OT Cybersecurity

Securing PLC and SCADA environments — network segmentation, hardening, and monitoring for critical operational technology, done by engineers who program the controllers they're protecting.

Operational technology security sits in a gap: IT security firms understand networks but not what happens when a controller is taken offline, and most automation contractors don't work at the network layer at all. Securing a live plant means knowing which PLC can tolerate a firewall rule, which interlock must never be interrupted, and how the SCADA polls its field devices — knowledge that comes from having built these systems, not from a scanning tool. Unifab approaches OT security from the controls side: our engineers program the Allen Bradley, Siemens, Mitsubishi, and Omron systems in question, and have delivered the network backbones and communication systems those plants run on. That combination is what lets segmentation and hardening happen without taking a process down.
