By mukul975. Updated August 2, 2026. Categories: System Administration.

Deploys and configures Tofino industrial firewalls (Belden/Hirschmann) to protect SCADA systems and PLCs, using deep packet inspection of OT protocols (Modbus, EtherNet/IP, OPC, S7comm) to enforce access control between ICS zones. Use when deploying zone-level firewall protection in front of PLCs/RTUs, enforcing IEC 62443 zone/conduit boundaries, or adding compensating controls for unpatchable legacy PLCs.
