For anyone new to securing an operational technology (OT) network or industrial control systems (ICS) from cyber threats, gaining full visibility would probably seem like a logical first step. But then what? The fact is that visibility alone will not protect you. Visibility will not block intruders, protect endpoints, stop malware, segment the network, or prevent downtime. A better solution would do all that in real time rather than trying to remediate after the fact. Because once an intruder is inside your network, visibility will not get them out.
