The four pillars: identity, access, automation, fleet
Tell someone how to act on this idea. "Automation provisions and enforces that access, and fleet posture feeds back into access decisions."
Step 1 of 3
Everything in this job decomposes into four systems. Hold them in your head as a map, because the loop tests each one and the later modules go deep on each.
The pillars aren't independent. Identity, driven from an HRIS source-of-truth, feeds access. Automation provisions and enforces that access, and fleet posture feeds back into access decisions. A clean answer names the pillar and how it connects to the next one.

The Four Pillars as One System
Interactive diagram. Tab through its regions; each focused region shows its detail in the panel below.
Automation runs under everything; identity feeds access, and fleet posture feeds back into access decisions.
Each pillar maps to a later deep-dive module. If your identity story is strong but you've never designed a zero-touch fleet, the fleet pillar is where to spend prep time. Self-audit against the four before you go deep on any one.
