1. A cyber safety system for protecting a site network, comprising:
a cyber monitoring logic to generate a cyber attack signal in response to a cyber attack event; and
a stand-alone automatic segmentation controller to generate a plurality of segmentation voltage signals or a plurality of segmentation messages in response to the cyber attack signal and provide them to a plurality of firewalls; and
the plurality of firewalls configured to invoke firewall rulesets depending upon an input voltage signal level of the plurality of segmentation voltage signals or the plurality of segmentation messages to segment the site network in a plurality of site network segments and to control one or more physical devices as response to the cyber attack event,
wherein the cyber safety system being an isolated separate stand-alone system from the site network that it is protecting,
wherein the cyber safety system provides Architecture Options which include a basic Architecture Option in which an Operational Technology (OT) space is isolated on a credible threat in a D milli second (ms) response time,
wherein the Architecture Options include a standard Architecture Option in which an OT space and equipment is isolated on a credible threat in a B ms response time,
wherein the Architecture Options include a high performance Architecture Option in which an OT space and equipment is isolated on a credible threat in an A ms response time,
wherein the Architecture Options include a high availability Architecture Option in which an OT space and equipment is isolated on a credible threat in a C ms response time, and
wherein the D ms is greater than the C ms which is greater than the B ms which is greater than the A ms.
