How many sensors do we need to monitor three factories?

Usually one for each network segment you want to watch at each site, which typically means one to three per plant. The number depends on where traffic can be copied: a SPANSPAN: switch port analyser. A switch setting that sends a copy of network traffic to one port, where a sensor can watch it. port on a plant's core switch often sees the traffic between office and production and between the SCADA servers and the line switches, while traffic inside a machine's own switch needs a sensor or TAPTAP: test access point. A small device that copies the traffic on a network cable for a sensor to watch. closer to it. Start with the boundary between office and production at each plant, then add the segments where controllers are programmed. Every plant needs a small host to run the sensor and a way to send alerts out. With NetSenX, each agent on a SPAN or TAP port counts as one device for the whole segment it watches, all plants appear in one dashboard, and the OTOT: operational technology. The computers that run machines, production lines, building systems and utilities. protocols are read from the Pro plan. The pricing page shows how many devices each plan includes.
