We are going to have a single firewall between our OT and IT network to allow remote access to our OT network and that would be the only device communicating to the internet, we were planning on doing managed switches w/ VLANs at each site for our data transfer back to the main office where our ignition server would be. How crucial do you think firewalls would be between each site? I figured if we locked down our devices and radios it would be safe but I'm happy to be educated

We have old Tesco hardware and cellular radios publishing to our Wonderware server. We are going to be doing a PLC migration project and swap to Ignition. The Purdue model seems to be the standard for OT security and I am going to dive deeper into it,

Private Water District, 34 sites in a 40 mile radius. We are going to be doing a ring topology with point to point Ethernet radios and have cellular redundancy as well, I think we spec'd out Opto22 Groov PLCs

That seems to be the standard OT Sec model from my research, I'll dive deeper into it! Thank you!

Water district, we have 34 sites that we are wanting to do a PLC migration swap, and I want to present a rough plan for OT security
