@Caute_cautim I believe you will find that 80-90% of Heavy manufacturers (discrete manufacturing, appliances, cars, etc.) are not prepared. Most believe that they will not or cannot be targets (at least that is what they would like to believe). A number of these folk (members of the Boards), believe they can self insure or that maybe IT will take care of it.
COVID has really expanded remote access to these systems and opened many doors that we closed at one point. It will be interesting to see if corporations begin closing down the remote access.
However for Industrial Control systems, I believe the percentage of readiness is lower but still (at least in MHO), relatively higher that folks would believe. Government agencies have a better handle on it.
