Palo Alto Networks VM-Series Virtual Next-Generation Firewall and iS5 Communications RAPTOR®

Industrial Control Systems and Operational Technology (OT) networks are increasingly under attack from a wide range of bad actors. Due to digitization, the need for connectivity to these networks has exposed these systems to threats. In response, operators have deployed a wide range of cybersecurity devices, including next-generation firewalls (NGFWs) with deep packet inspection of OT protocols. The use of best-in-class solutions for various network and security components provides good network security. Still, the side effect of these implementations is the proliferation of specialized boxes, causing siloed data and increased management and maintenance costs. These devices occupy valuable rack space, require re-cabling of the network, and can introduce additional points of failure. Furthermore, many cybersecurity devices used were not engineered to meet the demanding environmental requirements such as IEC 61850-3 for electric substations, or support high voltage DC power supplies.
