Can an MSP offer OT monitoring to small manufacturers?
Yes, if it is passive and agreed with the people who run the machines. OTOT: operational technology. The computers that run machines, production lines, building systems and utilities. (operational technology) networks connect controllers, machines and building systems; they are fragile, rarely updated and often cannot run any security software. Passive monitoring from a mirror port reads the traffic without sending anything to the devices, which is what plant managers need to hear first. With NetSenX, from the Pro plan, the client's tenant reads Modbus/TCP, DNP3, BACnet/IP, EtherNet/IP and S7comm passively and raises OT alerts such as unauthorised writes, Purdue-level crossings, off-hours OT activity and S7comm commands. NetSenX never probes OT devices and is not a safety system; changes to the process stay with the client's engineers.
