. With the rise of smart devices and the Internet of Things (IoT), air gaps no longer work. By the end of 2023, 83% of enterprises expect to connect OT and IoT devices to their enterprise networks, according to Enterprise Management Associates (EMA) research. IT and OT are converging so that enterprises can analyze OT data, innovate, and optimize industrial systems. A new approach to OT security is required.     

Enterprises need to modernize network architecture to protect these critical assets, especially by updating their network security and modernizing their approach to network segmentation. This webinar will explore how enterprises can use OT-dedicated firewalls and zero trust network access to protect OT systems from malicious actors. Join industry analyst firm EMA and managed secure access service edge (SASE) provider Open Systems for a webinar that will explore:

  • Why legacy approaches to securing operational technology are failing
  • How you should update your network security and network access controls to protect this critical infrastructure
  • How a SASE solution can support your smart OT security strategy
