Network segmentation with a next-generation firewall (NGFW) is a critical first step in securing an operational technology (OT) network. Industrial firewalls for OT networks typically demand a tough exterior while also containing specific, purposebuilt controls and cybersecurity for unique industrial (non-IT) networks. Because networks and cybersecurity are not static, cybersecurity controls must be updated and refined to provide real-time protection in an ever-changing industrial and critical infrastructure threat landscape. Below are five key considerations in choosing an industrial (OT) firewall.
Ruggedize firewalls are designed to withstand heat and cold, dust, vibration, and other severe environmental conditions. Fortinet is a leader in traditional and ruggedized NGFWs. Fortinet designs both with advanced security processing units (SPUs) for all firewall types with a common operating system for ease of operation and integration with the Fortinet Security Fabric.
