1. A system, comprising:
a processor; and
a memory, accessible by the processor, and storing instructions that, when executed by the processor, cause the processor to perform operations comprising:
transmitting a plurality of discovery probes from a plurality of respective entry points into an operational technology (OT) network, wherein the OT network comprises a plurality of industrial automation components configured to perform an industrial automation operation, and wherein the OT network comprises a plurality of network layers;
receiving a plurality of discovery data sets in response to the plurality of discovery probes, wherein each of the plurality of discovery data sets comprises data identifying a respective subset of a plurality of nodes within the OT network, wherein the respective subset of the plurality of nodes for a first discovery data set are disposed within at least two network layers of the plurality of network layers;
identifying a set of nodes within the OT network that appear in two or more of the plurality of discovery data sets;
generating a holistic discovery data set for the OT network based on the plurality of discovery data sets and the identified set of nodes within the OT network that appear in the two or more of the plurality of discovery data sets; and
generating a visualization of the plurality of nodes within the OT network based on the holistic discovery data set.
