The systems that manage our critical infrastructure-from power grids and water treatment plants to manufacturing lines and transportation networks-are the unseen engines of modern society. These Industrial Control Systems (ICS) are complex networks of hardware and software that monitor and control physical processes. For decades, they operated in isolated, air-gapped environments, separated from the corporate IT world. However, the convergence of Information Technology (IT) and Operational Technology (OT) has erased these traditional boundaries, exposing vital industrial processes to a landscape of sophisticated cyber threats.

Network Access Control (NAC) has become a cornerstone of modern cybersecurity strategy, acting as a gatekeeper that verifies every user and device attempting to connect to a corporate network. As organizations embrace trends like Bring Your Own Device (BYOD), remote work, and the Internet of Things (IoT), the network perimeter has dissolved, making it critical to enforce security policies at the point of access. While the benefits are clear, the path to a successful NAC implementation is often filled with obstacles.
